Ammonia serum levels (AMMON)
Ammonia is derived from bacterial enzymatic action on ingested amino acids. It is absorbed from the gastrointestinal tract and delivered through the portal vein to the liver, which converts most of it into urea.
Serum-based tests : 2 ml SERUM. Centrifuge immediately after clotting. Keep at ambient temperature or 4°C for 24h. For longer periods, aliquot, freeze and ship frozen.
Abnormally high levels of ammonia can result from colic or “enteric hyperammonemia” (combination of increased bacterial production and increased gut permeability) that occurs despite normal hepatic function. Hyperammonemia is a metabolic condition characterized by elevated levels of ammonia in the blood. Increased entry of ammonia to the brain is a primary cause of neurologic disorders, metabolic disorders and some toxic encephalopathies.
Please kindly note that for all the tests that are done in our partner labs in the USA, a full prepayment must be received before your sample is sent for testing.
Partner labs demand a full prepayment before the sample can begin to travel. Thank you for your understanding and collaboration.
It will take approx. 4 weeks to get the results from all tests, except for MSA (6 weeks) and CD56 and CD57 (48 -72 hours).
