Comprehensive Metabolic Panel (CMP)

The 18 tests in this panel

What each one measures and the range labs usually print for adults. Ranges differ a little between labs, so the range on your own report is the one your result is judged against.

• Glucose

  Glucose is the sugar in your blood and your body's main fuel. This test shows how much is there at the moment the sample is drawn.

  Adults

  70–99 mg/dL

• Blood Urea Nitrogen (BUN)

  BUN is a waste product from protein breakdown that your kidneys clear from the blood, so it gives a rough read on kidney function and hydration.

  Men, 18+

  8–24 mg/dL

  Women, 18+

  6–21 mg/dL

• Creatinine

  Creatinine is a muscle waste product that your kidneys filter out, so the level in your blood is one of the main tools for checking kidney function.

  Men, 15+

  0.74–1.35 mg/dL

  Women, 16+

  0.59–1.04 mg/dL

• eGFR (Creatinine-based)

  An estimate of how well your kidneys filter blood, worked out from your creatinine, age and sex.

  18+

  60 and above mL/min/1.73 m²

• BUN/Creatinine Ratio

  A calculated comparison of your BUN with your creatinine that clinicians use as one clue to why a kidney-related number is high or low.

  Men, 18–59

  9–20 ratio

  Women, 18–59

  9–23 ratio

• Sodium

  Sodium is the main salt in your blood. This test shows how well your body balances water and salt.

  1+

  135–145 mmol/L

• Potassium

  Potassium is a mineral that helps your nerves, muscles and heart work. This test shows how much is in your blood.

  1+

  3.5–5.2 mmol/L

• Chloride

  Chloride is a salt mineral in your blood. It works with sodium to balance fluids and acid, and it is part of the basic and comprehensive metabolic panels.

  Adults

  96–106 mmol/L

• Bicarbonate (Total CO2)

  Bicarbonate, often printed as CO2 or total CO2, gives a clue about your body's acid-base balance. It is part of most routine blood panels.

  13+

  20–29 mmol/L

• Calcium, Total

  Total calcium is the amount of calcium in your blood. It supports your nerves, muscles, heart and bones, and it is on most routine panels.

  18–59

  8.7–10.2 mg/dL

  Men, 60+

  8.6–10.2 mg/dL

  Women, 60+

  8.7–10.3 mg/dL

• Protein, Total

  The total amount of protein in your blood, mainly albumin and globulin. It is read together with albumin and your liver and kidney tests.

  18+

  6–8.5 g/dL

• Albumin

  The main protein in blood plasma. Made by the liver, it keeps fluid inside your blood vessels and carries many substances.

  Adults

  3.5–5 g/dL

• Globulin, Total

  The proteins in your blood other than albumin, including antibodies. Most reports calculate it as total protein minus albumin.

  18+

  1.5–4.5 g/dL

• Albumin/Globulin (A/G) Ratio

  A calculated comparison of two groups of blood proteins, albumin and globulins. It is one clue about the liver, kidneys and immune system.

  Adults

  1.2–2.2 ratio

• Bilirubin, Total

  A yellow pigment made when old red blood cells break down. Your liver clears it, so the level reflects red cell turnover and bile flow.

  18+

  0–1.2 mg/dL

• Alkaline Phosphatase (ALP)

  An enzyme made mostly in your liver, bile ducts and bones. Its blood level gives clues about those tissues.

  Men, 19+

  40–129 U/L

  Women, 17+

  35–104 U/L

• Aspartate Aminotransferase (AST)

  An enzyme found mainly in the liver, and also in muscle and heart. Raised blood levels can be a sign of damage to those cells.

  Men, 14+

  8–48 U/L

  Women, 14+

  8–43 U/L

• Alanine Aminotransferase (ALT)

  An enzyme made mostly in liver cells. It leaks into the blood when liver cells are irritated or damaged.

  Men, 18+

  0–44 U/L

  Women, 18+

  0–32 U/L
