I took metformin 500 mg and I was wondering how long after stopping that it was out of your system and could it cause a false positive drug test?

I took metformin 500 mg and I was wondering how long after stopping that it was out of your system and could it cause a false positive drug test?

Metformin 500: Metformin 500 is usually taken twice a day — out of your system every 12 hours.

I don't think it can cause a faulse positive test if you are monitoring your blood sugar.

If you think the metformin associated blood glucose values are too high or too low please contact your doctor. ...Read more

Can you suggest foods that trigger 'false positive' drug test results?

Can you suggest foods that trigger 'false positive' drug test results?

As far as I know,: The only food that can cause positive results in urine (and other) drug testing is poppy seeds. This is actually not a false positive, because poppy seeds do contain very tiny amounts of a chemical related to morphine, papaverine, which is metabolized into morphine. I am not aware of any other food that can do this. They are found in pastries, bagels and other baked goods. ...Read more

How much time does it take a drug test to come back a false positive?

Dont understand ?: Most tests are "screening" tests, and results from those can be available instantly on some tests — within seconds or minutes — or have to be sent to a lab where it is 1-2 days, depending on their volume, whether it comes on a friday before a 3-day weekend etc. If tests are positive, confirmatory tests are done and may take additional 1-3 days. If those are positive, they are usually NOT false +. ...Read more

Many screening tests will detect a variety of amphetamine like substances — metabolites of ephedrine, (ephedrine sulfate) Pseudoephedrine or others of the substituted phenethylamine group — a very large group.

What to do if I had a false positive on a drug test, is there a chance I'll still get hired?

Not if they think it: Is positive. Companies that operate ethically should have a drug testing policy that requires confirmation of any positive on a screening test. The confirmatory tests, at this state of their development, DO NOT HAVE false positives. If you tested positive, and they confirmed the test with a sophisticated method the way they should, it means YOU USED THAT SUBSTANCE. So I would say stop using. ...Read more

Can vitamin B2 cause a false positive on a drug test?

Can vitamin B2 cause a false positive on a drug test?

No: I thought this was a strange question, but in researching it found out that this is claimed on some websites. However, I am quite certain that b2 does not cause a false positive on drug tests. It can make your urine bright yellow & some who drink a lot of fluids to dilute their urine before a test will sometimes take b2 so the urine looks yellow rather than clear. Will not cause false positive. ...Read more

Does gabapentin cause a false positive on a urine drug test?

Does gabapentin cause a false positive on a urine drug test?

Not Likely: It is unlikely that Neurontin (Gabapentin) will trigger a false positive urine test for drugs. However, if you are taking other medications then these medication may alone or in combination with Neurontin trigger a positive urine screen. Also, poppy seeds and other foods, fermented or otherwise may result in positive screen. Here's a reference: http://dig.pharm.uic.edu/faq/2011/Feb/faq1.aspx ...Read more

Can amoxicillin cause a false positive for cocain on a drug test?

No Proof: The only medical trial to test this was done in on 33 Amoxicilin pts in 2008 and no false positives were found: http://jat.oxfordjournals.org/content/32/4/315.full.pdf

Contrast this with the thousands who claim this to be true on the net and we have a dilemma.
