Relapses during addiction treatment found after a change in urine drug testing methodologies
Introduction: Definitive urine drug testing (UDT) may provide a more complete picture of a patient’s drug-taking behaviors than presumptive UDT. Definitive UDT involves mass spectrometry, either LC-MS/MS or GCMS, and may not require a screen. In contrast, presumptive UDT, sometimes referred to as screen-first, involves immunoassay, such as point-of-care cups, and chemical analyzers, and may be followed by confirmation of positive results. Substance-use counselors have previously reported that switching from presumptive to definitive UDT helped identify relapses and impacted the quality of counseling, treatment planning, and patient outcomes. However, an objective assessment of new relapses potentially identified when switching UDT methodologies had yet to be undertaken.
