I am trying to do some research into how you can have a false negative drug test for Hydrocodone. Can other meds interfere with this urine test? Other medical problems? Can taking Lasix, being diabetic, or blood pressure meds cause this? I just know that the meds are being taken and the urine test came back negative and the Dr was rude and will not give me any answers to why. So if anyone knows how or where I can look into this I would be in your debt. Thank you
I am sorry that this has happened to you. We have several members that have experienced an inaccurate drug screen also. Your physician will not offer solutions. I beleive that they don't know the cause themselves.
The reasons are not clear but it is not an uncommon occurrence. Lasix (furosemide), Hypertensive agents or other medications that do not contain a narcotic cannot produce a false positive or negative drug test. Diabetes will not interfere with the test either.
There are statistics that claim urine drug screens are as high as 60-70% inaccurate. These tests are not fail proof though the company/facility conducting them rely on them to be 100% accurate.
If you find the answer you will be wealthy. It can just be the results of human error as Dalek4 indicated above. There are some articles on the subject. I may have one that I can PM you if you are interested in reading it.
Again I am sorry that this has happened to you. I hope you will not suffer huge ramifications. Please keep in touch.
I too have had a false negative. I had a peak and trough done. In doing this my pain mgmt md had me take my meds in front of him, then they did blood draws in 30 min intervals. I happen to be a rapid metabolizer. After 6 hours the meds were low enough to be undetectable in a urine screen.
