High-sensitivity C-reactive protein (hs-CRP)

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

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.

Conditional. Reported if BUN or creatinine is abnormal.

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

Protein detected or measured in urine; a dipstick mainly detects albumin.

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

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

The average size of circulating platelets, distinct from how many platelets are present.

White blood cells that play a central role in the body's early immune responses.

A group of white blood cells involved in the body's immune responses.

White blood cells that help remove damaged cells and microbes and can develop into tissue immune cells.

A type of white blood cell, reported as a count or percentage of white cells.

White blood cells involved in allergic reactions and inflammatory signaling.

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.

The observed color of urine, assessed visually or with a laboratory instrument.

A visual description of how clear or cloudy the urine sample looks.

Urine density compared with water, providing a time-specific estimate of how concentrated the urine is.

A urine-strip test for heme, which can come from red cells, hemoglobin or muscle pigment.

A urine-strip reaction that indirectly checks for white blood cells, rather than counting them directly.

A urine-strip result detecting nitrite formed by some bacteria, rather than directly counting bacteria.

How acidic or alkaline a urine sample is at the time of testing.

White blood cells counted directly in urine, distinct from the indirect leukocyte-esterase strip test.

Conditional. Microscopy only if protein, leukocyte esterase, blood or nitrites is positive.

Red blood cells counted in urine, distinct from a dipstick test for blood pigments.

Conditional. Microscopy only if protein, leukocyte esterase, blood or nitrites is positive.
