Kidney & Liver Tests in Minnesota

Kidney & Liver Tests is a group of blood tests that checks how well your kidneys and liver are working. It is often ordered during a routine checkup, before surgery, or when symptoms or medicines suggest these organs need a closer look.

What it measures

Creatinine — A waste product filtered by the kidneys; higher levels can mean reduced kidney function.
Blood urea nitrogen (BUN) — Another kidney-filtered waste; read together with creatinine.
Estimated glomerular filtration rate (eGFR) — A calculated estimate of how much blood your kidneys filter each minute.
ALT and AST — Liver enzymes; leaking into blood can signal liver cell irritation.
ALP — A liver and bile-duct enzyme; changes can relate to bile flow.
Bilirubin — A yellow pigment processed by the liver; buildup can cause jaundice.

Who it is for

A primary care clinician, urgent care provider, or specialist may order these tests. They are common before starting medicines that affect the liver or kidneys.

Preparation

Fasting is often not required, but some labs ask for 8-12 hours without food if cholesterol or glucose is drawn at the same time. Tell the lab about all medicines and supplements you take.

Results and what they mean

Results are reported as numbers with a reference range, and your clinician interprets them alongside your history, symptoms, and other tests. One abnormal value does not by itself mean disease. This is general information, not medical advice; discuss your results with a qualified clinician.

Frequently asked questions

Do I need to fast?

Only if your clinician or lab says so. Many kidney and liver panels can be drawn without fasting.

How soon will I get results?

Typical turnaround is 1-3 business days, though it can vary by lab.

Can medicines affect the results?

Yes. Some prescription drugs, over-the-counter medicines, and supplements can change liver or kidney values, so share a full list with your clinician.

What if one value is outside the range?

A single out-of-range result is common and may be temporary. Your clinician will decide whether repeat testing or further evaluation is needed.
