Why This Biomarker Matters

Low levels indicate poisoning from organophosphate pesticides or nerve agents. This test is critical for occupational safety monitoring and diagnosing acute or chronic toxic exposure.

Overview

Red blood cell cholinesterase is an enzyme that breaks down acetylcholine, a neurotransmitter. This test detects exposure to organophosphate pesticides or nerve agents that inhibit this enzyme. Low cholinesterase levels indicate poisoning or exposure to these toxic substances, causing symptoms like muscle weakness, excessive salivation, and difficulty breathing. This test is the preferred method for detecting chronic organophosphate exposure and is used in occupational health monitoring and poisoning investigations.
