The target analyte for the standard opiate drug test is morphine, which high dose oxycodone use has been reported linked to positive results.
i hadn’t had an oxy in 28 days, so how did my urine test positive?
Hydrocodone and oxycodone remain the most detected prescription opiates the general U.S. work force, and random drug tests for the two.
"The use and misuse of prescription opiates continue to capture national attention," said Dr. Empowering employees to perform duties safely, act appropriay when they perceive risk, and understand clearly the consequences of non-medical use of these drugs and of being found to have violated their employer’s drug policy all play an important role in worker and public safety.". Barry Sample, Quest Diagnostics director of Science and Technology for Employer Solutions. "The findings of this study reinforce the need for businesses to develop and communicate clear policies around both the medical and non-medical use of these drugs, especially for their safety-sensitive workers.

ABSTRACT Opiate testing for morphine and codeine is performed routinely in forensic urine drug-testing laboratories in an effort to identify illicit opiate abusers. In addition to heroin, the 6-keto-opioids, including hydromorphone, hydrocodone, oxymorphone, and oxycodone, have high abuse liability and are self-administered by opiate abusers, but only limited information is available on detection of these compounds by current immunoassay and gas chromatographic-mass spectrometric (GC-MS) methods. In this study, single doses of hydromorphone, hydrocodone, oxymorphone, and oxycodone were administered to human subjects, and urine samples were collected before and periodically after dosing. Opiate levels were determined in a quantitative mode with four commercial immunoassays, TDx opiates (TDx), Abuscreen radioimmunoassay (ABUS), Coat-A-Count morphine in urine (CAC), and EMIT d.a.u. opiate assay (EMIT), and by GC-MS. GC-MS assay results indicated that hydromorphone, hydrocodone, oxymorphone, and oxycodone administration resulted in rapid excretion of parent drug and O-demethylated metabolites in urine. Peak concentrations occurred within 8 h after drug administration and declined below 300 ng/mL within 24-48 h. Immunoassay testing indicated that hydromorphone, hydrocodone, and oxycodone, but not oxymorphone, were detectable in urine by TDx and EMIT (300-ng/mL cutoff) for 6-24 h. ABUS detected only hydrocodone, and CAC failed to detect any of the four 6-keto-opioid analgesics. Generally, immunoassays for opiates in urine displayed substantially lower sensitivities for 6-keto-opioids compared with GC-MS. Consequently, urine samples containing low to moderate concentrations of hydromorphone, hydrocodone, oxymorphone, and oxycodone will likely go undetected when tested by conventional immunoassays.
