Description

The cholinesterase test measures enzyme levels to assess nerve function and detect organophosphate poisoning or liver disease, with costs typically ranging ¥8–¥30 at hospitals across China; ChinaMedicalHub assists with booking and interpreter support.

Main Uses

Cholinesterase testing is primarily used to diagnose and monitor exposure to organophosphate and carbamate pesticides, which are commonly found in agricultural settings. It is also useful in assessing liver function, diagnosing atypical pseudocholinesterase deficiency before anesthesia, and monitoring the effectiveness of treatment in patients with known exposures or deficiencies.

Normal Range

The normal range for cholinesterase (ChE) levels in blood is typically between 5,400 to 12,000 units/L for total ChE and 3,150 to 6,500 units/L for acetylcholinesterase (AChE). These values can vary slightly depending on the laboratory and the specific method used.

Low Values - Possible Causes

Possible causes of low cholinesterase levels include: organophosphate or carbamate pesticide poisoning, liver disease such as cirrhosis, malnutrition, chronic infections, and certain genetic disorders like atypical pseudocholinesterase deficiency.

High Values - Possible Causes

High cholinesterase levels are less common but can be associated with: pregnancy, obesity, use of certain medications like oral contraceptives, and conditions that increase the production of cholinesterase by the liver. In some cases, high levels may also be seen in individuals with a history of smoking.
