Hello, this is Dr. David. I have read your question and I'm ready to help.
a 9 panel urine tox screen tests for Amphetamines Barbituates Benzodiazepines Cocaine Opiates Marijuana Methadone. Methamphetamines PCP
so the opiate tests does not differentiate between hydromorphone and hydrocodone.
actually Hydrocodone is metabolized to hydromorphone
so it can be particularly difficult to tell the use of these two drugs apart without specific mass spectroscopy/gas chromatography confirmatory testing.
let me know if you have questions.

HiI am one of the drug testing experts. The above answer is not correctThe drug test initial screen will be positive for opiatesHowever the confirmatory test will differentiate between the two Even though hydrocodone is metabolized into hydromorphone it is not 100 percent converted and so the test will still find the drug I hope this helped Please leave positive feedback for my time and expertise :-)
