Non-DOT Hair Follicle Drug Testing

Service Description

Hair follicle drug testing is a method used to detect the presence of drugs in a person's system by analyzing a sample of their hair follicles. During the test, a small hair sample is taken from close to the person's scalp. The sample should be approximately 1.5 inches long and as thick as a pencil. This sample is then sent to a laboratory for analysis. Hair follicle drug testing can detect metabolites of drugs, which are substances produced as a result of drug metabolism in the body. This means that it can provide a longer detection window compared to other types of drug tests, such as urine or saliva tests. Hair follicle testing is capable of detecting drug use within the past 90 days, making it useful for detecting chronic or long-term drug use. One advantage of hair follicle drug testing is its ability to provide a historical record of drug use over an extended period. The hair sample retains a record of drug exposure, even after the substances have been metabolized and eliminated from the body. This makes hair follicle testing particularly suitable for cases where long-term drug use needs to be identified.
