Methods of Alcohol and Drug Testing

The first method of testing we use is a hair test, which uses 1.5" of hair. This test detects drug use for up to 90 days and is good for detecting a history of drug use. Hair drug testing does not detect drug use until within 7 to 10 days of use. Drugs must be used at least 3 times in that window to cause a positive test. Dye, bleach, shampoo, and limited exposure to smoke do not affect the results of the hair drug test.

The second method we use is a breathalyzer test for alcohol. This test involves the use of DOT-approved equipment. The final method we use is urinalysis, which detects traces of drugs in the urine. Traces of drugs can be found within a short time after using them. Depending on the drug, these traces remain for days or weeks.

Our team can provide urinalysis via a Rapid Screen drug test that offers instant results. However, this test, while FDA-approved, is not DOT-approved. A certified SAMHSA lab should also verify it.

Alternatively, we can have a 100% accurate test complete by a federally certified SAMHSA lab with a specific chain of custody in place. This method is DOT-approved and results will be received within 48 to 72 hours. Get in touch with us today to find out more.
