HAIR / URINE TESTING
Hair Testing can detect the past three months of drug use and therefore find a drug user who has stopped for a short time to pass the urine test. There are no known methods for sample adulteration, including hair washing, which does not dilute the sample.
Because it takes approximately a week for ingested drugs to show up in hair above the scalp, a hair test is not the best method to use to find an individual who has just started taking drugs.
DOT lab based urine specimens are sent to a SAMSHA certified laboratory and must be the extended 5-panel test, as required by the Department of Transportation, for employees working in a safety-sensitive position.
Company authority testing can also be accomplished with a lab based urine test.
