Showing 15 biomarkers
Hemoglobin A1c
HbA1c
HbA1c reflects average blood glucose levels over the past 2-3 months. It is commonly used to monitor long-term glucose control.
Fasting Plasma Glucose
Fasting Glucose
Fasting glucose measures blood sugar after an overnight fast. It is a common screening marker for prediabetes and diabetes.
LDL Cholesterol
LDL
LDL cholesterol is often referred to as "bad cholesterol." It carries cholesterol particles through the blood and can contribute to plaque buildup in arteries.
HDL Cholesterol
HDL
HDL cholesterol is often called "good cholesterol." It helps remove cholesterol from the bloodstream.
Triglycerides
Triglycerides
Triglycerides are a type of fat (lipid) found in the blood. After eating, the body converts calories it does not need into triglycerides.
Apolipoprotein B
ApoB
ApoB is a protein found on particles that carry cholesterol and triglycerides. It may provide additional cardiovascular risk information beyond standard lipid panels.
Lipoprotein(a)
Lipoprotein(a)
Lipoprotein(a) is a genetically determined lipid particle that may contribute to cardiovascular risk.
25-OH Vitamin D
Vitamin D
Vitamin D is important for bone health, immune function, and various other processes. The 25-OH form is the main circulating form measured in blood.
Vitamin B12
Vitamin B12
Vitamin B12 is essential for nerve function, red blood cell production, and DNA synthesis.
Ferritin
Ferritin
Ferritin is a protein that stores iron in cells. Serum ferritin reflects the total iron stores in the body.
Thyroid Stimulating Hormone
TSH
TSH is produced by the pituitary gland and stimulates the thyroid to produce thyroid hormones. It is the primary screening marker for thyroid function.
Hemoglobin
Hemoglobin
Hemoglobin is the protein in red blood cells that carries oxygen. It is a key marker in a complete blood count.
Creatinine
Creatinine
Creatinine is a waste product from muscle metabolism. It is filtered by the kidneys and is a key marker of kidney function.
Alanine Aminotransferase
ALT
ALT is an enzyme found mainly in the liver. Elevated levels can indicate liver cell irritation.
Aspartate Aminotransferase
AST
AST is an enzyme found in the liver, heart, and muscles. It is often measured alongside ALT.
