False Positive On Drug Test For Cocaine (Top voted first)

Updated

I took a hair follicle test and it came up positive for cocaine. I have never used drugs in my life. I have a kidney infection and I have been having trouble with my kidney all my life on and off. I was taking Ampicillin 500mg and Metronidazole 500 mg and Eugenol. I am going to court concerning my kids and I can't lose them for drugs when I never took them before. Please help me. Thank you.

I have had a dental surgery with in the last month. I was received 7 total shots to numb my mouth of some sort of 'cain' derivative. I now have to submit to a hair follicle test with in the next week. Is it possible for me to have a false positive and should I take a letter from the oral surgeon stating exactly what he gave me?

I am in a battle for my kids. My ex made a false report and to my surprise my baby tested positive for cocaine in her hair. She was in the NICU for the first week of her life. She has never had a hair cut as she hardly has any hair. I also have submitted a hair test but don't know the results yet. Although I am on several of the medications I've read that has caused false positives on this blog. I am scared to death. I haven't used in almost 7 years. I used before I had 3 kids and why would it be in one and not my other 3 kids if I was using. I am praying to find the answers to prove these people wrong. I haven't used drugs in years and if I did it sure in the hell wouldn't be around my kids!

I tested positive on a blood test for diazepam + nordiazepam. I have never taken this. I found out diazepam is valium + I still don't know what nordiazepam is! I take a lot of meds and otc stuff. Could any of these cause false positives: Gabapentin,synthroid,ranitidine,seroquel,lamotrigine, daily multivitamin,vitaminD,crestor,calcium,81 mg. aspirin, ambien,cranberry caps,800 mg. motrin

I got a false positive cause of amoxicillin . the only thing I took , these hair tests are that inaccurate its untrue , 72 to 84 % accurate , 5 to 10 % of them are false results on just doing the test itself , the drug testing companies cover up , denying it as they would lose their billions of pounds of revenue a year , its a joke , testing is only in its infancy , so has so much more to do before it should be used as creditable , because its not at all , crap is not the word , the tests are so crude that it doesn't know the difference between eating poppy seeds and heroin, as they haven't got a good enough test to know the difference , look online u can find the list of the over 250 over the counter medicines that test u positive on a test but then again the companies will deny this big style , peoples lives are being ruined because of money ,profit of these companies ,

There is no help. DSS doesn't want to hear that there is such a thing as FALSE POSITIVE. We DO NOT DO DRUGS but our 2 children have been gone now for 4 months and father & I are going to substance abuse classes, taking surprise hair, urine & breathalyzers tests , mental health evaluation & whatever others hoops DSS wants us to jump through. I still try figuring out how this could have happened...but IT REALLY DOESN'T MATTER BECAUSE DSS PLAYS GOD WITH YOUR LIFE & YOUR CHILDREN! Youre just screwed!! Scary but true. What happened with Kelly & one year old positive baby but all others negative.

The antibiotic Ampicillin has been known to cause false positives for Cocaine on drug tests and depending on the length of your hair and how much of it they test, it can show up anywhere from 90 days to the rest of your life.

When the testing was done, where they aware of your medical problems and any medications you were taking?

sherryb, I am not finding anything on your list that would cause a false positive for Cocaine.

Have you taken anything else? Even over the counter products or herbal supplements?

I took a hair follicle drugs test and it came positive for cocaine and I never used drug in my life, the only thing I taken was hydrocodone 500mg from dentist. Why they don't ask your medical history before you are tested.

Could I possibly suggest that you get your doctor to write a certificate to take with you to court showing that the medication you have been legally prescribed does contain cocaine and this would show up on any drug test you have been asked to undergo. This will have the case thrown out of court - no worries!

Kelly, what are you doing about these results? Did DSS take your kids? I'm going thru same thing. My 19 month old baby tested positive for cocaine...high daily using dosage!! IMPOSSIBLE but that's what DSS said. Came w 2 police officers & took my baby girl & 10 yr old son w/o even showing me proof of failed test!! I'm scared to death. WE DON'T USE DRUGS!! This is a bad Lifetime movie I'm stuck in.
