Clinical Significance

The biological function of cholinesterase is unknown. Serum cholinesterase serves as an indicator of possible insecticide poisoning. In preoperative screening, cholinesterase is used to detect patients with atypical forms of enzymes and hence avoid prolonged apnea caused by slow elimination of muscle relaxants. Depressed cholinesterase levels are found in cases of intoxication with organophosphorus compounds and in hepatitis, cirrhosis, myocardial infarction, acute infections, and atypical phenotypes of the enzyme.
