Critical Value:  
Interpretive Comments: A positive result for the Opiates Screen indicates that the drug (any combination of codeine, morphine, hydromorphone or hydrocodone) may be present in urine at a minimum total concentration of 300 ng/mL. This result is to be regarded as preliminary/presumptive unless subsequently verified by a definitive confirmation test (available upon request by calling the Toxicology Laboratory).

Note 1. The Opiates Screen is a poor screening test for oxycodone, and the result will be positive only when the concentration of oxycodone in the specimen is very high.

Note 2. This is NOT a test for non-opiate opioids (eg: fentanyl).
Special Processing:  
Comments: Please order Urine Oxycodone separately, as the urine Opiates Screen is a poor screening tool for Oxycodone.
