Laboratory & MRO Services

Labratory Services The complex nature drug screening and its ramifications in the workplace makes choosing a lab critical part of the testing process. Advanced Toxicology Network performs more than 7,000 immunoassay screening tests per day as well as over 800 GC/MS confirmations per day. This volume makes ATN one of the country's largest single site drug testing laboratories. At Southeast Texas Drug Screening we demand as much from our lab as we do from our self, that is why we have chosen to make ATN our lab. MRO Services A MRO (medical review officer) is a licensed physician, independent from the laboratory that is certified and possesses knowledge in the field of substance abuse, pharmacology, and toxicology of drug screening. The MRO is responsible for receiving drug test results, conducting interviews with positive recipients, monitoring drug rehabilitation, return to work testing, and monitoring laboratory performance to insure quality control. Southeast Texas Drug Screening uses Tri-State Independent Medical Examiners for all our MRO needs.
