How does the detection window for Intercept® Oral Fluid Drug Testing compare with other methods?
Just like traditional urine testing, the window in oral fluid testing is different for each drug. Oral fluid testing identifies recent usage – during the first four hours after drug use – that can be missed by urine testing. For most drugs, the window of detection in oral fluid is about one-to-three days. By contrast, urine testing relies on drug metabolites retained in the body’s waste supply and may detect some drugs for a longer period. Oral fluid testing results are comparable to urine testing results. • What methodology do you employ? Oral fluid samples are screened in our laboratory using enzyme immunoassay technology, proven reliable for routine drug testing. Any samples that test positive in the screening process are then subjected to Gas Chromatography / Mass Spectrometry / Mass Spectrometry (GC/MS/MS), the latest in drug confirmation technology. This tandem “MS” provides the most sensitive fingerprint of the drug target available. • How is the data reported? As with all labor
