Can A Random Urrine Test Deact Weed
I want to make a test to check every single drug in my blood like cocaïne or lsd or any drugs else.Are they detectable in blood test or i need another?
Drug test: Hi MarcB, Doctors can order what is known as a comprehensive drug screen which can screen for a number of recreational drugs. Not all drugs show up though and depending on the last date of ingestion, the drug may already be metabolized and excreted and therefore not be detected as well. Best of luck, Dr. Ayman Omar ...Read more
I had a drug test come back positive (swab) for heroine. Can A hair follicle test prove that i have been clean of any substances?
Not necessarily: The only SPECIFIC test for heroin is a test for its metabolite 6-monoacetylmorphine or 6MAM. I am not sure whether this is available in swab form, but the first thing with ANY positive test on a screening test, such as a urine drug screen or oral fluid swab is to do the confirmatory test. If they have not done that, they are not following procedure. There also needs to be chain-of-custody on it. ...Read more
I tested positive for heroin using a drug swab test. Never even seen heroin let alone use. Any ideas what caused this?
May never find out: From time to time, labs make mistakes. Specimens get switched. Technicians make clerical errors. Poppy seeds may have cross-reacted. Or if it's just a swab and there is no second test, a simple false-positive 'for no reason.' a test result cannot have any medicolegal consequence unless it is confirmed by a second test that uses a different chemical principle. ...Read more
Will marijuana be flushed out and will i pass a drug test in 19 days after consumption? I rarely smoke. (on a random occasion, meaning not a lot)
Yes: Occasional marijuana use will result in positive tests for generally 2-3 days at most. If you are truly using marijuana on rare occasions and "not a lot, " the test should be negative 19 days later. However, if you are subject to random drug testing, and you continue to smoke, you need to re-evaluate its importance in your life compared with the importance of the reason you are being tested (job). ...Read moreSee 1 more doctor answer
What causes a false positive on an EtG screening test? I have a weekly urinalysis that tested positive for alcohol this week but I did not drink, use any OTC medicine, or mouthwash.
I might have a drug test in 5 days I smoked marijuana today is there anYway I can get clean it is a urine drug test?
It depends: if you only took one it it may not be enough to test. If you have smoked on other occasions recently or smoked a fair amount today there is no way to get it out of your system. If fairly regular use it will take 4 - 6 weeks of sobriety to clear. ...Read more

please tell me if i had cocaine 1 week before the drug tests and weed daily until 2 weeks before the tests , what can I do to pass? It is a preemployment test , is that a urin test or can be saliva etc? Many thanks
Stop usage: Although i'm sure i'd be wasting my breath telling you to quit these habits as they are not healthy, self destructive and...Expensive. With that being said...You need to stop using or even inhaling (pot smoke) for at least4 weeks. It is not only blood, urine & saliva test you need to worry about..Many employers are now also demanding hair samples. And the stuff you use, remains for a long time. ...Read moreSee 1 more doctor answer

Smoked marijuana in jun2013 for 5 days and twice in Oct2013. I have to take a drug test in a week.. Can it be detected in urine or hair follicle test?

Here's a link. http://marijuana.com/drug-test/detection-time/ Stay clean since it matters. Good luck. Perhaps someday this will be a thing of the past. One can hope. Till then, one must be smart. ...Read more
I have taken 4 urine drug test.. I do not use drugs. My urine came straight from me into the cup, what would cause this?
What could cause me to test positive for methamphetamine and amphetamine on a urine drug test that was confirmed using gc-ms when I do NOT use drugs?
What DO you take?: Someone else's specimen may have been mislabeled as yours. Or, you may be taking a medication that is "cross-reactive" with amphetamines and caused a false-positive result. Labs usually include such cautionary information in their reports. Go over the lab report and your meds with the ordering physician. ...Read moreSee 1 more doctor answer

Is there a urine test to check soley for neurontin (gabapentin). I did a 10 panel urine screen, can they pull urine out of the scrn that i did or a diff one, help!
See answer: Since Neurontin (gabapentin) is not a controlled substance nor it is an addictive drug it is not tested for unless there is some specific reason to test for it. A 10 panel drug screen tests for cocaine, amphetamines, methamphetamines (meth), marijuana, methadone, opiates, phencyclidine (pcp), barbiturates, benzodiazepines, and tricyclic antidepressants. ...Read more
