Drug Immunoassay Panel, Urine
Use
Detecting drug use involving barbiturates, cocaine, and carboxy‑tetrahydrocannabinol. This test is not intended for use in employment‑related testing and is intended for clinical monitoring or management purposes, not forensic or employment screening. Tests are screening assays followed by confirmation via definitive methods when positive, as part of broader profiles such as CSMPU, ADMPU, or CSMEU.
Special Instructions
Only orderable as part of a profile (e.g., CSMPU, ADMPU, CSMEU). Positive screening results are confirmed and quantitated by definitive methods—GC‑MS for barbiturates and cocaine/metabolites, LC‑MS/MS for tetrahydrocannabinol metabolites—at an additional charge. Ordering guidance indicates it does not screen for drug classes beyond those in the testing algorithm.
Limitations
A positive result indicates recent use of the detected drug but is limited to the specified classes; not for employment testing. Screening is by immunoassay and may require confirmatory testing by mass spectrometry for definitive results; interference or improper specimen handling can cause diagnostic confusion.
