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.
Interpreting Pseudo-Cholinestrase results
Results are expressed in Units/Litre (U/L). The normal ranges for Pseudocholinesterase in the body are:
• Males: 3,100-6,500 U/L
18-49 years: 1,800-6,600 U/L
More than 50 years: 2,550-6,800 U/L
