Industry
Ammonia (NH3) is used in explosives, fertilisers, refrigerants and household cleaning solutions.
Physiology
NH3 is produced in the liver, intestine and kidneys as an end-product of protein metabolism; the liver converts ammonia into urea, which is then excreted by the kidneys; in liver disease this conversion is decreased, resulting in increased serum ammonia. Serial measurement of ammonia is used to follow progression of hepatic encephalopathy in Reye syndrome and other conditions.
Ref range
15–49 µg/dL.
Abnormal values
Increased hepatic coma, Reye syndrome, severe CHF, GI haemorrhage, erythroblastosis fetalis, drugs (e.g., diuretics and antibiotics).ammonia NH3 Physiology NH3 is produced in the liver, intestine, and kidneys as endproduct of protein metabolism; the liver converts ammonia into urea, which is then excreted by the kidneys; in liver disease this conversion is diminished, resulting in ↑ serum ammonia; serial measurement of ammonia is used to follow the progression of hepatic encephalopathy in Reye syndrome and other conditions Ref range 15-49 µg/dL Abnormal values ↑ Hepatic coma, Reye syndrome, severe CHF, GI hemorrhage, erythroblastosis fetalis, drugs–eg, diuretics and antibiotics.
