Order Opiate Screen and Confirmation, UrineThe Opiate Screen and Confirmation, Urine is a laboratory test that detects and verifies the presence of opiate compounds in a urine specimen.

About Opiate Screen and Confirmation, Urine in El Monte
A two-step approach to opiate detection in urine.
The screening phase uses an immunoassay designed to flag urine samples that may contain opiates or their metabolites. Because immunoassays rely on antibody binding, certain unrelated compounds can occasionally produce a reactive result, so a reactive screen is not by itself a confirmed finding.
When the screen is reactive, the sample proceeds to confirmation, typically by gas chromatography-mass spectrometry or liquid chromatography-mass spectrometry. These methods separate and identify specific compounds by their chemical properties, allowing the laboratory to report which opiates are present and at what approximate concentration.
Urine is the specimen type for this test. Collection follows standard laboratory procedure, and the test is used in clinical, employment, and monitoring contexts where objective documentation of opiate exposure is needed. Turnaround is typically one to three business days, depending on whether confirmation is required.
