What is the Acetylcholinesterase (OP Poisoning) Plasma Test?

The Acetylcholinesterase Plasma Test measures the activity of the enzyme acetylcholinesterase in plasma. This enzyme plays a critical role in nerve signal transmission by breaking down acetylcholine. Exposure to organophosphate pesticides or nerve agents can inhibit this enzyme, leading to toxic effects on the nervous system. This test helps confirm poisoning and monitor response to treatment.

Who should take this test?

• Individuals with suspected organophosphate pesticide poisoning.
• Patients exposed to agricultural chemicals or insecticides.
• People experiencing symptoms like muscle weakness, sweating, breathing difficulty, or confusion.
• Monitoring recovery during treatment for toxic chemical exposure.
• Doctor-advised evaluation in toxicology or emergency care.

Preparation & Test Process

How to interpret results

The test measures the acetylcholinesterase enzyme activity in plasma.

Low enzyme activity may indicate exposure to organophosphate pesticides or nerve agents.
Normal enzyme levels usually indicate no significant toxic inhibition.

Results should always be interpreted by a healthcare professional, especially in suspected poisoning or emergency situations.
