Cholinesterase Test

Cholinesterase test measures the level of two enzymes in the blood called acetylcholinesterase and butyrylcholinesterase. These enzymes are responsible for breaking down a neurotransmitter called acetylcholine, which is important for muscle movement and cognitive function.

Pre-test preparation:

There is no specific preparation required for a cholinesterase test.

Testing method:

The cholinesterase test is a blood test. A healthcare provider will take a sample of blood from the patient’s arm, usually from a vein in the elbow or the back of the hand. The blood sample will be sent to a laboratory for analysis.

Symptoms for prescribing this test:

Cholinesterase test may be ordered if a person has symptoms such as muscle weakness, twitching, or difficulty breathing, or if they have been exposed to certain chemicals or drugs that can inhibit the activity of these enzymes.

Diagnosis:

Cholinesterase test results can be used, along with other tests, to diagnose and monitor certain conditions such as organophosphate pesticide exposure, myasthenia gravis, and some types of cancer.

Reference range and normal values:

The normal range for cholinesterase levels in the blood varies depending on the type of cholinesterase and the laboratory that performs the test. Typically, the normal range for acetylcholinesterase is between 8,000-18,000 U/L and for butyrylcholinesterase is between 30,000-100,000 U/L.
