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.

Absolute Monocytes

Monocytes (mono), similar to neutrophils, move to an area of infection and engulf and destroy bacteria. They are associated more often with chronic rather than acute infections. They are also involved in tissue repair and other functions involving the immune system.

Absolute Myelocytes (Only Reported If Detected)

Myelocytes are immature forms of white blood cells.

Absolute Neutrophils

Neutrophils (neu) normally make up the largest number of circulating WBCs. They move into an area of damaged or infected tissue, where they engulf and destroy bacteria or sometimes fungi. Young neutrophils, recently released into circulation, are called bands.

Absolute Nucleated Rbc (Only Reported If Detected)

Nucleated Red Blood Cells (nRBC) ) the presence of NRBCs in the adult blood is usually associated with malignant neoplasms, bone marrow diseases, and other serious disorders.

Absolute Promyelocytes (Only Reported If Detected)

Promyelocytes are immature forms of white blood cells.

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.

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.

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. 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.

MCH

Mean corpuscular hemoglobin (MCH) is a calculation of the average amount of oxygen-carrying hemoglobin inside a red blood cell.

MCHC

Mean corpuscular hemoglobin concentration (MCHC) is a calculation of the average percentage of hemoglobin inside a red cell.

MCV

Mean corpuscular volume (MCV) is a measurement of the average size of RBCs.

Metamyelocytes (Only Reported If Detected)

Metamyelocytes are immature forms of white blood cells.

Monocytes

Monocytes (mono), similar to neutrophils, move to an area of infection and engulf and destroy bacteria. They are associated more often with chronic rather than acute infections. They are also involved in tissue repair and other functions involving the immune system.

MPV

Mean Platelet Volume (MPV) - When it indicates average size of platelets are small; older platelets are generally smaller than younger ones and a low MPV may mean that a condition is affecting the production of platelets by the bone marrow. When it indicates a high number of larger, younger platelets in the blood; this may be due to the bone marrow producing and releasing platelets rapidly into circulation.

Myelocytes (Only Reported If Detected)

Myelocytes are immature forms of white blood cells.

Neutrophils

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.

Nucleated Rbc (Only Reported If Detected)

Nucleated Red Blood Cells (nRBC) ) the presence of NRBCs in the adult blood is usually associated with malignant neoplasms, bone marrow diseases, and other serious disorders.

Platelet Count

A platelet count is a test to measure how many platelets you have in your blood. Platelets help the blood clot. They are smaller than red or white blood cells.

Promyelocytes (Only Reported If Detected)

Promyelocytes are immature forms of white blood cells.

RDW

Red cell distribution width (RDW), which may be included in a CBC, is a calculation of the variation in the size of RBCs.

Reactive Lymphocytes (Only Reported If Detected)

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.

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

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.

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.

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: 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: 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: Iron and TIBC, Iron and Total Iron Binding Capacity TIBC, TIBC

% Saturation

Iron Binding Capacity

Total iron binding capacity (TIBC) is a blood test to see if you may have too much or too little iron in the blood. Iron moves through the blood attached to a protein called transferrin. This test helps your doctor know how well that protein can carry iron in the blood.

Iron, Total

Iron is a mineral that our bodies need for many functions. For example, iron is part of hemoglobin, a protein which carries oxygen from our lungs throughout our bodies. It helps our muscles store and use oxygen. Iron is also part of many other proteins and enzymes. Your body needs the right amount of iron. If you have too little iron, you may develop iron deficiency anemia. Causes of low iron levels include blood loss, poor diet, or an inability to absorb enough iron from foods. People at higher risk of having too little iron are young children and women who are pregnant or have periods.

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 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: Thyroid Stimulating Hormone Test, Thyrotropin Test

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.

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

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 Health, Oxygen Delivery & Iron Status

Fatigue often overlaps with blood count patterns, anemia, iron deficiency, low iron stores, and reduced oxygen delivery. This group helps evaluate whether the body has the blood and iron support needed for energy, stamina, mental clarity, and physical performance.

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 red blood cells and hemoglobin help carry oxygen throughout the body. Low hemoglobin, low hematocrit, anemia-related patterns, infection clues, immune changes, or platelet abnormalities may contribute to fatigue, weakness, dizziness, shortness of breath with exertion, low stamina, or poor recovery.

The CBC is one of the most useful first-line fatigue markers because it gives a broad view of oxygen-carrying capacity, immune activity, and general blood health.

Ferritin

Ferritin measures stored iron.

This test is included because low iron stores may contribute to fatigue, low energy, low stamina, restless legs, hair shedding, heavy period-related symptoms, weakness, dizziness, or poor exercise tolerance. Ferritin can help identify low iron stores even before anemia is obvious on a CBC.

Ferritin can also rise with inflammation, liver stress, metabolic issues, or iron overload, so it should be interpreted with iron/TIBC, CBC, hs-CRP, symptoms, and health history.

Iron and Total Iron Binding Capacity, TIBC

Iron and TIBC help evaluate circulating iron and iron transport capacity.

This test is included because ferritin alone does not fully show iron availability. Iron/TIBC provides additional context for iron deficiency, iron overload, anemia-related patterns, oxygen delivery, fatigue, weakness, and stamina.

Together, ferritin and iron/TIBC help create a more complete view of iron storage and iron availability.


Thyroid Function & Metabolic Energy

Thyroid hormones help regulate metabolism, energy production, body temperature, mood, bowel function, hair and skin health, and cognitive speed. Thyroid symptoms can strongly overlap with fatigue and brain fog.

TSH

TSH is a key thyroid screening marker.

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

TSH is often reviewed when fatigue is accompanied by cold intolerance, weight changes, constipation, hair thinning, low mood, or sluggishness.

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. TSH alone may not provide enough thyroid context for some people, especially when symptoms are persistent.

Free T4 may be useful when fatigue, cold intolerance, weight changes, constipation, low energy, or brain fog suggest possible thyroid involvement.


Blood Sugar, Metabolic Health & Energy Stability

Energy crashes, cravings, sleepiness after meals, poor focus, weight changes, and fatigue may overlap with blood sugar patterns. This group helps evaluate longer-term glucose regulation and general metabolic wellness.

Hemoglobin A1c

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

This test is included because blood sugar patterns may affect energy, focus, cravings, mood, metabolic wellness, and fatigue. A1c provides a longer-term view of glucose trends and may help support discussions about prediabetes, diabetes risk, metabolic fatigue, and energy crashes.

A1c is especially useful when fatigue overlaps with afternoon crashes, sugar cravings, weight changes, increased thirst, frequent urination, or a family history of diabetes.

Comprehensive Metabolic Panel, CMP

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

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

Abnormalities in electrolytes, kidney function, liver markers, glucose, calcium, albumin, or protein status may contribute to low energy or help guide follow-up discussions.


Inflammation & Recovery Context

Inflammation can contribute to fatigue, brain fog, body aches, poor recovery, and reduced energy. This group evaluates low-grade inflammation and helps interpret other markers such as ferritin.

hs-CRP

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

This test is included because inflammation may contribute to fatigue, brain fog, metabolic stress, cardiovascular risk, and poor recovery. hs-CRP also helps interpret ferritin because ferritin may rise with inflammation.

hs-CRP is nonspecific and should be interpreted with symptoms, medical history, medications, body composition, lifestyle factors, and other lab findings.


B Vitamins, Nerve Function & Brain Fog Support

Vitamin B12 and folate are important for red blood cell production, nerve function, DNA synthesis, methylation, and cognitive wellness. This group is especially relevant when fatigue overlaps with brain fog, numbness, tingling, weakness, mood changes, or restricted diets.

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 status may provide context for fatigue, brain fog, weakness, numbness, tingling, anemia-related patterns, mood changes, and cognitive concerns.

B12 and folate are especially important for people with vegetarian or vegan diets, restricted diets, digestive concerns, metformin use, acid-reducing medication use, or neurologic-type symptoms.


Vitamin D, Magnesium & Nutrient Support

Nutrient status can influence energy production, muscle function, immune resilience, mood, sleep, and recovery. This group evaluates two common nutrient areas that may overlap with fatigue and low energy.

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, muscle function, inflammation balance, mood, and general wellness. Low vitamin D status may overlap with fatigue, muscle aches, low resilience, and general wellness concerns.

Vitamin D is especially relevant for people with limited sun exposure, indoor lifestyles, darker skin tone, higher body weight, low vitamin D history, bone concerns, or muscle symptoms.

Magnesium

Magnesium supports muscle function, nerve signaling, sleep, glucose metabolism, blood pressure regulation, and energy production.

This test is included because magnesium may provide context for fatigue, muscle cramps, sleep quality, anxiety-like symptoms, blood sugar patterns, headaches, and nervous system function.

Magnesium can be useful to review when fatigue overlaps with cramps, poor sleep, stress, muscle tension, or metabolic concerns.


Urine Health, Hydration & Kidney Support

Hydration, kidney function, glucose handling, ketones, and urine findings may provide useful context when fatigue is present. This group adds a practical urine-based safety and wellness marker.

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 urine findings may provide context for hydration, kidney health, urinary findings, glucose handling, ketones, protein, and blood in urine.

Urinalysis can help identify patterns that may be relevant to fatigue, including dehydration, glucose or ketones in urine, urinary abnormalities, or kidney-related findings requiring provider review.
