What is a Blood Urea Test?

A blood urea test is a simple test to measure the amount of urea nitrogen in the blood. Urea nitrogen is a waste product produced by the body’s metabolism of proteins. The test is usually done as part of a routine health checkup and can help detect kidney problems. It can also be used to monitor the effectiveness of treatments for kidney or liver diseases. The test involves taking a small blood sample, usually from the arm, and sending it to a laboratory for analysis. Results are typically available within a few days.

Many potential health complications can stem from a high blood urea nitrogen (BUN) level. Some of the most common are renal failure, liver damage, and pancreatitis.

Here are seven key things to know about BUN levels and their relationship to health:

  1. Comprehensive Metabolic Panel (CMP)

The urea test is generally a part of a Comprehensive Metabolic Panel (CMP) used to diagnose and monitor kidney function. The urea test measures urea concentration in the blood. Urea is a waste product produced when the body breaks down proteins. A urea test checks urea nitrogen levels in the blood. Urea nitrogen is a waste product from protein metabolism that is removed from the body by the kidneys.

  1. Detection

A blood urea test’s results can indicate various conditions such as, 

  • Kidney disease
  • Dehydration
  • Malnutrition
