What this test is

The Kidney Function Panel is a group of blood and urine tests that assess how well your kidneys are working. It typically includes measures of waste products, electrolytes, and proteins. Together, these tests help evaluate overall kidney function.

What it measures

  • Creatinine — a waste product that reflects how well the kidneys filter
  • Blood Urea Nitrogen (BUN) — another waste product that indicates kidney function
  • Estimated Glomerular Filtration Rate (eGFR) — an estimate of the kidneys' filtering capacity
  • Electrolytes (Sodium, Potassium, Chloride, Bicarbonate) — minerals that help maintain fluid and acid-base balance
  • Calcium and Phosphorus — minerals that are regulated by the kidneys
  • Albumin — a protein that can indicate kidney damage if present in urine

What the test involves

The panel usually requires a blood sample drawn from a vein in your arm. You may also be asked to provide a urine sample, depending on the specific tests included.

Why it is often ordered

A clinician may order this panel to screen for kidney problems, especially if you have conditions like diabetes or high blood pressure. It can also help monitor kidney function if you are taking medications that affect the kidneys or have known kidney disease.

Preparation

Preparation instructions can vary depending on the specific tests included, so follow the collection lab's directions. In many cases, no special preparation is needed, but you should confirm with the lab.

How results are reported

Results are reported as numeric values for each marker, often with a reference range provided by the testing laboratory. Reference ranges can differ between labs, so your results should be interpreted in the context of the lab that performed the test.

Before you go

  • Whether fasting is required for your specific panel
  • If a urine sample is needed in addition to a blood draw
  • Any medications or supplements that might affect the test results
