What this test is
The BUN/Creatinine Ratio test evaluates the relationship between blood urea nitrogen (BUN) and creatinine levels. Both BUN and creatinine are waste products filtered out of the blood by the kidneys.

Blood Urea Nitrogen (BUN) — reflects protein breakdown and kidney filtration
Creatinine — reflects muscle metabolism and kidney filtration
What the test involves
This test requires a standard blood draw, where a healthcare professional will collect a sample of your blood from a vein, typically in your arm.
Why it is often ordered
Clinicians often order this test to help evaluate kidney function and detect potential kidney problems. It can also provide clues about other conditions affecting the body.
