Red cell cholinesterase
WebRed Blood Cell Cholinesterase Synonym/acronym: Acetylcholinesterase (AChE), erythrocyte cholinesterase, true cholinesterase. Common use To assess for pesticide toxicity and screen for cholinesterase deficiency, which may contribute to unrecoverable apnea after surgical induction with succinylcholine. Specimen Whole blood (1 mL) collected in a … WebFor organophosphate and carbamate poisoning, see Cholinesterase red cell, which is the preferred test. Interpretation: Susceptibility to 'Scoline apnoea' is inherited as an autosomal recessive disorder; cholinesterase activity is usually, but not always, low. Dibucaine and fluoride numbers improve the sensitivity and specificity of the test.
