Cholinesterase - blood

What is Cholinesterase Testing?

Cholinesterase testing is a lab test that measures the amount of particular enzymes, known as cholinesterase, in the bloodstream. Cholinesterase is an enzyme found in all cells, including the red blood cells. It is responsible for breaking down a number of different substances, including certain types of drugs, toxins, and pesticides. When cholinesterase levels are too low, it can be an indication that there is an underlying health condition present.

Preparation for Cholinesterase Testing

There is no special preparation required for cholinesterase testing. It is important to inform your doctor if you are taking any medications, vitamins, or supplements as they may interfere with the accuracy of the results.

Procedure for Cholinesterase Testing

Cholinesterase testing is fairly simple and is performed by drawing a small sample of blood from a vein in your arm. The sample is then sent to a laboratory for analysis. The results will be available within one to two days.

Types of Cholinesterase Tests

There are two types of cholinesterase tests, AChE and BChE. AChE, or acetylcholinesterase, is the most commonly tested. BChE, or butyrylcholinesterase, is tested less often.

Why is Cholinesterase Testing Done?

Cholinesterase testing is commonly done to help diagnose certain medical conditions and to monitor the effectiveness of treatment plans. It can also be done to determine if a person has been exposed to certain types of toxins or medications. It can also help monitor the effects of organophosphate poisoning, which is a type of poisoning caused by certain insecticides and other chemicals.

When is Cholinesterase Testing Done?

Cholinesterase testing is done when a doctor suspects that a patient may have an underlying medical condition or has been exposed to certain toxins or medications. It is also done to monitor the effectiveness of treatments. Additionally, it is done to monitor the effects of organophosphate poisoning.

Risks of Cholinesterase Testing

The main risk of cholinesterase testing is minimal pain or discomfort at the puncture site. There is also a small risk of infection from the needle puncture. In rare cases, serious complications may occur. However, these risks are very low.
