The Testing Process

Over 75% of drug testing performed in the United States is lab-based urinalysis testing. The test process begins when a donor gives a urine sample at a laboratory owned or approved collection site. The collector sends the sample overnight to the laboratory to undergo an emit screen (immunoassay analysis) or enzyme immunoassay (EIA). If the initial test is non-negative, the samples goes for further testing by gas chromatography/mass spectrometry (GC/MS) to confirm the result.

Once a test result is determined by the lab, it is sent electronically to a Medical Review Officer (MRO) where it is reviewed for accuracy and completeness.  Matrix ESS works with National Medical Review Corporation, Dr. John Eustace, MD to provide MRO services.  Dr. Eustace is a licensed physician with expert knowledge of substance abuse and is certified by the American Association of Medical Review Officers (AAMRO).  Once the results are reviewed by the MRO, they are reported directly to our client company via e-mail, secure web access or fax.
