Oral fluid testing offers many advantages for drug testing when the possibility of recent drug usage needs to be determined. Oral fluid samples are easy to collect and are non-intrusive. This type of testing is exceptional for critical situations, such as on-site collecting when a lavatory is unavailable or when urine specimen adulteration or substitution is suspected. Test results are typically available within 24 to 48 hours.
Oral fluids drug testing detects the SAMHSA-5 drug panel, marijuana, cocaine, opiates, and amphetamines/methamphetamines including Ecstacy and PCP. These are the most commonly tested drugs of abuse in the workplace. Additional drug tests include oxycodone, barbiturates, methadone, benzodiazepines, K2/Spice, and bath salts.
Oral fluid samples are first screened in the laboratory using a proven and reliable technology called enzyme immunoassay (EIA). Any sample that screens “positive” is then subject to liquid chromatography/mass spectrometry/mass spectrometry (LC/MS/MS). This is the latest technology available.
