Renal Function Panel

The 12 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

• Phosphorus (Phosphate)

  Phosphorus is a mineral that builds bones and powers cells. Its blood level mostly reflects your kidneys, parathyroid glands, vitamin D and diet.

  18+

  2.5–4.5 mg/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
