Normal blood ammonia levels in adults range from 20 to 50 μmol/L or less than 26 to 30 μmol/L. [2] [3] [4] There is at present no clear scientific consensus on the upper limits of ammonia levels for different age groups. [4]
This may also be called standard range. In contrast, optimal (health) range or therapeutic target is a reference range or limit that is based on concentrations or levels that are associated with optimal health or minimal risk of related complications and diseases. For most substances presented, the optimal levels are the ones normally found in ...
Ammonia nitrogen: 1-2 × 10 −6: 1.0-4.9 ... normal range 2-62 × 10 −9: chronic poisoning ... Maintain calcium and phosphorus levels
These missing or reduced enzymes make the process less efficient, allowing ammonia to build up in the bloodstream. High ammonia levels are toxic to the brain, causing a range of physical, neurological, and behavioral symptoms. UCDs can strike at any age.
This ammonia primarily exists as ammonium ion that has a concentration less than or around 35 μmol/L in normal referenced serum levels. [3] Excess ammonia is processed in the liver through the urea cycle to produce urea. [3] Excess ammonia can be produced by bacterial hydrolysis of intestinal compounds, purine nucleotide cycles, the ...
The flammable range of ammonia in dry air is 15.15–27.35% and in 100% relative humidity air is 15.95–26.55%. ... Ammonia is important for normal animal acid/base ...

The normal serum creatinine (sCr) varies with the subject's body muscle mass and with the technique used to measure it. For the adult male, the normal range is 0.6 to 1.2 mg/dl, or 53 to 106 μmol/L by the kinetic or enzymatic method, and 0.8 to 1.5 mg/dl, or 70 to 133 μmol/L by the older manual Jaffé reaction.
