Overview


What is Pseudo-Cholinestrase?

The Pseudocholinesterase test is performed to identify people who have an inherited deficiency of serum cholinesterase or pseudocholinesterase. It Is also performed in combination with other tests to detect a liver disorder, and to confirm poisoning by insecticides containing organophosphates.


Why is Pseudo-Cholinestrase done?

The Pseudocholinesterase test is performed when a blood relative has been previously diagnosed with pseudocholinesterase deficiency identified by a long period of apnea when a succinylcholine based anesthetic is used during surgery. It is also performed if symptoms of organic pesticide poisoning appear, and in case of liver disorder symptoms.
