What Can Cause A False Positive For Morphine In Hair Folicle Test (Top voted first)

Updated

My 13 year old son tested positive for morphine in a hair folicle test. He says he has not taken morphine and I believe him. Is there anything that could explain this? I am losing custody of him because of this. If anyone has any explanation for this please help.

That is absolutely NOT true! There can be false positives as well as false negatives in hair testing. I know the man who invented the procedure! If the hair is only being run on an EIA, or card test....it is very possible to have a false test. It must be confirmed on GC/MS or LC.MS/MS.
Codeine breaks down into Morphine....just an FYI. I am a real CLS and Doctor.

Opiates especially morphine will not show false positive unless another opiate was taken. Hydrocodone, oxycodone. You son may have been given one by a friend telling him it was headache medicine. I am very sorry to hear this situation but when I was his age every once in a while a friend would take stuff from their parents medicine cabinet....etc. Please have an honest talk with your son and make it clear that you are not upset just want to know the truth whether he was offered then go from there I hope everything works out.

Yes hair tests are very specific and are used to clear ppl who say they have never touched anything because in hair they can check back 90 days and if it says it's there it was... maybe a friend gave it to him without his knowing but there's no false positive in hair. I use hair test to clear my name when false positive comes in urine... sorry not answer you wanted. but it's truth...

U r too cool to take time out for her doc.& I pray u r right. The headache thing is plausible too. It's drastic but u can get a private lie detector for about $ 200 But LOOSE custody!!! What DS POS for the whole 90 days??? They can tell u how long ago he supposedly took it. 1x or often. Your lawyer better know all this and more!

I am prescribed ms cotton30mg and 15 mg hydrocodone 10325, neurotion, ability, and clonazepam and was recently switched from brintellix to viibryd. My urine drug screen came back positive for benzodiazepines, with it saying temazepam nordiazepam and oxazepam all were positive and also was positive for codeine. I didn't take any benzo other than my clonazepam and it can back not being detected in my system when I took it all month long didn't take any other benzo and I never touched any codeine. I feel like I got screwed real hard how could there be so many mistakes on 1 urine test so now my Dr wants to take me off all of it except the ability and the ssriand I have sever anxiety issues and depression and horrible back problems besides the fact I am fighting my dissability case right now. I have one more month of meds before he will no longer be my physicians my question is what could of caused all the false positives and the false negative and Will another Dr be willing to prescribe me my meds when I did nothing at all wrong this time. I did test positive a year ago for oxycodone but only because my Dr didn't write my script for my fytenal on a Friday so rather than withdraw all weekend I had an old prescription of oxycodone I took over the weekend til I could get my regular med on Monday and yes my fytenal was due on friday
