CAUSES OF HIGH AMMONIA. Ammonia is a normal by-product of processing nitrogen in the body, and is excreted as waste in the urine, in healthy people. However, elevated blood ammonia levels can occur when the kidneys or liver are not working properly, allowing this waste to remain in the bloodstream, which can be poisonous to your cells.
Blood Test For Ammonia Level. Ammonia in the blood above a certain quantity is a condition called hyperammonemia. This is a potentially dangerous condition and is a result of the liver not functioning properly or because of a crucial enzyme deficiency. The test is done via a blood sample. Usually, an ammonia blood level test hepatic encephalopathy can indicate hepatic encephalopathy or liver cirrhosis. The reason for this is that ammonia is a toxic substance to the human body and because of this reason it is usually converted to urea in the liver for safe excretion.
