This is Dr. David

what type of pump have you been put on?

pain pumps can give you opiates and narcotics which can test positive.

what type of test did you have done? a urine tox screen test for opiates?

what was positive?

Expert:  DrRussMd replied 1 year ago.


There would be no false positive for hydrocodone.

It is not a standard panel drug, and would be tested for specifically.

If positive, they would send the sample for GC/MS confirmation, which clears up any false positive.


This leaves that you had hydrocodone, or they mixed up patient samples.

I was the first doctor to help you.

sorry for the interuption.

what sort of pump are you on.

there are specific urine tests for hydrocodone in the urine.

even after a week, specific urine tests can still detect small amounts of hydrocodone in your urine if you have been on it before.

what level was detected in your urine?

Expert:  DrRussMd replied 1 year ago.


The urine detection time for hydrocodone is typically 3 days.

Even stretching things, it would not be in your urine if you completely stopped over a week ago.

You need to question the lab on what they tested for, and how.
