Greetings posters,I am set to take my first drug test for my nursing program in nine to eleven days. I took 4mg klonopin 3 days ago and had been taking it occasionally-not daily-for a couple weeks. I am somewhat confident that I can pass a regular urine dip immunoassay test, but I am not certain what sort of test is used in situations where a lab is subcontracted to perform the work.Are mass spectrometry/gas chromatography tests the exception rather than the rule? I know they are used to confirm a positive result but I think that for a small young man who exercises, 12-14 days will be enough to get the drug out of my system. I hate to ask a question like this and am well aware of all the disappointment it evokes on other posters on this forum. So I apologize in advance for asking.
