: Serum
Also Known As: Trimethylamine N-Oxide Test

The TMAO test measures Trimethylamine N-oxide levels in the blood, a compound produced from dietary nutrients like choline and carnitine. Elevated TMAO has been linked to increased cardiovascular risk and may contribute to atherosclerosis. This test helps assess heart health and guide dietary or lifestyle interventions.


: Blood
 The Total Glutathione test measures the total amount of glutathione in the blood. Glutathione is a powerful antioxidant that plays a crucial role in protecting cells from oxidative stress, maintaining the immune system, and supporting various metabolic processes. This test provides valuable insights into the antioxidant capacity and overall health of an individual.

: Serum

The Transferrin Test measures transferrin, a protein that binds and carries iron in the blood. It helps evaluate iron status, diagnose iron deficiency or overload, and assess conditions affecting iron metabolism, nutrition, or liver function.


: Serum
Also Known As: TG Test, TRIG Test

The Triglycerides Test measures the amount of triglycerides, a type of fat, in the blood. Elevated levels may increase the risk of heart disease, stroke, and pancreatitis. This test helps assess metabolic health, identify risk factors, and monitor the effects of lifestyle changes or treatment.


: Serum
Also Known As: TnI Test, cTnI Test, Troponin Test

The Troponin I Test measures levels of troponin I, a protein released into the blood when the heart muscle is damaged. It is most commonly used to help diagnose heart attacks, assess the severity of cardiac injury, and monitor for other conditions that affect the heart. Elevated levels typically indicate recent or ongoing heart muscle damage.


Most Popular
: Serum
Also Known As: Thyroid Stimulating Hormone Test, Thyrotropin Test

The TSH (Thyroid Stimulating Hormone) test measures TSH levels, a pituitary hormone that regulates thyroid function. It helps diagnose and monitor hypothyroidism, hyperthyroidism, and other thyroid disorders. Abnormal levels may indicate hormone imbalances and guide treatment decisions.


: Serum
Also Known As: BUN Test

The Blood Urea Nitrogen (BUN) Test measures the amount of urea nitrogen in the blood, a waste product made when protein is broken down. It helps assess kidney function, detect kidney disease, and monitor conditions such as dehydration, liver function, or the effects of certain medications.


Most Popular
: Serum
Also Known As: Serum Urate Test

The Uric Acid Test measures uric acid levels in the blood to help diagnose gout, monitor uric acid levels in people with kidney stones, and assess kidney function. High or low levels may indicate metabolic or kidney-related disorders.


: Random
Also Known As: Urine Analysis Test, UA Test, Complete Urinalysis Test

The Urinalysis Complete test examines the physical, chemical, and microscopic properties of urine to help detect urinary tract infections, kidney disease, diabetes, and other conditions affecting the urinary system.


: Random
 The Protein Total Random Urine test is a medical laboratory analysis that measures the total amount of protein present in a random urine sample. This test provides valuable insights into kidney function and other potential health conditions.

: Serum

: Plasma-Unspecified Vial Pour
 The Vascular Endothelial Growth Factor (VEGF) test is a laboratory test that measures the levels of VEGF in the blood. VEGF is a protein that plays a crucial role in angiogenesis, which is the process of new blood vessel formation. Produced by a variety of cells, VEGF can stimulate vascular endothelial cells to grow, migrate, and form new blood vessels.

: Serum
Also Known As: B12 Test, Cobalamin Test

The Vitamin B12 Micronutrient Test measures blood levels of vitamin B12, essential for red blood cell production, nerve health, and DNA synthesis. Deficiency can cause anemia, fatigue, neurological issues, and cognitive changes. This test helps identify dietary deficiencies, absorption problems, or related health conditions, supporting diagnosis and ongoing management of overall wellness.

Patient must be 18 years of age or older.

: Serum
Also Known As: B12 Test, Cobalamin Test

The Vitamin B12 test measures the levels of vitamin B12 in the blood, which is an essential nutrient for various bodily functions. It assesses the concentration of vitamin B12 to evaluate its availability for proper red blood cell production, nervous system function, and DNA synthesis. The test helps diagnose vitamin B12 deficiency or monitor the effectiveness of vitamin B12 supplementation.


: Serum
Also Known As: Cobalamin and Folic Acid Test, Vitamin B12 and Vitamin B9 Test

The Vitamin B12 and Folate Test measures blood levels of vitamin B12 and folate, essential nutrients for red blood cell production, nerve function, and DNA synthesis. It helps diagnose deficiencies that can cause anemia, fatigue, neurological issues, and other health problems.


: Serum
Also Known As: Ergocalciferol Test, Vitamin D2 Test, Cholecalciferol Test, Vitamin D3 Test, Calcidiol Test, 25-hydroxyvitamin D Test, Calcifidiol Test, 25-hydroxy-vitamin D Test, Vitamin D Total Test

The QuestAssureD™ Vitamin D Test measures total 25-hydroxyvitamin D, including D2 and D3, to assess vitamin D status. It helps evaluate bone health, calcium absorption, and risk for deficiencies or excess, guiding nutrition and treatment decisions.


Also Known As: VLDL Test, VLDL-C Test, Very Low-Density Lipoprotein Cholesterol Test

The VLDL Cholesterol Test measures very low-density lipoprotein (VLDL) cholesterol, which carries triglycerides in the blood. High levels are linked to plaque buildup in arteries and increased risk of heart disease. This test helps assess cardiovascular risk and guide lipid management.


: Plasma-Unspecified Vial Pour
Also Known As: VWF Ag Test, VWF RCo Test, von Willebrand Panel Test, Ristocetin Cofactor Test
The von Willebrand Factor Antigen test is a diagnostic tool that measures the quantity of von Willebrand Factor (vWF) present in a person's blood. vWF is a protein that plays a crucial role in the blood clotting process. It works by helping platelets in the blood stick together and adhere to the walls of blood vessels, which is a primary step in the clot formation process.

: Blood
Also Known As: Zn RBC Test, Zn Test

The Zinc RBC Test measures zinc levels inside red blood cells, providing a more accurate reflection of long-term zinc status than serum testing. Zinc is essential for immune function, wound healing, growth, and metabolism. This test helps detect deficiency or excess and evaluate overall nutritional health.
