Will taking Zyprexa negatively affect employee drug test results?

I found your blog while trying to find out more about Zyprexa on Yahoo.  I am so mad!  I just found out today that I was just turned down for a job I really wanted because my drug test came back messed up.   Since I'm not taking any non-prescription drugs (yeah, really) and I wasn't drinking alcohol prior to the test, I was thinking that perhaps the Zyprexa I'm currently taking for bi-polar synptoms might be getting 'read' in the blood tests as a controlled substance?  Hell, if poppyseeds can do it, perhaps Zyprexa has something in it that could, as well?  Any help would be appreciated, as I am going to appeal the drug test results with the drug testing clinic on Monday.  I've only been taking Zyprexa for less than 2 months, and I've gained almost 10 lbs and want to sleep all the time.  It would really be crappy if this stupid drug caused the test to read incorrectly.... HELP!!!
