Yet Another Way Drug Testing Fails: Baby Products Linked To False Positive Drug Test Results In Newborns

    Commercially available baby soaps and other wash products that are commonly used with newborns may yield false positive results for THC in immunoassay drug screens, according to a just published study in the journal Clinical Biochemistry.

    Investigators at the University of North Carolina, Department of Pathology and Laboratory Medicine, assessed the impact of various baby wash products on drug-free urine samples after a number of false positive cannabinoid screening results were suspected at their hospital.

    Researchers reported: “Mixtures of drug-free urine with various commercial products and materials that commonly contact newborns in our nursery were prepared and tested using the immunoassay screening methods in our laboratory. … Addition of Head-to-Toe Baby Wash to drug-free urine produced a dose dependent measureable response in the THC immunoassay. Addition of other commercially available baby soaps gave similar results, and subsequent testing identified specific chemical surfactants that reacted with the THC immunoassay.”

    They concluded: “We have identified commonly used soap and wash products used for newborn and infant care as potential causes of false positive THC screening results. Such results in this population can lead to involvement by social services or false child abuse allegations. Given these consequences, it is important for laboratories and providers to be aware of this potential source for false positive screening results and to consider confirmation before initiating interventions.”

      Sounds to me like they’re trying to take our babies from us.

      this is really nice to know…if only this info was known a few years ago when my sister was accused and had to fight it.

      This is nice to know but there is not enough information for the public to be fully informed, such as a list of all the products that are being tested and showing up as false positives. Many people have sensitive skin and use baby products on themselves due to them being “safer” on their skin so it is important for us to know exactly which products cause this for such times as pre-employment drug screening.

    4. Ms. Minnesota says:

      The information needs to be put out there!!

    5. Joe says:

      This is a joke. Get science to do chromatography and spectrometry of the samples, then they might get the tests right. As far as concentration is concerned, I’m sure they can figure that out.

      NORML: Interesting article….I am a transit driver and worry about randum drug checks.I dont smoke much and nothing else.I dont use it on work hrs. and think it wrong if you want a little pot after work or on the weekends but have to worry come Mon.I am thin and they say skinny people dont have the fat cells that hold THC.Ive been tested 5-6 times now with nothing found.So far, so good I guess. Thanks LEGALIZE IT!!!!!

      drug testing is only testing for cannabis anyway. nothing else stays in your system long enough. so there is no actual drug testing in the united states, it’s ALL cannabis testing. if you smoke a joint, you will not find a job unless you have a family member or good friend who can get you in. trust me, i know, i have a college degree and am an honorably discharged veteran who has been turned down for 5 jobs because i use cannabis instead of taking prescription or even non-prescription drugs…

      it’s f’ng ridiculous… serve my country for what? so i can be poor and have to do illegal activities just to pay my bills so i don’t have to live on the street…

      yeah boy, your drug testing sure showed me, government…

      showed me that you’re a bunch of hypocritical NOBODIES who care only for themselves…

    9. Fireweed says:

      The irony is that the same people outraged at government having too much of a say in things are the very people working hand in hand with government to support widespread drug testing in the workplace. The reality is they want government to let big business do whatever they want but want government to give the green light to them having control over the lives of the average working stiff. It is definitely becoming a corporocracy.
