Kidney function tests measure how efficiently your kidneys are working. Most of these tests check how well your kidneys clear waste from your system. A kidney test may involve a blood test, 24-hour urine sample or both. You usually have your test results the same day or within a few days.

Kidney function tests are urine or blood tests that evaluate how well your kidneys are working. Most of these tests measure glomerular filtration rate (GFR). GFR assesses how efficiently your kidneys clear waste from your system.

Your healthcare provider may order one or a few different types of kidney function tests. You may have blood tests for kidney function, such as:

Blood urea nitrogen (BUN) measures nitrogen (made from protein breakdown) in your blood.
Estimated GFR (eGFR) calculates filtration rates based on your protein levels, age, gender, size and race.
Serum creatinine looks for the buildup of creatinine, a waste product from muscle tissue breakdown.
Your healthcare provider may also use 24-hour urine tests, including:

Microalbuminuria looks for a specific protein called albumin.
Urinalysis evaluates your urine for blood, proteins and function.

You complete 24-hour urine tests at home. For a 24-hour urine test, your provider will give you a container to collect urine. On the day of the test:

Urinate into the toilet as usual after you first wake up.
For the rest of the day, urinate into the container.
On day two, urinate into the container when you first wake up.
Complete the test by dropping your sample off at the healthcare provider’s office or laboratory.
