I am also new here but due to my job I have some knowledge of drug testing. Depending on the type of test ordered hydrocodone is detected from 1- 3 days. Without a suspicion of opiate use it is EXTREMELY unlikely that a Dr. will order a gas chromatagraph type test due to cost. That is the type of test with the longest detection time. Not all of the standard antibody reactive tests used to screen for opiates will even pick up hydrocodone as most of the tests look for morphine and its metabolites. With a 2 day break from hydro the odds are highly in your favor and with 3 days you should be ok regardless of the test used ( excluding hair).
