Thank you for your question:

What type of drug test?

Do you know if the test was confirmed with GC/MS (Gas chromatography-mass spectroscopy)?

Why was the test done?

Did you ever use oxycodone?

Were you taking any other medications?

Thank you for the additional information:

If the test was done with immunoassay technology (such as the dipstick or point of collection test), there are a number of medications that can cause false positive. To be scientifically/legally defensible, the test should be confirmed with GC/MS. This technology essentially produces a "chemical fingerprint" of the specimen eliminating the false positive issue.

You should ask to have the specimen confirmed with GC/MS to eliminate the issue of false positives.
