The Ammonia test is a blood test that measures the levels of ammonia in the blood. Ammonia is a waste product produced by the body when proteins are broken down, and is normally converted by the liver into a less harmful substance called urea, which is excreted in the urine. The ammonia test is commonly used to evaluate liver function and diagnose and monitor conditions that affect the liver, such as liver disease or liver failure. Elevated levels of ammonia in the blood can indicate liver damage or disease, as well as other conditions that affect the body’s ability to process proteins, such as kidney failure or certain genetic disorders. The ammonia test involves taking a small sample of blood, which is then analyzed in a laboratory to determine the levels of ammonia. Depending on the results of the test, doctors may recommend additional diagnostic tests or treatments to address underlying conditions. Regular monitoring of ammonia levels can also be used to track the progression of liver disease and evaluate the effectiveness of treatment.
