How Drug Test Kits Work?

Drug test kits work by detecting the presence or absence of specific drugs or drug metabolites in a person’s body fluids or tissues, such as urine, saliva, blood, or hair. The kits use various methods to identify the drugs, including chemical reactions, immunoassays, and chromatography. Depending on the type of test kit and the drug being detected, the kit may produce a visual color change, a line on a test strip, or an electronic signal to indicate the result. Drug test kits are widely used in various settings, such as workplace drug testing, drug treatment programs, and sports drug testing.
