What is Cholinesterase Test?

The Cholinesterase test is a blood test to measure the activity levels of Cholinesterase enzymes in the body. The Cholinesterase test is performed to diagnose an inherited pseudocholinesterase deficiency and to detect organophosphate pesticide exposure, which inhibits Cholinesterase activity.
