About Opiate Screen and Confirmation, Urine in Downey
This test is used when a preliminary immunoassay result needs to be checked against a more definitive analytical technique.
The screening phase uses an immunoassay that reacts broadly to opiates and their metabolites. Because immunoassays are designed for speed and sensitivity rather than absolute specificity, a reactive screen is considered presumptive and is not, by itself, a confirmed finding.
The confirmation phase applies a chromatographic method, typically gas or liquid chromatography coupled with mass spectrometry, to separate and identify individual compounds by their physical and chemical properties. This step distinguishes true positives from cross-reactive substances and can often identify the specific opiate or metabolite present.
Urine is the specimen type because opiates and their metabolites are excreted in urine over a detectable window after use. Collection follows standard laboratory procedure, and the turnaround for the combined screen and confirmation is typically one to three business days.
