5 Drugs Metabolites – Urine

Our drug testing laboratories are certified by HHS/SAMHSA.
Over 90 laboratories across the USA currently maintain accreditation in this program. Review and grading of both inspections and proficiency tests by a central group ensures that any urine drug screening test performed anywhere in the USA will follow the same procedures and produce the same results. This is perceived by the public as ensuring fairness in the drug screening program.
All substance abuse specimens submitted to the Service Centers are initially tested using a screening technique called Enzyme Immunoasay (EIA).
While pre-employment drug screening is a good practice and a great start to a drug free workplace drug program, it is only the first step in creating and maintaining a drug free, cost effective, highly productive workplace. Random testing, voluntary testing, reasonable suspicion testing, specific condition testing and follow-up testing are all equally important types of drug testing.
In addition to the federally mandated NIDA panel we offer a variety of test panels and cut off levels, which can be combined with adulterant testing. Adulterant testing detects substances (either added to the urine specimen or ingested) that are promoted as “cleansing agents” to prevent the detection of drug use.
