Absolute Band Neutrophils (Only Reported If Detected)

Immature forms of neutrophils are called neutrophilic band cells. Neutrophils are a type of white blood cell that is responsible for much of the body's protection against infection. Neutrophils are produced in the bone marrow and released into the bloodstream to travel to wherever they are needed. Large numbers of immature forms of neutrophils, called neutrophilic band cells, are produced by the bone marrow when the demand is high.

Absolute Basophils

Basophils normally constitute 1% or less of the total white blood cell count but may increase or decrease in certain diseases and are thought to be involved in allergic reactions.

Absolute Blasts (Only Reported If Detected)

Blasts are immature forms of white blood cells.

Absolute Eosinophils

Eosinophils (eos) respond to infections caused by parasites and play a role in allergic reactions (hypersensitivities)

Absolute Lymphocytes

Lymphocytes are white blood cells that exist in both the blood and the lymphatic system. They are divided into three types. The B lymphocytes (B cells) are antibody-producing cells that are essential for acquired, antigen-specific immune responses. The second type are T lymphocytes (T cells) some T cells help the body distinguish between "self" and "non-self" antigens while others initiate and control the extent of an immune response, boosting it as needed and then slowing it as the condition resolves. Other types of T cells directly attack and neutralize virus-infected or cancerous cells. The third type are natural killer cells (NK cells) that directly attack and kill abnormal cells such as cancer cells or those infected with a virus.

Absolute Metamyelocytes (Only Reported If Detected)

Metamyelocytes are immature forms of white blood cells.

Blasts (Only Reported If Detected)

Blasts are immature forms of white blood cells.

Eosinophils

Eosinophils are specialized white blood cells produced in the bone marrow and released into the bloodstream, where they normally make up only 0–6 % of circulating leukocytes. Their cytoplasm is packed with reddish‑orange granules that contain potent enzymes (e.g., major basic protein, eosinophil cationic protein) and inflammatory mediators. When the immune system detects large, multicellular invaders—such as helminth (worm) parasites—eosinophils migrate out of the blood and surround the pathogen, releasing these granule contents to damage the parasite’s outer surface and aid its destruction. Beyond parasite defense, eosinophils act as key orchestras of the allergic response. They accumulate in tissues exposed to allergens (airways in asthma, skin in eczema, GI tract in eosinophilic esophagitis) and secrete cytokines and lipid mediators that amplify inflammation, recruit additional immune cells, and contribute to symptoms like swelling, mucus production, and itching. Because of this pro‑inflammatory role, persistently elevated eosinophil counts—termed eosinophilia—can signal allergic disorders, drug hypersensitivity, or certain autoimmune and malignant conditions. Conversely, counts drop toward zero after glucocorticoid therapy or in acute stress states, reflecting the cells’ sensitivity to hormonal and immune regulation.

Hematocrit

Hematocrit is a blood test that measures the percentage of the volume of whole blood that is made up of red blood cells. This measurement depends on the number of red blood cells and the size of red blood cells.

Hemoglobin

Serum hemoglobin is a blood test that measures the level of free hemoglobin in the liquid part of the blood (the serum). Free hemoglobin is the hemoglobin outside of the red blood cells. Most of the hemoglobin is found inside the red blood cells, not in the serum.

Lymphocytes

Lymphocytes are white blood cells that exist in both the blood and the lymphatic system. They are divided into three types. The B lymphocytes (B cells) are antibody-producing cells that are essential for acquired, antigen-specific immune responses. The second type are T lymphocytes (T cells) some T cells help the body distinguish between "self" and "non-self" antigens while others initiate and control the extent of an immune response, boosting it as needed and then slowing it as the condition resolves.

The third type are natural killer cells (NK cells) that directly attack and kill abnormal cells such as cancer cells or those infected with a virus.

Red Blood Cell Count

An RBC count is a blood test that tells how many red blood cells (RBCs) you have. RBCs contain hemoglobin, which carries oxygen. How much oxygen your body tissues get depends on how many RBCs you have and how well they work.

White Blood Cell Count

A WBC count is a test to measure the number of white blood cells (WBCs) in the blood. WBCs help fight infections. They are also called leukocytes. There are five major types of white blood cells: basophils, eosinophils, lymphocytes (T cells and B cells), monocytes and neutrophils

Also known as: Chem 12, Chemistry Panel, Chemistry Screen, CMP, Complete Metabolic Panel, Comprehensive Metabolic Panel CMP, SMA 12, SMA 20

Albumin

Albumin is a protein made by the liver. A serum albumin test measures the amount of this protein in the clear liquid portion of the blood.

Albumin/Globulin Ratio

The ratio of albumin to globulin (A/G ratio) is calculated from measured albumin and calculated globulin (total protein - albumin). Normally, there is a little more albumin than globulins, giving a normal A/G ratio of slightly over 1. Because disease states affect the relative amounts of albumin and globulin, the A/G ratio may provide a clue as to the cause of the change in protein levels. A low A/G ratio may reflect overproduction of globulins, such as seen in multiple myeloma or autoimmune diseases, or underproduction of albumin, such as may occur with cirrhosis, or selective loss of albumin from the circulation, as may occur with kidney disease (nephrotic syndrome). A high A/G ratio suggests underproduction of immunoglobulins as may be seen in some genetic deficiencies and in some leukemias. More specific tests, such as liver enzyme tests and serum protein electrophoresis, must be performed to make an accurate diagnosis. With a low total protein that is due to plasma expansion (dilution of the blood), the A/G ratio will typically be normal because both albumin and globulin will be diluted to the same extent.

Alkaline Phosphatase

Alkaline phosphatase (ALP) is a protein found in all body tissues. Tissues with higher amounts of ALP include the liver, bile ducts, and bone.

Alt

Alanine transaminase (ALT) is an enzyme found in the highest amounts in the liver. Injury to the liver results in release of the substance into the blood.

AST

AST (aspartate aminotransferase) is an enzyme found in high amounts in liver, heart, and muscle cells. It is also found in lesser amounts in other tissues.

Bilirubin, Total

Bilirubin is a yellowish pigment found in bile, a fluid made by the liver. A small amount of older red blood cells are replaced by new blood cells every day. Bilirubin is left after these older blood cells are removed. The liver helps break down bilirubin so that it can be removed from the body in the stool.

Bun/Creatinine Ratio

A ratio between a person’s BUN and blood creatinine to help determine what is causing these concentrations to be higher than normal. The ratio of BUN to creatinine is usually between 10:1 and 20:1. An increased ratio may be due to a condition that causes a decrease in the flow of blood to the kidneys, such as congestive heart failure or dehydration. It may also be seen with increased protein, from gastrointestinal bleeding, or increased protein in the diet. The ratio may be decreased with liver disease (due to decrease in the formation of urea) and malnutrition.

Calcium

You have more calcium in your body than any other mineral. Calcium has many important jobs. The body stores more than 99 percent of its calcium in the bones and teeth to help make and keep them strong. The rest is throughout the body in blood, muscle and the fluid between cells. Your body needs calcium to help muscles and blood vessels contract and expand, to secrete hormones and enzymes and to send messages through the nervous system.

Carbon Dioxide

CO2 is carbon dioxide. Measures the amount of carbon dioxide in the liquid part of your blood, called the serum. In the body, most of the CO2 is in the form of a substance called bicarbonate (HCO3-). Therefore, the CO2 blood test is really a measure of your blood bicarbonate level.

Chloride

Chloride is a type of electrolyte. It works with other electrolytes such as potassium, sodium, and carbon dioxide (CO2). These substances help keep the proper balance of body fluids and maintain the body's acid-base balance. This is a measure of the amount of chloride in the fluid portion (serum) of the blood.

Creatinine

The creatinine blood test measures the level of creatinine in the blood. This test is done to see how well your kidneys work.

Egfr African American

Glomerular filtration rate (GFR) is a test used to check how well the kidneys are working. Specifically, it estimates how much blood passes through the glomeruli each minute. Glomeruli are the tiny filters in the kidneys that filter waste from the blood.

Egfr Non-Afr. American

Globulin

Globulins is the collective term for most blood proteins other than albumin. Identifying the types of globulins can help diagnose certain disorders. Globulins are roughly divided into three groups: alpha, beta, and gamma globulins. Gamma globulines include various types of antibodies such as immunoglobulins (Ig) M, G, and A.

Glucose

A blood glucose test measures the amount of a sugar called glucose in a sample of your blood. Glucose is a major source of energy for most cells of the body, including those in the brain. The hormones insulin and glucagon help control blood glucose levels.

Potassium

Potassium is a mineral that the body needs to work normally. It helps nerves and muscles communicate. It also helps move nutrients into cells and waste products out of cells. A diet rich in potassium helps to offset some of sodium's harmful effects on blood pressure.

Protein, Total

The total protein is the total amount of two classes of proteins, albumin and globulin that are found in the fluid portion of your blood. Proteins are important parts of all cells and tissues. Your albumin helps prevent fluid from leaking out of blood vessels and your globulins are an important part of your immune system.

Sodium

Sodium is a substance that the body needs to work properly it is vital to normal body processes, including nerve and muscle function

Urea Nitrogen (Bun)

BUN stands for blood urea nitrogen. Urea nitrogen is what forms when protein breaks down. BUN measures the amount of urea nitrogen in the blood.

Also known as: Cortisol AM

Cortisol, A.M.

A cortisol level is a blood test that measures the amount of cortisol, a steroid hormone produced by the adrenal gland. The test is done to check for increased or decreased cortisol production. Cortisol is a steroid hormone released from the adrenal gland in response to ACTH, a hormone from the pituitary gland in the brain. Cortisol affects many different body systems. It plays a role in: bone, circulatory system, immune system. metabolism of fats, carbohydrates, and protein. ervous system and stress responses.

CYSTATIN C

eGFR

Also known as: Dehydroepiandrosterone Sulfate, DHEA SO4, DHEA Sulfate Immunoassay, DHEAS, Transdehydroandrosterone

DHEA SULFATE

DHEA-sulfate test measures the amount of DHEA-sulfate in the blood. DHEA-sulfate is a weak male hormone (androgen) produced by the adrenal gland in both men and women.

Estradiol

Estradiol (estradiol-17 beta, E2) is part of an estrogen that is a group of steroids that regulate the menstrual cycle and function as the main female sex hormones. Estrogens are responsible for the development of female sex organs and secondary sex characteristics and are tied to the menstrual cycle and pregnancy. They are considered the main sex hormones in women and are present in small quantities in men. Estradiol (E2) is the predominant form of estrogen and is produced primarily in the ovaries with additional amounts produced by the adrenal glands in women and in the testes and adrenal glands in men. Estradiol levels are used in evaluating ovarian function. Estradiol levels are increased in cases of early (precocious) puberty in girls and gynecomastia in men. Its main use has been in the differential diagnosis of amenorrhea – for example, to determine whether the cause is menopause, pregnancy, or a medical problem. In assisted reproductive technology (ART), serial measurements are used to monitor follicle development in the ovary in the days prior to in vitro fertilization. Estradiol is also sometimes used to monitor menopausal hormone replacement therapy.

Ferritin

Ferritin is a protein found inside cells that stores iron so your body can use it later. A ferritin test indirectly measures the amount of iron in your blood. The amount of ferritin in your blood (serum ferritin level) is directly related to the amount of iron stored in your body.

Also known as: Gamma Glutamyl Transferase GGT, Gamma-Glutamyl Transferase, Gamma-Glutamyl Transpeptidase, Gamma-GT, GGTP, GTP

Ggt

Gamma-glutamyl transpeptidase (GGT) is a test to measure the amount of the enzyme GGT in the blood.

Also known as: A1c, Glycated Hemoglobin, Glycohemoglobin, Glycosylated Hemoglobin, HA1c, HbA1c, Hemoglobin A1c, Hemoglobin A1c HgbA1C, Hgb A1c

HEMOGLOBIN A1C

The A1c test evaluates the average amount of glucose in the blood over the last 2 to 3 months. It does this by measuring the concentration of glycated (also often called glycosylated) hemoglobin A1c. Hemoglobin is an oxygen-transporting protein found inside red blood cells (RBCs). There are several types of normal hemoglobin, but the predominant form – about 95-98% – is hemoglobin A. As glucose circulates in the blood, some of it spontaneously binds to hemoglobin A. The hemoglobin molecules with attached glucose are called glycated hemoglobin. The higher the concentration of glucose in the blood, the more glycated hemoglobin is formed. Once the glucose binds to the hemoglobin, it remains there for the life of the red blood cell – normally about 120 days. The predominant form of glycated hemoglobin is referred to as HbA1c or A1c. A1c is produced on a daily basis and slowly cleared from the blood as older RBCs die and younger RBCs (with non-glycated hemoglobin) take their place. This test is used to monitor treatment in someone who has been diagnosed with diabetes. It helps to evaluate how well their glucose levels have been controlled by treatment over time. This test may be used to screen for and diagnose diabetes or risk of developing diabetes. In 2010, clinical practice guidelines from the American Diabetes Association (ADA) stated that A1c may be added to fasting plasma glucose (FPG) and oral glucose tolerance test (OGTT) as an option for diabetes screening and diagnosis. For monitoring purposes, an A1c of less than 7% indicates good glucose control and a lower risk of diabetic complications for the majority of diabetics. However, in 2012, the ADA and the European Association for the Study of Diabetes (EASD) issued a position statement recommending that the management of glucose control in type 2 diabetes be more "patient-centered." Data from recent studies have shown that low blood sugar (hypoglycemia) can cause complications and that people with risk of severe hypoglycemia, underlying health conditions, complications, and a limited life expectancy do not necessarily benefit from having a stringent goal of less than 7% for their A1c. The statement recommends that people work closely with their doctor to select a goal that reflects each person's individual health status and that balances risks and benefits.

Also known as: Homocysteine, Homocysteine Cardiovascular

HOMOCYSTEINE,

Also known as: C-Reactive Protein, Cardio CRP, Cardio hs-CRP, CRP, High Sensitivity CRP, High-sensitivity C-reactive Protein, High-sensitivity CRP, Highly Sensitive CRP, hsCRP, Ultra-sensitive CRP

Hs Crp

A high-sensitivity CRP (hs-CRP) test may be used by itself, in combination with other cardiac risk markers, or in combination with a lipoprotein-associated phospholipase A2 (Lp-PLA2) test that evaluates vascular inflammation. The hs-CRP test accurately detects low concentrations of C-reactive protein to help predict a healthy person's risk of cardiovascular disease (CVD). High-sensitivity CRP is promoted by some as a test for determining a person's risk level for CVD, heart attacks, and strokes. The current thinking is that hs-CRP can play a role in the evaluation process before a person develops one of these health problems.

Also known as: Insulin (fasting)

Insulin

Insulin is a hormone that is produced and stored in the beta cells of the pancreas. It is vital for the transportation and storage of glucose at the cellular level, helps regulate blood glucose levels, and has a role in lipid metabolism. When blood glucose levels rise after a meal, insulin is released to allow glucose to move into tissue cells, especially muscle and adipose (fat) cells, where is it is used for energy production. Insulin then prompts the liver to either store the remaining excess blood glucose as glycogen for short-term energy storage and/or to use it to produce fatty acids. The fatty acids are eventually used by adipose tissue to synthesize triglycerides to form the basis of a longer term, more concentrated form of energy storage. Without insulin, glucose cannot reach most of the body's cells. Without glucose, the cells starve and blood glucose levels rise to unhealthy levels. This can cause disturbances in normal metabolic processes that result in various disorders, including kidney disease, cardiovascular disease, and vision and neurological problems. Thus, diabetes, a disorder associated with decreased insulin effects, is eventually a life-threatening condition.

Also known as: Cholesterol, HDL,Fasting Lipids,Cholesterol, LDL, Fasting Lipids, Lipid Panel (fasting), Lipid Profile (fasting), Lipids

Chol/HDLC Ratio

Cholesterol, Total

Cholesterol is a waxy, fat-like substance that occurs naturally in all parts of the body. Your body needs some cholesterol to work properly. But if you have too much in your blood, it can combine with other substances in the blood and stick to the walls of your arteries. This is called plaque. Plaque can narrow your arteries or even block them. High levels of cholesterol in the blood can increase your risk of heart disease. Your cholesterol levels tend to rise as you get older. There are usually no signs or symptoms that you have high blood cholesterol, but it can be detected with a blood test. You are likely to have high cholesterol if members of your family have it, if you are overweight or if you eat a lot of fatty foods. You can lower your cholesterol by exercising more and eating more fruits and vegetables. You also may need to take medicine to lower your cholesterol.

HDL Cholesterol

LDL-Cholesterol

Non HDL Cholesterol

Triglycerides

Triglycerides are a form of fat and a major source of energy for the body. This test measures the amount of triglycerides in the blood. Most triglycerides are found in fat (adipose) tissue, but some triglycerides circulate in the blood to provide fuel for muscles to work. After a person eats, an increased level of triglycerides is found in the blood as the body converts the energy not needed right away into fat. Triglycerides move via the blood from the gut to adipose tissue for storage. In between meals, triglycerides are released from fat tissue to be used as an energy source for the body. Most triglycerides are carried in the blood by lipoproteins called very low density lipoproteins (VLDL). High levels of triglycerides in the blood are associated with an increased risk of developing cardiovascular disease (CVD), although the reason for this is not well understood. Certain factors can contribute to high triglyceride levels and to risk of CVD, including lack of exercise, being overweight, smoking cigarettes, consuming excess alcohol, and medical conditions such as diabetes and kidney disease.

Magnesium

Vitamin D, 25-Oh, D2

Vitamin D2 ((ergocalciferol,) is found in fortified foods and in most vitamin preparations and supplements. Vitamin D comes from two sources: endogenous, which is produced in the skin on exposure to sunlight, and exogenous, which is ingested in foods and supplements. The D2 form is found in fortified foods and in most vitamin preparations and supplements. Vitamin D2 is effective when it is converted by the liver and the kidney into the active form, 1,25-dihydroxyvitamin D.

Vitamin D, 25-Oh, D3

Vitamin D3 (cholecalcifero) which comes from animals. Vitamin D comes from two sources: endogenous, which is produced in the skin on exposure to sunlight, and exogenous, which is ingested in foods and supplements. Vitamin D3 is the form produced in the body and is also used in some supplements. Vitamin D3 are is converted by the liver and the kidney into the active form, 1,25-dihydroxyvitamin D.

Vitamin D, 25-Oh, Total

Vitamin D comes from two sources: endogenous, which is produced in the skin on exposure to sunlight, and exogenous, which is ingested in foods and supplements. The chemical structures of the types of vitamin D are slightly different, and they are named vitamin D2 (ergocalciferol, which comes from plants) and vitamin D3 (cholecalciferol, which comes from animals). The D2 form is found in fortified foods and in most vitamin preparations and supplements. Vitamin D3 is the form produced in the body and is also used in some supplements. Vitamin D2 and D3 are equally effective when they are converted by the liver and the kidney into the active form, 1,25-dihydroxyvitamin D.

Also known as: Free T3, FT3, T3 Free

T3, Free

This test measures the amount of triiodothyronine, or T3, in the blood.

Also known as: Free T4, FT4, T4 Free

T4, Free

The free T4 test is not affected by protein levels. Since free T4 is the active form of thyroxine, the free T4 test is may be a more accurate reflection of thyroid hormone function.

Also known as: Testosterone Total And Free And Sex Hormone Binding Globulin

Free Testosterone

In many cases, measurement of total testosterone provides the doctor with adequate information. However, in certain cases, for example when the level of SHBG is abnormal, a test for free or bioavailable testosterone may be performed as it may more accurately reflect the presence of a medical condition.

Sex Hormone Binding

The sex hormone binding globulin (SHBG) test measures the concentration of SHBG in the blood. SHBG is a protein that is produced by the liver and binds tightly to testosterone, dihydrotestosterone (DHT), and estradiol (an estrogen). In this bound state, it transports them in the blood as an inactive form. The amount of SHBG in circulation is affected by age and sex, by decreased or increased testosterone or estrogen production and can be affected by certain diseases and conditions such as liver disease, hyperthyroidism or hypothyroidism, and obesity. Changes in SHBG levels can affect the amount of testosterone that is available to be used by the body's tissues. A total testosterone test does not distinguish between bound and unbound testosterone but determines the overall quantity of testosterone. If a person's SHBG level is not normal, then the total testosterone may not be an accurate representation of the amount of testosterone that is available to the person's tissues.

TESTOSTERONE, TOTAL,

A testosterone test measures the amount of the male hormone, testosterone, in the blood. Both men and women produce this hormone. In males, the testicles produce most of the testosterone in the body. Levels are most often checked to evaluate signs of low testosterone: In boys -- early or late puberty and in men -- impotence, low level of sexual interest, infertility, thinning of the bones In females, the ovaries produce most of the testosterone and levels are most often checked to evaluate signs of higher testosterone levels, such as: decreased breast size, excess hair growth, increased size of the clitoris. irregular or absent menstrual periods and male-pattern baldness or hair thinning.

Thyroglobulin Antibodies

Measurement of thyroglobulin antibodies is useful in the diagnosis and management of a variety of thyroid disorders including Hashimoto's thyroiditis, Graves Disease and certain types of goiter.

Thyroid Peroxidase

Also known as: Thyroid Stimulating Hormone Test, Thyrotropin Test

TSH

A TSH test is a lab test that measures the amount of thyroid stimulating hormone (TSH) in your blood. TSH is produced by the pituitary gland. It tells the thyroid gland to make and release thyroid hormones into the blood.

Also known as: Serum Urate, UA

Uric Acid

Uric acid is a chemical created when the body breaks down substances called purines. Purines are found in some foods and drinks. These include liver, anchovies, mackerel, dried beans and peas, and beer. Most uric acid dissolves in blood and travels to the kidneys. From there, it passes out in urine. If your body produces too much uric acid or doesn't remove enough if it, you can get sick. A high level of uric acid in the blood is called hyperuricemia.

Also known as: UA, Complete, Urinalysis UA Complete, Urine Analysis, Complete

Amorphous Sediment (Only Reported If Detected)

Appearance

Bacteria

Bacteria are living things that have only one cell. Most bacteria won't hurt you - less than 1 percent of the different types make people sick. Many are helpful. Some bacteria help to digest food, destroy disease-causing cells, and give the body needed vitamins. But infectious bacteria can make you ill. They reproduce quickly in your body. Many give off chemicals called toxins, which can damage tissue and make you sick. Examples of bacteria that cause infections include Streptococcus, Staphylococcus, and E. coli.

Bilirubin

Bilirubin is a yellowish pigment found in bile, a fluid made by the liver. A small amount of older red blood cells are replaced by new blood cells every day. Bilirubin is left after these older blood cells are removed. The liver helps break down bilirubin so that it can be removed from the body in the stool.

Calcium Oxalate Crystals (Only Reported If Detected)

Calcium oxalate is a chemical compound that forms envelope-shaped crystals. A major constituent of human kidney stones.

Casts (Only Reported If Detected)

Urinary casts are cylindrical structures produced by the kidney and present in the urine in certain disease states. They form in the distal convoluted tubule and collecting ducts of nephrons, then dislodge and pass into the urine, where they can be detected by microscopy.

Color

Crystals (Only Reported If Detected)

Abnormal crystals may appear in urine as a result of pathology or due to normal catabolism

Glucose

A blood glucose test measures the amount of a sugar called glucose in a sample of your blood. Glucose is a major source of energy for most cells of the body, including those in the brain. The hormones insulin and glucagon help control blood glucose levels.

Granular Cast (Only Reported If Detected)

The second-most common type of cast, granular casts can result either from the breakdown of cellular casts or the inclusion of aggregates of plasma proteins (e.g., albumin) or immunoglobulin light chains. Depending on the size of inclusions, they can be classified as fine or coarse, though the distinction has no diagnostic significance. Their appearance is generally more cigar-shaped and of a higher refractive index than hyaline casts. While most often indicative of chronic renal disease, these casts, as with hyaline casts, can also be seen for a short time following strenuous exercise

Hyaline Cast

Urinary casts are tiny tube-shaped particles. Urinary casts may be made up of white blood cells, red blood cells, kidney cells, or substances such as protein or fat. The most common type of cast, hyaline casts are solidified Tamm-Horsfall mucoprotein secreted from the tubular epithelial cells of individual nephrons. Low urine flow, concentrated urine, or an acidic environment can contribute to the formation of hyaline casts, and, as such, they may be seen in normal individuals in dehydration or vigorous exercise. Hyaline casts are cylindrical and clear, with a low refractive index,

Ketones are substances produced in the liver when fat cells break down in the blood. A serum ketone test is a measurement of how many ketones are in the blood.

Leukocyte Esterase

Leukocyte esterase is a urine test to look for white blood cells and other signs associated with infection.

Nitrite

Occult Blood

The test looks for hidden (occult) blood in a specimen sample. It can find blood even if you cannot see it yourself.

Ph

Level of acid

Protein

Body fluids contain many different proteins that serve diverse functions such as transport of nutrients, removal of toxins, control of metabolic processes, and defense against invaders. Protein electrophoresis is a method for separating these proteins based on their size and electrical charge. When body fluids are separated by electrophoresis, they form a characteristic pattern of bands of different widths and intensities, reflecting the mixture of proteins present. This pattern is divided into five fractions, called albumin, alpha 1, alpha 2, beta, and gamma. In some cases, the beta fraction is further divided into beta 1 and beta 2. Albumin, which is produced in the liver, accounts for about 60% of the protein in the blood. "Globulins" is a collective term used to refer to proteins other than albumin. With the exception of the immunoglobulins and some complement proteins, most of the globulins are also produced in the liver. Immunofixation electrophoresis (IFE) is a method used to identify abnormal bands seen on serum, urine, or CSF protein electrophoresis, as to which type of antibody (immunoglobulin) is present.

Rbc

RBCs contain hemoglobin, which carries oxygen. How much oxygen your body tissues get depends on how many RBCs you have and how well they work.

Uric Acid Crystals (Only Reported If Detected)

Abnormal crystals may appear in urine as a result of pathology or due to normal catabolism

WBC

WBCs help fight infections. They are also called leukocytes. There are five major types of white blood cells: basophils, eosinophils, lymphocytes (T cells and B cells), monocytes and neutrophils

YEAST (Only Reported If Detected)

Candida is the scientific name for yeast. It is a fungus that lives almost everywhere, including in your body. Usually, your immune system keeps yeast under control. If you are sick or taking antibiotics, it can multiply and cause an infection.

Also known as: Cobalamin, Folic Acid, Vitamin B 12, Vitamin B 12 and Folic Acid, Vitamin B12 Cobalamin and Folate Panel Serum, Vitamin B12/Folic Acid

Folate, Serum

Folate is part of the B complex of vitamins and is measures the levels of folate in the liquid portion of the blood, the serum or plasma, to detect deficiencies. Folate is necessary for normal RBC formation, tissue and cellular repair, and DNA synthesis.. A deficiency inr folate can lead to macrocytic anemia. Megaloblastic anemia, a type of macrocytic anemia, is characterized by the production of fewer but larger RBCs called macrocytes, in addition to some cellular changes in the bone marrow.

Vitamin B12

Vitamin B12 is part of the B complex of vitamins and measurea the levels of vitamin B12 in the liquid portion of the blood, the serum or plasma, to detect deficiencies. Cobalamine, or vitamin B12, is found in animal products such as red meat, fish, poultry, milk, yogurt, and eggs and is not produced in the human body. In recent years, fortified cereals, breads, and other grain products have also become important dietary sources of B12. Vitamin B12 is necessary for normal RBC formation, tissue and cellular repair, and DNA synthesis. B12 is important for nerve health. A deficiency in B12 can lead to macrocytic anemia. Megaloblastic anemia, a type of macrocytic anemia, is characterized by the production of fewer but larger RBCs called macrocytes, in addition to some cellular changes in the bone marrow. B12 deficiency can lead to varying degrees of neuropathy, nerve damage that can cause tingling and numbness in the affected person's hands and feet.

Tests Included and Why They Matter

Blood Sugar, Insulin Resistance & Metabolic Function

Weight-loss resistance often overlaps with insulin resistance, blood sugar instability, cravings, energy crashes, and difficulty using stored fat efficiently. This group helps evaluate how the body handles glucose, insulin, and metabolic fuel.

Hemoglobin A1c

Hemoglobin A1c measures average blood sugar over approximately the past two to three months.

This test is included because long-term blood sugar patterns may provide context for prediabetes risk, diabetes risk, energy crashes, cravings, weight gain, and metabolic health. A1c is useful when weight-loss resistance overlaps with fatigue, increased hunger, abdominal weight gain, or family history of diabetes.

Insulin

Insulin helps move glucose from the bloodstream into cells.

This test is included because fasting insulin may provide important context for insulin resistance, one of the most common metabolic patterns associated with stubborn weight loss. Elevated insulin patterns may contribute to cravings, energy crashes, difficulty losing fat, and metabolic slowdown.

C-Peptide

C-peptide is released when the body makes insulin.

This test is included because it helps evaluate how much insulin the pancreas is producing. When reviewed with fasting insulin, glucose, and A1c, C-peptide may provide deeper context for insulin production, metabolic strain, beta-cell activity, and insulin resistance patterns.

Comprehensive Metabolic Panel, CMP

The CMP evaluates glucose, liver function, kidney function, electrolytes, calcium, albumin, total protein, and other metabolic markers.

This test is included because weight-loss and metabolism review benefits from a broad organ-function baseline. CMP findings may provide context for glucose, liver enzymes, kidney markers, hydration, electrolytes, calcium, protein status, and general metabolic wellness.

Thyroid Function & Autoimmune Thyroid Patterns

Thyroid hormones help regulate metabolism, energy production, body temperature, heart rate, bowel function, weight, and cognitive speed. Thyroid patterns can strongly overlap with slow metabolism, fatigue, and weight-loss resistance.

TSH

TSH is a key thyroid screening marker.

This test is included because thyroid function may influence metabolism, energy, weight, mood, body temperature, constipation, hair changes, and mental clarity. TSH provides an important starting point for thyroid-related weight and metabolism review.

T4, Free

Free T4 measures the available form of thyroxine, a thyroid hormone.

This test is included because Free T4 provides additional thyroid hormone production context when reviewed with TSH and symptoms. It may be useful when weight-loss resistance overlaps with fatigue, cold intolerance, constipation, dry skin, or low energy.

T3, Free

Free T3 measures the active form of thyroid hormone available in the bloodstream.

This test is included because T3 is closely tied to metabolism, energy output, body temperature, and fuel use. Free T3 may provide additional context for slow metabolism, restrictive dieting, fatigue, low body temperature, or weight-loss plateaus.

Thyroid Peroxidase and Thyroglobulin Antibodies

These antibodies help evaluate autoimmune thyroid patterns.

This test is included because autoimmune thyroid activity may contribute to thyroid dysfunction and symptoms such as weight changes, fatigue, brain fog, hair shedding, mood changes, and cold intolerance. Including thyroid antibodies adds depth beyond thyroid hormone levels alone.

Lipids, Cardiovascular Risk & Metabolic Health

Weight-loss resistance, insulin resistance, inflammation, thyroid function, and genetics can all affect cholesterol and triglyceride patterns. This group evaluates standard lipids and ApoB for deeper cardiometabolic insight.

Lipid Panel

The Lipid Panel measures total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides.

This test is included because lipid patterns provide cardiometabolic context for weight-loss resistance, insulin resistance, metabolic syndrome risk, and long-term cardiovascular wellness.

Apolipoprotein B

Apolipoprotein B, or ApoB, reflects the number of atherogenic cholesterol-carrying particles.

This test is included because ApoB may provide a deeper cardiometabolic risk view than LDL cholesterol alone. It may be especially useful when insulin resistance, high triglycerides, abdominal weight gain, or family history of heart disease are present.

Inflammation, Liver-Metabolic Stress & Uric Acid

Inflammation and liver-metabolic stress can contribute to insulin resistance, weight-loss difficulty, fatigue, and cardiometabolic risk. This group helps evaluate low-grade inflammation, bile-flow context, liver processing, ferritin patterns, homocysteine, and uric acid.

hs-CRP

High-sensitivity C-reactive protein is a marker of low-grade inflammation.

This test is included because inflammation may contribute to insulin resistance, metabolic stress, cardiovascular risk, fatigue, and weight-loss difficulty. hs-CRP also helps interpret ferritin, which may rise with inflammation.

Gamma Glutamyl Transferase, GGT

GGT is a liver and bile duct enzyme.

This test is included because GGT may provide context for liver stress, bile flow, fatty liver patterns, alcohol exposure, medication use, supplement use, and metabolic liver health. It is especially relevant in weight-loss resistance because fatty liver and insulin resistance often overlap.

Bilirubin, Fractionated

Bilirubin, Fractionated measures total, direct, and indirect bilirubin.

This test is included because bilirubin patterns provide additional liver processing and bile-flow context beyond standard liver enzymes. It can help support a broader liver-metabolism review.

Ferritin

Ferritin measures stored iron.

This test is included because ferritin may provide context for iron storage, inflammation, metabolic liver patterns, and fatigue. Ferritin can be elevated with inflammation or metabolic stress and low with iron deficiency, so it should be reviewed with hs-CRP and blood count patterns.

Homocysteine

Homocysteine is influenced by vitamin B12, folate, vitamin B6, methylation pathways, kidney function, and vascular health.

This test is included because it provides methylation, B-vitamin, vascular, and cardiometabolic context. It may be useful when weight-loss resistance overlaps with inflammation, cardiovascular risk, fatigue, or nutrient concerns.

Uric Acid

Uric acid is a metabolic waste product.

This test is included because uric acid may provide context for metabolic syndrome, insulin resistance, gout risk, kidney stone risk, high-protein diets, fructose intake, and cardiometabolic stress.

Hormone, Stress & Body Composition Context

Hormones can influence appetite, body composition, muscle mass, fat distribution, energy, sleep, libido, and metabolic rate. This group helps evaluate stress and sex-hormone patterns that may contribute to weight-loss resistance.

Cortisol, A.M.

Morning cortisol helps evaluate cortisol levels during the time of day when cortisol is commonly expected to be higher.

This test is included because cortisol may provide context for stress response, sleep-wake rhythm, stress eating, blood sugar regulation, belly fat concerns, fatigue, and metabolic resilience.

DHEA Sulfate, Immunoassay

DHEA-S is an adrenal androgen marker.

This test is included because DHEA-S may provide context for adrenal hormone patterns, stress physiology, aging-related hormone changes, energy, body composition, and hormone balance.

Testosterone, Total and Free and Sex Hormone Binding Globulin

This test evaluates total testosterone, free testosterone, and SHBG.

This test is included because testosterone availability may influence muscle mass, fat distribution, strength, libido, motivation, energy, and metabolic health in both men and women. SHBG helps interpret how much testosterone is available for use by the body.

Estradiol

Estradiol is a major form of estrogen.

This test is included because estradiol may provide context for weight changes, fat distribution, mood, sleep, perimenopause, menopause, libido, bone health, and hormone balance. Interpretation should consider sex, age, cycle timing, menopause status, hormone therapy, and symptoms.

B Vitamins, Nutrients & Methylation Support

Nutrient status can influence energy, methylation, cardiovascular risk, blood sugar metabolism, mood, and weight-loss efforts. This group evaluates key B-vitamin and nutrient markers that support metabolic interpretation.

Vitamin B12 and Folate Panel, Serum

This panel measures vitamin B12 and folate.

These nutrients support red blood cell production, nerve function, DNA synthesis, methylation, and general wellness. This test is included because B12 and folate may provide context for fatigue, metformin use, restricted diets, neuropathy-like symptoms, and homocysteine interpretation.

Vitamin B6, Pyridoxal Phosphate

Vitamin B6 is involved in methylation, neurotransmitter pathways, amino acid metabolism, immune function, and energy metabolism.

This test is included because B6 helps interpret homocysteine and methylation patterns and may provide useful nutrient context in an advanced metabolism panel.

Magnesium

Magnesium supports glucose metabolism, insulin sensitivity, muscle function, blood pressure regulation, sleep, and energy production.

This test is included because magnesium may provide context for metabolic health, muscle symptoms, blood sugar patterns, cravings, blood pressure, sleep quality, and general weight-loss wellness.

QuestAssureD™ 25-Hydroxyvitamin D, D2, D3, LC/MS/MS

Vitamin D testing measures vitamin D status.

This test is included because vitamin D supports bone health, immune function, inflammation balance, muscle function, and general metabolic wellness. Low vitamin D may overlap with fatigue, body composition concerns, and metabolic risk.

Kidney, Urine & Vascular Risk Context

Metabolic syndrome, insulin resistance, high blood pressure, and diabetes risk can affect kidney and vascular health. This group helps evaluate filtration, urine albumin, and urinalysis patterns.

Cystatin C with eGFR

Cystatin C with eGFR provides kidney filtration context beyond creatinine alone.

This test is included because kidney function can be affected by metabolic risk, insulin resistance, blood pressure, medications, hydration, and body composition. Cystatin C may help provide a more complete kidney filtration view than creatinine alone.

Albumin, Random Urine with Creatinine

This urine test evaluates albumin relative to creatinine.

It is included because urine albumin may provide early kidney and vascular stress context, especially when weight-loss resistance overlaps with insulin resistance, high blood pressure, diabetes risk, or cardiometabolic concerns.

Urinalysis, UA, Complete

A complete urinalysis evaluates urine markers such as protein, blood, glucose, ketones, specific gravity, pH, and other findings.

This test is included because urinalysis may provide context for hydration, kidney health, glucose handling, ketones, protein, and blood in urine.

Blood Health & General Wellness

CBC, includes Differential and Platelets

The CBC evaluates red blood cells, white blood cells, hemoglobin, hematocrit, platelets, and white blood cell types.

This test is included because weight-loss resistance and fatigue can overlap with anemia-related patterns, inflammation clues, immune patterns, platelet changes, and general blood health. It provides a foundational wellness marker for broader metabolic interpretation.
