The Ferritin Test measures ferritin, a protein that stores iron in the body, to evaluate iron levels and detect deficiency or overload. It helps diagnose anemia, iron deficiency, hemochromatosis, and chronic disease-related inflammation. Doctors often order the ferritin test to investigate fatigue, weakness, or unexplained symptoms. It is also used to monitor iron supplementation, treatment effectiveness, and overall iron metabolism health.

The Fibrinogen Activity Test measures how well fibrinogen, a key clotting protein, helps blood form clots. Low fibrinogen may indicate excessive bleeding, liver disease, or disseminated intravascular coagulation (DIC), while high levels may signal inflammation or increased clotting risk. Doctors use this test to evaluate unexplained bleeding, monitor clotting disorders, or assess liver function. Results provide vital insight into coagulation health and treatment management.

The Fructosamine Test measures average blood glucose levels over the past 2–3 weeks by evaluating glycated proteins. Unlike the HbA1c test, which reflects long-term control, this test provides a shorter-term view, making it useful for monitoring recent treatment changes, pregnancy, or conditions affecting red blood cells. Doctors use it to assess diabetes management, adjust medications, and evaluate how well blood sugar is being controlled.

The FSH and LH Test measures follicle-stimulating hormone (FSH) and luteinizing hormone (LH) to evaluate reproductive and endocrine health in both men and women. In women, it helps assess menstrual irregularities, infertility, menopause, or polycystic ovary syndrome (PCOS). In men, it aids in diagnosing low testosterone, infertility, or testicular dysfunction. Doctors also use this test to investigate puberty disorders, hormone imbalance, and pituitary function.

The Gastrin Test measures gastrin hormone levels in blood, which regulate stomach acid production. Elevated levels may indicate Zollinger-Ellison syndrome, gastrinoma, pernicious anemia, or chronic atrophic gastritis. Doctors order this test for patients with recurrent ulcers, abdominal pain, or unexplained diarrhea. Results help evaluate abnormal acid production, detect tumors, and guide treatment for gastrointestinal and metabolic conditions.

The GGT Test measures gamma-glutamyl transferase, an enzyme found in the liver and bile ducts, to evaluate liver health. Elevated GGT may indicate liver disease, bile duct obstruction, alcohol use, or medication side effects. Doctors order this test to investigate symptoms like fatigue, jaundice, dark urine, or abdominal pain and to monitor liver damage. It is often performed with other liver tests to provide a complete picture of liver and bile duct function.

The Homocysteine Test measures homocysteine levels in blood to assess risk for heart disease, stroke, and vascular problems. Elevated homocysteine may result from vitamin B6, B12, or folate deficiency and is linked to blood clots, cognitive decline, and osteoporosis. Doctors use this test to evaluate cardiovascular risk, monitor nutritional deficiencies, and guide treatment for metabolic or genetic conditions affecting homocysteine metabolism.

The High-Sensitivity C-Reactive Protein (hs-CRP) Test measures very low levels of CRP in blood to evaluate inflammation and cardiovascular risk. Elevated hs-CRP may indicate increased risk for heart disease, heart attack, or stroke even before symptoms appear. Doctors use this test along with cholesterol and other markers to assess overall heart health, guide prevention strategies, and monitor treatment. It also helps evaluate chronic inflammation and metabolic conditions.

The IGF-1 Test measures insulin-like growth factor 1, a hormone regulated by growth hormone (GH), to assess growth and endocrine function. Abnormal levels may indicate growth disorders, acromegaly, gigantism, or GH deficiency. Doctors order this test to evaluate delayed growth, short stature, excessive growth, or pituitary disease and to monitor GH therapy. Results provide valuable insight into hormone balance, metabolism, and overall endocrine health.

The Insulin Test measures insulin levels in blood to assess how the body regulates glucose and metabolism. It helps diagnose insulin resistance, hypoglycemia, type 2 diabetes, and metabolic syndrome. Doctors also use it to evaluate pancreatic function and monitor treatment effectiveness. Frequently ordered with glucose testing, the insulin test provides critical insight into endocrine health, blood sugar control, and risk for diabetes-related complications.

The Iron Total and Total Iron Binding Capacity (TIBC) Test measures iron levels in blood along with the blood’s ability to transport iron. It helps diagnose iron deficiency anemia, iron overload (hemochromatosis), and monitor nutritional or chronic health conditions. Low iron or high TIBC may indicate anemia, while high iron or low TIBC can suggest overload. Doctors use this test to evaluate fatigue, weakness, or other symptoms linked to iron and metabolic health.

The Lactate Dehydrogenase (LDH) Test measures LDH enzyme levels in blood to assess tissue damage and overall health. Elevated LDH may indicate conditions such as liver disease, heart attack, anemia, infections, or certain cancers, while low levels are uncommon. Doctors use this test to help diagnose disease, monitor treatment effectiveness, and track cell damage. It provides valuable insight into metabolic activity and organ function.

The Lead Blood Test measures lead levels in blood to detect exposure or poisoning. Even small amounts of lead can harm the nervous system, kidneys, and blood cells. High levels may cause developmental delays in children, fatigue, abdominal pain, or anemia in adults. Doctors use this test to monitor workplace exposure, environmental risks, or treatment effectiveness. Results provide essential insight into toxic exposure and long-term health protection.

The Lead Micronutrient Blood Test measures lead levels in the blood to assess exposure and potential toxicity. Lead, often found in contaminated water, soil, paint, or industrial settings, can harm the brain, nervous system, kidneys, and red blood cell production. This test helps detect harmful exposure, guide treatment, and monitor health risks related to lead accumulation.

The Leptin Test measures leptin hormone levels in blood to evaluate metabolism, appetite regulation, and body fat balance. Abnormal levels may indicate obesity, metabolic syndrome, insulin resistance, or leptin deficiency. Doctors use this test to assess unexplained weight gain, difficulty losing weight, or potential endocrine disorders. It also supports research on energy balance, fertility, and overall metabolic health management.

The Lipase Test measures levels of lipase, an enzyme made by the pancreas that helps digest fats. Elevated lipase may indicate acute or chronic pancreatitis, pancreatic cancer, gallbladder disease, kidney failure, or bowel obstruction. Doctors order this test to investigate severe abdominal pain, nausea, or vomiting and to monitor pancreatic disorders. Results provide vital insight into digestive health, pancreatic function, and overall gastrointestinal balance.

The Lipid Panel Test checks six key blood lipids: total cholesterol, HDL cholesterol, LDL cholesterol, non-HDL cholesterol, triglycerides, and the Chol/HDL ratio. This panel assesses risk for cardiovascular disease, heart attack, and stroke by evaluating cholesterol balance and fat levels in the blood. Doctors use lipid panel results for routine screening, treatment monitoring, and guiding lifestyle or medication adjustments.

The Lipoprotein (a) Test measures Lp(a), a genetic form of LDL cholesterol linked to higher risk of heart disease, stroke, and atherosclerosis. Unlike standard cholesterol tests, Lp(a) levels are inherited and not easily lowered by lifestyle changes. Doctors order this test for patients with a family history of early cardiovascular disease or high cholesterol. Results help identify hidden risk, guide prevention strategies, and support heart and vascular health management.

The Magnesium Micronutrient RBC Test measures magnesium levels within red blood cells, providing a more accurate assessment of long-term magnesium status than serum tests. Magnesium is vital for muscle and nerve function, energy production, bone strength, and heart health. This test helps detect deficiencies or imbalances from poor diet, absorption issues, or medical conditions, supporting overall wellness.
