Description

An ammonia plasma test measures the amount of ammonia in the blood. When intestinal bacteria break down proteins, ammonia is commonly formed. Once ammonia has been created, it becomes urea. The urine removes the urea. When the levels of ammonia in the blood start rising too rapidly, it is vital to ensure that the liver functions correctly. Cirrhosis or severe cases of hepatitis may be the culprits.

For the following reasons, an ammonia plasma test is often performed:

those receiving high-calorie IV nutrition supplements
to verify if the liver is functioning properly
to assess the extent of damage to the body or health effects of acute liver failure
measure the efficacy of current treatments for severe liver disease

The plasma ammonia test can help to detect possible health problems such as:
