Once a urine specimen is received in one of our labs, it is scanned into the system and receives a unique lab accession number of the most reliable identification and tracking. Then, an alliquoted sample undergoes validity testing (as a part of initial testing) using PH values, specific gravity and creatinine to ensure it is a human sample and that it has not been diluted or adulterated. Along with this, the urine sample will be screened for the presence or absence of benzodiazepines, opiates, and other illicit drugs using Diatron P500.
Liquid chromatography – tandem mass spectrometry (LC/MS/MS) is used when optimal specificity and sensitivity are required to determine the absence or presence of your patients prescribed medications as well as the presence of non-prescribed medications or illicits
