False Positives for Oxycodone
My son who is in a drug court program is drug tested every thursday. It's always a urine test but was given a saliva test a few weeks ago and it showed a trace of oxycodone. He has been clean over 500 days and is adamant about it being a mistake. He had a hair follicle test performed but the court won't accept it because it supposedly only shows chronic use, not a one time use. Wondering if anyone knows of anything that could cause a false positive for oxycodone or have experienced a lab mix up?

Ive heard of false negatives for Oxycodone.

Standard Drug Tests Sometimes Miss Oxycodone

Another problem is that most standard drug tests have a substantial false-negative rate for oxycodone (OxyContin, Percolone, Roxicodone) an opioid drug that's been associated with high levels of abuse. In some cases, a person could be taking oxycodone and the routine drug screen may miss it and report as negative. Oxycodone is also found in the medications Percocet, Roxicet, and Tylox.

Yet one study in the review showed that 88% of doctors didn't know that they may need to order a special test to accurately screen for oxycodone.
