The combined amount of cholesterol carried by the major blood lipoprotein groups.

Fats circulating in the blood that store energy from food the body does not immediately use.

The amount of cholesterol carried inside HDL particles in the blood.

The amount of cholesterol carried inside LDL particles, rather than the number of particles.

Calculated by subtracting HDL cholesterol from total cholesterol, capturing cholesterol in the remaining particles.

A protein carried by certain cholesterol-carrying particles; its amount reflects their total number.

The amount of glucose, the body's main circulating sugar and an energy source, in blood.

A major electrolyte that helps regulate fluid balance and supports nerve and muscle function.

An electrolyte needed for normal nerve signals, muscle contraction and heart function.

Amount of chloride, one of the blood's major electrolytes, measured in serum or plasma.

A blood chemistry result used to estimate bicarbonate when assessing the body's acid-base balance.

All testosterone circulating in blood, including protein-bound and unbound forms.

The portion of testosterone circulating without being attached to blood proteins.

Calculated

A protein made mainly by the liver that carries testosterone, estradiol and other sex hormones in blood.

The main estrogen during the reproductive years, produced primarily by the ovaries.

A pituitary hormone involved in ovulation and sex-hormone production in the ovaries and testes.

The portion of testosterone circulating without being attached to blood proteins.

A hormone produced after ovulation and during pregnancy, measured at a particular point in time.

A pituitary hormone that supports development of eggs in the ovaries and production of sperm.

A pituitary hormone that signals the thyroid gland to produce thyroid hormones.

The unbound portion of T4 thyroid hormone available to tissues, commonly considered alongside TSH.

The portion of thyroid hormone T3 circulating unbound to blood proteins.

Antibodies against an enzyme the thyroid uses to make thyroid hormones.

The combined direct and indirect forms of bilirubin, a waste product from red-cell breakdown.

An enzyme found especially in the liver, bile ducts and bones.

A liver-cell enzyme that can enter the blood when those cells are damaged.

An enzyme in the liver, muscles and other tissues that can enter blood when cells are damaged.

Nitrogen from urea in blood, a waste product formed when the body breaks down protein.

A waste product from normal muscle activity that the kidneys mainly remove from blood.

A calculated comparison of blood urea nitrogen with creatinine from the same collection.

An estimate of kidney filtration calculated from blood markers such as creatinine or cystatin C.

The total number of white blood cells in a given volume of blood.

The number of mature red blood cells in a given volume of blood.

The iron-containing protein in red blood cells that carries oxygen around the body.

The share of your blood volume occupied by red blood cells.

The average size of your red blood cells, reported as their volume.

Calculated average amount of hemoglobin, the oxygen-carrying protein, in each red blood cell.

The calculated average concentration of hemoglobin within packed red blood cells.

How much red blood cells vary in size, rather than their average size.

The number of platelets in a given volume of circulating blood.

The combined concentration of albumin and globulins, the main groups of blood proteins.

A liver-made blood protein that helps retain fluid and transport other substances.

Calculated amount of non-albumin blood proteins, found by subtracting albumin from total protein.
