Lab Test Library

The number and characteristics of red blood cells, white blood cells, and platelets in a single blood draw.

Eight substances: blood glucose, calcium, sodium, potassium, bicarbonate, chloride, BUN (blood urea nitrogen), and creatinine.

Everything in the BMP plus liver enzymes (AST, ALT, ALP, bilirubin) and total protein/albumin — 14 substances total.

Four types of blood fats: total cholesterol, LDL ('bad') cholesterol, HDL ('good') cholesterol, and triglycerides.

The percentage of hemoglobin coated with sugar — an average of your blood glucose levels over the past 2–3 months.

The amount of TSH in your blood — the pituitary gland's 'signal' telling the thyroid to make thyroid hormones.

The amount of unbound (active) thyroxine — the main thyroid hormone — circulating in the blood.

The protein in your cells that stores iron. Blood ferritin levels are the most reliable indicator of total body iron stores.

Serum iron (the iron in your blood), TIBC (how much iron your blood proteins could carry), and transferrin saturation (the percentage currently carrying iron).

The level of 25-hydroxyvitamin D in the blood — the storage form of vitamin D and the best indicator of your overall vitamin D status.

The concentration of cobalamin (B12) in your blood, a vitamin essential for nerve function, DNA production, and red blood cell formation.

Creatinine (a muscle waste product filtered by the kidneys) and eGFR (an estimate of how many mL of blood the kidneys filter per minute).

The color, concentration, and content of your urine — including glucose, protein, blood, ketones, nitrites, white blood cells, and pH.

Whether bacteria or other organisms are growing in your urine, and which antibiotics they are sensitive or resistant to.

A protein produced by both normal and cancerous prostate cells. Elevated PSA in the blood can be a sign of prostate issues.

The level of CRP, a protein produced by the liver in response to inflammation anywhere in the body.

How quickly red blood cells settle to the bottom of a tube over one hour — a proxy for inflammation. Inflammation makes cells clump together and sink faster.

Whether antibodies that attack the cell nucleus (a hallmark of autoimmune disease) are present in your blood, and at what level (titer).

How long it takes your blood to clot. PT is measured in seconds; INR standardizes that result across labs for consistent comparison.

The amount of glucose (sugar) circulating in your bloodstream at the time of the test.
