Calloway's drug testing protocols include high volume urine screening for results within 24 hours. Our screening technology can identify any of 17 drugs, making it one of the most comprehensive portfolio available. We customize this list for each physician depending on the individual requirements of the patient base.

Our screening menu includes oxycodone (Oxycontin®, Percocet®), buprenorphine (Suboxone®), methadone, opiates, phencyclidine (PCP), THC, propoxyphene, benzodiazepines, cocaine, ethanol, amphetamines, and barbiturates. In addition, specialty screening tests for other less commonly abused drugs are available by request, and all of our reports can be custom tailored to reflect standard or zero tolerance cutoff levels.
