Product Description

The liver produces urea in the urea cycle i.e., when proteins get digested. The ammonia produced during the urea cycle combines with carbon, hydrogen or oxygen to form urea. The urea is removed by the kidney and is filtered from the blood.
The urea is then excreted through the urine. If the concentration of the Urea is abnormal in the blood, it is highly indicative of a kidney disorder. Blood Urea Nitrogen is a very common test that gives you an indication of how well your kidneys and liver are working. A BUN test measures the amount of urea nitrogen in your blood.
