False Positive On Drug Test For Methamphetamine (Page 2)

Hi, i am voluntarily drug testing for CPS because my daughter's father (who had physical custody) passed away suddenly due to a motorcycle accident leaving her "without a legal guardian" I have a previous history of using Methamphetamine. I am clean now or so i thought. Yesterday my test apparently showed positive for Methamphetamine. I know i haven't used. So far i have only came up with two possible explanations.

1. I just had to serve my ex boyfriend with a domestic violence restraining order. To make a long story short, not thinking, I ate some fast food that he insisted on leaving for me. And the 2nd being a cold medicine that I just remembered. I took one pill approximately 2 maybe 3 days ago called ST. JOSEPH DECONGESTANT-FREE HBP. Is it possible that this medicine caused a false positive? Thanks in advance for listening and any insight.

A hair drug test is meant to show consistent use over time. A 1.5 inch sample taken from the scalp will go back approx 90 days. When you had the urine test done at TASC if it was a urine dip test like the ones you buy at the store they should have sent the remaining urine to a lab for GC/MS confirmation testing. GC/MS testing is the "gold standard" for drug testing and most likely would have been negative if you are telling the truth about any METH use. Agencies like TASC sometime get lazy and don't want to do the proper thing when it comes to procedure matters. I am in the drug testing business and tell people all the time that you cannot make a comparison between urine drug testing and hair drug testing. They are two completely different types of testing. Urine testing gives a short history of use, hair drug testing gives the longest history of drug use.

I work in a hospital lab. Adderal is amphetamine and will give a positive response for the amphetamine test. Adderal is also very close structurally to methamphetamine and if present can cause a false positive test for methamphetamine. We have seen this in our lab. The "screening" drug screen tests often cross react in this case and the only way to sort it out is to send it to a more sophisticated lab to be tested by Gas Chromatography/Mass spectroscopy which can tell the difference between amphetamine and methamphetamine. Usually the tested specimens are only saved for a few days so it may be too late to retest the original specimen.

Exomped, i am in a horrible situation because of a fase positive for methamphetamine. I had a cesarean section last month and was given medication that was confirmed by the doctor to cause false positives. My sons stool was tested and also was a false positive for methamphetamine. The hospital new they were at fault and didn't call cys(children youth services) , but my sons pediatrician did call cys even though he confirmed with my obgyn and a childrens doctor at the hospital that it was a false positive. Cys is investigating, they dont belive me and said he will call them and i signed a release for all medical records. I am mortified and upset they gave me that medication and to begin with, and now i could lose my children. I do not use drugs, i wouldn't even think of risking my children. Cys is treating me like a addict. Made me take one of the ez tests where you pee in the cup and its all setup for he results to come out. It of course was negative. The guy still doesnt belive me, he doesn't belive in false positives and said i used meth so i need to deal with the consequences. If you have advice or a helpfull opinion please reply, im scared, worried and i know i couldnt live without my children.

You might seek out the help of an MRO. A Medical Review Officer is a doctor trained to tell why a person might get a false positive. They have an association web site (aamro.com) that you can look for a MRO in your area. The only other thing might be to do your own hair drug test which would prove you aren't addicted to methamphetamine.

Adderall is amphetamine so it correctly should give a positive for amphetamine and would not be considered a "false" positive. Adderall is not methamphetamine but is closely related and many of the "screening" assays performed in the workplace or as the first line testing in a hospital will will give a positive result for methamphetamine test due to its reactivity with the amphetamine (Adderall) if the level is high. The manufacturers instruction sheet details at what level of amphetamine you will start to see false positives for the methamphetamine test. They recommend all positives should be verified by another test called gas chromatography/mass spec (GC/MS). This second test is often only performed at large toxicology labs and the initial testing lab has to send them away to get this testing done at significant additional cost. This testing can sort out whether the methamphetamine result is correct (true positive) or is possibly due to cross reactivity with amphetamine(false positive) or some other substance that is not methamphetamine. Any good testiong protocol should include verification of the initial test by the GC/MS test as recommended by the test kit manufacturer. DEpartment of Transportation and the military testing protocols require conmfirmation testing for all positive results as well as review of testing results and patient medications by a "Medical Review Officer" (MRO) who can interpret the test results and make sure faslse positives are identified and notheld against the person being tested.

The only way our hair drug test will detect adderral is if the sample skips the screening process and goes straight to confirmation (GC/MS). The cost to do complete screening and GC/MS confirmation is less than eight dollars. If the normal hair drug testing process (screening then GC/MS if necessary) adderral won't show up in the AMP category. She definitely needs to consult with an MRO.

My son has been wearing a drug patch for almost eight weeks and also doing medtox urinalysis on random call daily determined each morning.

unexplainably, he has consistently passed every urine test but was told today that he has been testing positive on the patch for Meth.

son swears he has done zero drugs for over two months. Assuming something is causing a false positive.....Sudafed, or Tylenol,etc. no prescribed drugs at all.

is a hair test the way to resolve the discrepancy?

A hair drug test is meant to show consistent use over time. A 1.5 inch sample, cut at the scalp line, would go back 90 days. There are very few false positives using hair testing. You might do a search online for terms like "false positive rates for the drug patch test" and see what turns up. If it was a urine test are you sure they didn't mix up his sample with some other person's sample. At this point a hair test is about the only thing that might give you an indication of what is going on.

One thing to look at is contacting an MRO. A Medical Review Officer is a doctor trained to interpret drug test results and say why something was false positive. You can look up an MRO in you area by checking their association web site at aamro.com. Look for link that say "find an MRO in your area" or something like it.

What county which test place here in imperial county I just busted cps for reporting two false positives. The said my grandson tested pos for morphone in a tezt from october, in jan for morphine and ixycontin

They changed the form the test results were on from one day to next. On tues said "morphone" on wed at court said "morphine"

I went ballistic who changed it?

CPS? County counsel? The lab? The test place cps uses in imperial county is owned by a reserve officer from Brawley.

I fought to get sampples retested they did not want to finally even judge said was fishy so they sent samples to get retestec ar another lab and guess what??THEY WERE NOT POSITIVE FOR OPIATES

My husband is currently on the drug sweat patch. He has been sober approximately 19 months from methamphetamines. His occupation is a roofer. We just found out 3 of 6 of his last tests came back positive for methamphetamine at .2 (the smallest amount needed to set off th test.) Also, note that it was evrry other test and never 2 consecutively. Is there a medically sound way to refute these findings? The courts say positive is positive and he is looking at jail time. We have worked so hard at building s better life, so this is a devastating blow.

In these situations I recommend people consult with an MRO to see what might be causing a false positive. A Medical Review Office (MRO) is a doctor trained to evaluate this type issue (false positives). You can find one by doing a search at aamro.com. Also I would do a search on the internet to find instances of "false positives for the sweat patch". I don't know if the patch is a very accurate way of testing. One of the most accurate way to check for drug use is hair drug testing. I deal with some of the courts in the State of New Jersey and the judge usually court orders a hair drug test. With a hair drug test all screening positives are sent to confirmation using the GC/MS method of testing. Ask whoever is conducting the test if the results were confirmed by GC/MS. If they were not confirmed by GC/MS you might be able to build a greater case for your hubby. GC/MS is the "gold standard" of ALL drug testing. You might look at getting a lawyer who can shoot holes in the use (accuracy) of the sweat patch. Hope I have given you some good insight.

I just wanted to check in and let anyone who was concerned know the verdict. After the cys investigator received my medical records he called me to schedule a meeting. I was scared and panicking because of the horror stories I've read about cys online. I thought he was coming to take my babies away. I was wrong, he came to apologize and close my case. He admitted to marking me as an addict and thinking he would have to put us on a safety plan because of his own uneducated ignorance. He wasn't educated on false positives and thought a false positive for something like methamphetamine was impossible. He looked into it and reviewed my medical records. I was given a certain medication that i still don't know the name of. That medication causes false positives most of the time. He confirmed with someone who is extremely educated about false positives. He told me he plays bad cop\good cop alot and he just happened to be the bad cop when he came to my house. He had to meet my husband and that was it. No further questions, drug tests, check ins, nothing. I am happy to say I was lucky. I had a investigator that truly cared about his job and children's well being. He took the time to investigate even after assuming I was no good. Then he admitted his faults and apologized. My boys are very happy, healthy and they're home, with me. He told me if I would have taken any medication by my own hand, not prescribed or given in the hospital, it would of been a completely different ball game. Thank you for your helpful advice. You gave me a fighting chance and a good back up plan if things had went badly. Thank you for takeing the time to help us mothers in need. :)

You didn't mention if it was a false positive for a urine test or hair drug test so I will assume it is a urine test. If the urine test was a dip test, like you use at home, it might be possible to have more false positives. The "gold standard" of urine drug testing is done by the method of GC/MS lab testing. If the lab didn't use GC/MS testing shame on them. If there is any urine left over from the last test you can insist on a full lab test using GC/MS. Did your girlfriend sign a chain of custody form for the urine test? If she didn't the lab/hospital/company doing the testing might have mixed up her specimen with someone else's specimen. She should have also initialed a specimen seal the should be put on the actual container used to hold the urine specimen. Always get a copy of the chain of custody form. I provide one with every hair drug test.

A hair drug test is meant to show consistent use over time. A 1.5 inch sample of hair, cut at the scalp line, will go back 90 days. There are very few false positives with hair drug testing. My recommendation would be to contact an MRO. An MRO (Medical Review Officer) is a doctor trained to interpret drug test results and say why there might be a false positive. You can look up an MRO at their association web site at aamro.com. You can also do you own hair drug test. It is not all that expensive and the results can be used in a court proceeding.

Hi. People are so set, she did it I did a 12 panel in home test and she still came up positive would a hair test show she is not guilty of what she is being accused of and we don't know how to go about a retest or where to go.

I'll tell you what I usually tell people who CALL ME with the similar situation and that would be at this point a hair drug test is about your only hope to prove you (she) are not using drugs. It sounds like something they gave her at the hospital caused a false positive. That is why an MRO is good at figuring out what might have caused a false positive for methamphetamine. Most likely she would be negative on a hair drug test because a hair drug test is good at rejecting false positives.
