Yes it is a actual drug that is tested for in the drug test (benzodiazepines) you are taking so it's not so much a false one more as a positive one.
No
No it can not.
No
There are two tests run on a sample: a "screening" test and a "confirmation" test. Naproxen will throw false positives for THC on screening tests, but confirmation tests can tell the difference between Aleve and weed.
medications w/ certain hormones can cause false positives or negatives. and certain pregnancy tests are better than others. i recommend seeing a dr.
Don't take drugs. Also, one might try avoiding substances which can cause false positives on tests.
Yes. the drug is for blood pressure. Some records show positive test. These tests are called false positives.
Benadryl (Diphenhydramine), has been reported to cause false positives for benzodiazepines (such things as Xanax, Valium), PCP and tricyclic anti-depressants. The false positives occur using the screening-type tests (sticks, cups, etc) but confirmatory tests using GC/MS should clear any false positive.
Because they lack specificity and accuracy, their use is limited. False positives can cause emotional distress and fear. It is not yet determined if there is a savings of life or money with testing.
Yes. But it won't save you, because there are more specific tests they can give that do not show false positives.
All such tests have a certain probability of errors, both false positives ad false negatives.
Most cough products which contain decongestants (pseudoephedrine, ephedrine, synephrine, phenylpropanolamine) can cause false positives with methamphetamine drug triage tests. The amount necessary which could cause a false positive depends on the detection sensitivity of the specific analyzer being used (they have different detection thresholds).
Yes, Riboflavin contains vitamin B2, as well as hempseed oil, both of which can create false positives, sometimes as high as 650 ng/mL (the cutoff level for most EMIT tests is 50 ng/mL). Furthermore, Ibuprofen and Naproxen are known for causing the same false positives on these tests as well.
