The normal ammonia range is 10â47 Î¼mol/L. High ammonia levels and signs of hepatic encephalopathy is a worsening of brain function that occurs when the liver is no longer able to remove toxic substances in the blood due to cirrhosis. Symptoms may be mild at first.
Ammonia then goes to the liver, where it is converted into urea, and this travels via the blood to the kidneys, where it is excreted out in urine as a waste product. So, blood tests can determine the level of BUN, or blood urea nitrogen, in your body as an important indicator of liver, and more so kidney, health. The normal range of BUN found in the blood is approximately 8 mg/dL - 18 mg/dL.
