Test Details: A qualitative urine test for opiates is performed in suspected overdose cases or as part of a drug of abuse program. This test is also useful for follow-up testing of a presumptive result and for confirmatory testing by mass spectrometry. Opiates in general are a group of drugs commonly referred to as narcotics, that are used medically to relieve pain, but that also have a high potential for abuse. Morphine and codeine are found in the resin collected from the opium poppy.
