Urine Drug Testing

LabCorp is an industry-leading provider of urine drug testing services.

Our Substance Abuse and Mental health Services Administration (SAMHSA)1-certified laboratories conduct urine drug analyses in accordance with Department of Health and Human Services2 and Department of Transportation3 requirements. Testing of nonregulated specimens is conducted using comparable stringent protocols.

Our strategically located laboratories offer a full range of testing services and provide prompt turnaround times nationwide. Uniform laboratory processes and a single computer platform provide standardized reporting regardless of testing location. 

Standard urine drug testing panels range from five to 10 drugs. Specimen validity testing is available to detect adulterants or specimen substitution resulting from a donor’s attempts to mask drug use. Expanded profiles for medical professional monitoring are also available.

The Drugs of Abuse Reference Guide provides common drugs of abuse that may be included in a urine drug screening panel. LabCorp encourages the use of an independent medical review officer (MRO) to review all non-negative test results. Information contained in the Drugs of Abuse Reference Guide is to be used as general guidelines only. Many variables may affect duration of detectability, such as drug metabolism and half-life, subject's physical condition, fluid balance and state of hydration, and route and frequency of ingestion.
