A Comparison of Oral Specimen Collection and Laboratory Urinalysis Among Baltimore City Arrestees

Oral fluid testing to assess recent drug use is compared to laboratory urinalysis for sensitivity and specificity. The authors also interview arrestees on this less invasive method. With laboratory urinalysis as the reference model, the oral collection device was 95 percent sensitive and 98 percent specific for cocaine and 90 percent sensitive and 99 percent specific for opiates.
