Ammonia

An ammonia test measures the level of ammonia in the blood. Ammonia is a waste product formed primarily by the breakdown of proteins. The liver converts ammonia into urea, which is then excreted through the urine. High levels of ammonia in the blood can indicate liver dysfunction, kidney failure, or certain metabolic disorders, and it may cause symptoms like confusion, fatigue, and nausea. The test is often used to help diagnose conditions like hepatic encephalopathy or other issues related to liver function.
