BUN

BUN measures the nitrogen from waste products in your blood, most of which the kidneys remove. It helps assess kidney function and the body's water balance.

What this test is

The test measures urea nitrogen produced when the body breaks down protein. Raised levels may reflect reduced kidney function, dehydration, gastrointestinal bleeding or a very high protein intake, so it is read together with creatinine.

What it is used for, and who should test

  • Assessing kidney function together with creatinine and eGFR
  • Monitoring patients on medicines that affect the kidneys or with chronic kidney disease
  • Investigating dehydration or fluid balance problems
