What does cholinesterase testing of the blood indicate?

Cholinesterase testing of the blood is specifically designed to measure the activity of the cholinesterase enzyme, which is affected by exposure to certain pesticides, particularly organophosphate and carbamate insecticides. When a person is exposed to these chemicals, the enzyme activity can be inhibited, leading to a decrease in the level of cholinesterase in the blood. This decrease is indicative of the pesticide's effect on the applicator's body, highlighting the extent to which the pesticide interferes with normal nervous system functions.

Monitoring cholinesterase levels is a critical aspect of ensuring that applicators are not experiencing toxic effects from pesticide exposure, making it a valuable tool for evaluating their health relative to pesticide application. The results of such testing can inform safety practices and the need for further medical evaluation or intervention.
