What is more effective in screening for drugs a hair follicle urine or blood drug test?
It depends on what information is needed. Hair tests can give a longer history of drug use than urine or blood. Urine tests can detect certain substances from anywhere to several hours or up to a month after use. Blood tests show what substances are currently active in the bloodstream and in what amount. Also, there are many types of urine drug tests, some more accurate than others. Most of the urine tests that are used for employment and for law enforcement (including court officer testing) have a a larger margin for false negative and false positive than is common knowledge.
What can cause a false positive for ecstasy in a urine test?
I recently was switched to Vyvanse from Addarral for adult ADHD and I also see a pain management Dr. for my back which I receive injections for periodically as well as receive pain medications for. The Dr. is informed by me on ALL medications I take on a regular basis and the Dr. tests my urine periodically. On my visit to the Dr. yesterday I was told that my urine tested positive for Ecstacy from my prior visit last month (first urine test since the switch to Vyvanse) As being I am 44 years old and obviously not a recreational drug user the Dr. was aware this was a false positive. So to answer your question. THIS IS ONE OF THE DRUGS that test positive for Ecstasy!
Can certain illnesses give you a positive pregnancy test result if you aren't pregnant?
I am assuming you are referring to a urine pregnancy test which tests for Beta hCG. There are also blood tests, which are more specific, for pregnancy. The urine beta hCG test may be positive for other reasons than pregnancy. Certain cancers of the testicles and the ovary are diseases that can provide a positive pregnancy test. Also, a lot of blood or protein in the urine can give a false positive on a pregnancy test. There are also some medications that have been reported to cause false positives such as some anti-convulsants and anti-parkinson medications. Overall, though, the urine pregnancy test is very accurate. Any female who tests positive on a urine pregnancy test should arrange for an appointment to see a physician for follow-up.
What is a false-positive?
A false-positive is a test result which incorrectly indicates that a particular condition or attribute is present. False-negatives can also occur.
Can you pass a urine test when they use the sticks they dip in the urine?
The sticks worry me greatly. They produce false negatives fairly easily if the tester isn't using an "adulterants" stick--if the subject dumps some Urine Luck or something into his sample the test is real easy to fool. OTOH, they also produce false positives. If you take a lot of Motrin, you can come up positive for pot.
Could excedrin cause positive for THC in urine analysis?
Yes! Your UA test may come back positive with the use of Excedrin. Moreover, the use of Motrin, Advil, and other pain relievers may come back as false positives also.

Can nexium cause false positive for benzodiazepine?
There is no scientific proof that Nexium (esomeprazole) can cause a false positive. The only medication that has been studied and is known to cause a false positive is oxaprozin (Daypro) which is an NSAID. Valerian root is also believed to be a culprit, but once again there is no proof.
Can a child fail a drug test by just being in the same room as people smoking it?
As far as I have been trained as a drug counselor, a person has a 4% chance of failing a drug test from a false positive. There are several medications that will also allow a drug test to be positive, including Advil and some antibiotics. All labs are required to save the urine or saliva swab for 30 days and a re-test can be requested. It is not possible for a false positive to come back wrong twice. The test will also show levels so if a person believes they have a false positive from being in the same room, the level should be very low.
Are there any other drugs that yield the same metabolites as PCP which will cause a false positive on a urine drug test?
The anti-depressants Effexor XR (venlafaxine) as well as it's sister Pristiq (desvenlafaxine) are both capable of causing false PCP positives on urine screens. More common OTC drugs that could be to blame include Ibprofen, which is widely known to metabolize into your urine as Phencyclidine (the main chemical in PCP). Phenhydramine, and dextromethorphan (cough syrup) also work the same way. All of which are in most OTC cold/allergy medications. I work with DISA, Inc. which is a drug screening center for employment. In towns where PCP as a street drug is very uncommon, we often dismiss the positive testing of PCP as a false positive.
