About this test
Urea and BUN blood test measures blood urea nitrogen levels to evaluate kidney function and help detect kidney disorders or abnormal protein metabolism.
The UREA and Blood Urea Nitrogen (BUN) test is a crucial diagnostic tool that measures the levels of urea and nitrogen in your blood. These levels provide valuable insights into kidney function and overall health. Urea is a waste product formed as the body processes proteins, and this test helps monitor how effectively your kidneys are filtering and eliminating it.

Important Instructions:

  • Inform the technician or doctor about any medications you are currently taking.

  • Mention if you are taking diuretics, steroids, or kidney-related medications.

  • Inform the technician if you have any kidney disease or ongoing treatment.

  • Tell the technician if you are taking blood thinners (anticoagulants).

  • Carry previous kidney test reports, if available, for better evaluation.
