How does hydrocdone guaif. syrup show up on a drug test? My employer did a random drug test and it came back positive for Opiates. Is that the same thing? The Testing Panel says 9 panel w/ oxycodone, what does that mean.
Hydrocodone is an opiate, just like Vicodin, Percocet, and Oxycontin will show up as opiates on a drug test. A 9-panel test means they are testing for 9 drugs, most people do a 5-panel test.
