Elevated orotic acid
Elevated urinary orotic acid levels can also arise secondary to blockage of the urea cycle, particularly in ornithine transcarbamylase deficiency (OTC deficiency). This can be distinguished from hereditary orotic aciduria by assessing blood ammonia levels and blood urea nitrogen (BUN). In OTC deficiency, hyperammonemia and decreased BUN are seen because the urea cycle is not functioning properly, but megaloblastic anemia will not occur because pyrimidine synthesis is no… WebWhat does it mean if your Orotic Acid result is too high? Elevations are most commonly associated with ammonia toxicity. Elevated ammonia may result from drug toxicity to the liver, viral liver infection, gastrointestinal bleeding, or inborn errors of ammonia metabolism. Confirmation of a genetic disorder requires testing plasma amino acids.
