Kidney (Renal) Function Test Panel in Massachusetts

A kidney (renal) function test panel is a group of blood tests that check how well your kidneys are filtering waste from your blood. It is often ordered as part of a routine checkup or to monitor conditions that can affect kidney health, such as diabetes or high blood pressure.

What it measures

Creatinine — A waste product from muscle that healthy kidneys remove. Higher levels can mean reduced kidney function.
Blood urea nitrogen (BUN) — Another waste product from protein breakdown. Levels can rise if kidneys are not filtering well.
Estimated glomerular filtration rate (eGFR) — A calculated number based on creatinine that estimates how much blood your kidneys filter per minute.
Electrolytes (sodium, potassium, chloride, bicarbonate) — Minerals that help your body work. Kidneys balance these, so abnormal levels can signal kidney issues.
Calcium and phosphorus — Minerals linked to bone health. Kidneys help regulate them, so changes may reflect kidney function.

Who it is for

A healthcare provider may order this panel if you have symptoms like swelling or fatigue, or if you have risk factors such as diabetes, high blood pressure, or a family history of kidney disease. It is also used to monitor people taking medications that can affect the kidneys.

Preparation

Fasting is usually not required for a kidney function panel, but your provider may ask you to fast if other tests are done at the same time. Drink water normally unless told otherwise.

Results and what they mean

Results are reported as numbers for each substance, often with a reference range. Your clinician interprets them based on your health history, medications, and other tests. This is general information, not medical advice; only a qualified professional can diagnose or treat any condition.

Frequently asked questions

Do I need to fast for this test?

Usually no. Fasting is not typically needed for a kidney function panel, but follow any instructions from your provider, especially if other tests are scheduled.

What do abnormal results mean?

Abnormal results can be caused by many things, including dehydration, medications, or kidney problems. Your clinician will consider your full picture and may repeat the test or order more.

How long does it take to get results?

Most results are available within 1 to 3 business days. Your provider's office will contact you if follow-up is needed.

Can I eat or drink before the test?

Yes, unless your provider says otherwise. Drinking water is fine and can even make the blood draw easier.
