What this test is
This panel measures several substances in the blood that reflect kidney and liver function. It typically includes tests for waste products, enzymes, and proteins that these organs regulate.
What it measures
- Creatinine — a waste product that reflects kidney filtration
- Blood urea nitrogen (BUN) — another waste product that indicates kidney function
- Estimated glomerular filtration rate (eGFR) — an estimate of how well the kidneys are filtering
- Alanine aminotransferase (ALT) — an enzyme that can indicate liver cell damage
- Aspartate aminotransferase (AST) — an enzyme that can reflect liver or muscle injury
- Alkaline phosphatase (ALP) — an enzyme related to liver and bile duct function
- Bilirubin — a substance that can rise with liver or bile issues
- Albumin — a protein that reflects liver synthetic function and nutritional status
What the test involves
A standard blood draw from a vein in your arm is used to collect the sample. The sample is then sent to a laboratory for analysis.
Why it is often ordered
A clinician may order these tests to screen for or monitor kidney or liver conditions, or to check how these organs are responding to certain medications. They can also be part of a routine health evaluation.
Preparation
Preparation instructions can vary depending on the specific tests included and the laboratory performing them. Always follow the collection lab's instructions, which may include fasting for a certain period before your appointment.
How results are reported
Results are reported as numerical values for each marker, often with a reference range provided by the laboratory. Reference ranges can vary between laboratories, so your results should be interpreted in the context of the lab that performed the test.
