Test Methodology

Immunoassay, Gas Liquid Chromatography/Mass Spectrometer (GC/MS), Liquid Chromatography/Tandem Mass Spectrometry (LC/MS/MS).

This test was developed and its performance characteristics determined by Beaumont Health. It has not been cleared or approved by the FDA. The Laboratory is regulated under CLIA as qualified to perform high-complexity testing. This test is used for clinical purposes and should not be regarded as investigational or for research.

Interpretation

Drugs detected by the immunoassay screening procedures represent tentative findings and will be reported as "Unconfirmed positive" and a confirmatory test will be initiated using GC/MS or LC/MS/MS. Acetaminophen and salicylate will not be confirmed. Drugs identified by GC/MS will be reported as "Confirmed positive."

Effective June 4, 2019, the laboratory will no longer automatically perform confirmation testing on positive THC screen in patients 21 years of age or older. If a confirmation is needed, please call the lab to add the test on to the original specimen.

Clinical Utility

This urine screening assay is a broad based chromatographic screen for common illicit, over-the-counter, and prescription drugs. Confirmation of initial findings by GC/MS or LC/MS/MS will follow.
