Is there a medical test to show whether Ive been exposed to chlorpyrifos?
There is a general test that can be used to determine if you have been exposed to a certain group of insecticides, including chlorpyrifos. This test measures the activity of an enzyme called acetylcholinesterase in the blood. There is also a test which measures a metabolite, or breakdown product (known as TCP), of chlorpyrifos in the urine. The metabolite TCP can usually be found in the urine for several days after the exposure to chlorpyrifos occurred.
