Monitoring exposure to organophosphorus insecticides
Monitoring patients with liver disease, particularly those undergoing liver transplantation
Identifying patients who are homozygous or heterozygous for an atypical gene and have low levels of pseudocholinesterase
This tests is not useful for the differential diagnosis of jaundice.
Pseudocholinesterase (PCHE) testing has two main uses:
-Monitoring for toxic exposure in people who work with organophosphate compounds by establishing a baseline PCHE activity level. Then routine testing is used to monitor for a significant reduction in PCHE activity.
-Preoperative screening for patients with a history or family history of prolonged paralysis and apnea after the use of the muscle relaxant, succinylcholine, for anesthesia
This test can also diagnose acute organophosphate pesticide exposure.
