Hello @fairlaneowner -- welcome to Mayo Connect. We are glad you found us. I'm sorry to hear about the risk of losing custody of your children due to PEth tests false positives. The best thing you can do is learn as much as you can about the testing and be a strong advocate for yourself. Here are a few more links I've found that point out the problems with the current PEth testing:

Google Scholar (https://scholar.google.com/) is a good tool to search for information and the results can be sorted to get the newest/latest information.

This PETH test is BS. Point. Blank. I know several non-drinkers who’ve tested positive and suffered the consequences.

I think it’s time to get Congress involved! In the meantime, might we not fight fire with fire? This PETH is created by an enzyme called Phospholipase D. Amazon (and many local health stores) carry things that block Phisoholipase D. Phytoceramide and Honokiol are two of them.

My $.02.

Hello @roxycarmichael -- welcome to Mayo Connect. Your 2¢ is worth a lot when helping another Connect member. Thank you for sharing! It sounds like you may have personal experience with PEth testing. If you are able to share, it may be helpful to other Connect members.

On dealing with the court system, I’ve found no traction in pointing out the potential faultiness of my PEth tests, because my judge trusts the test & his lab. Long story short, I’ve gotten nowhere with the biology argument. I’m having to go around the (wrongly) positive results. I have three negatives and two positives, all with no drinking at all. The judge is allowing For a toxicologist testifying on my behalf to explain away two recent (false) positive PEth tests over against the negative results of a hair alcohol test, negative results of a fingernail alcohol test and a polygraph (not yet taken). I’ll post the ultimate results.

Thank you for sharing @fairlaneowner. Hard to believe the legal system is so messed up and allows testing with using something that is not FDA approved. Good luck on toxicologist testifying on your behalf. Hopefully the judge has a heart and listens.

Hi, @fairlaneowner -- just wanted to see how things are going with your process with the courts and the potential faultiness of your PEth tests?

The morning after that evening’s surprise test, I took my own back-up test at another testing facility nearby. The sample went to the same lab (USDTL) at the surprise test for analysis. Results: negative! How can that be? How can I test positive from one tester and negative at another, within hours? The PEth test is a 2-3 week look-back. So far, Forensic DNA & Testing has shown me positive three times, where every other tester results came back negative. All of it with no alcohol consumption at all. Something isn’t right. I also recently did a fingernail EtG which came back negative, which I was told looks back 6 months. Currently I cannot see my kids because of Forensic DNA & Testing PEth Test positive results. I’m working hard to vindicate myself, included getting a toxicologist to review all the results & speak on my behalf as not drinking.

Hi @roxycarmichael can you explain alittle more about Phytoceramide and Honokiol? Do they help show a negative result on the PeTh blood sample?

I sent you a PM but we need to talk... Same Lab; Same test facility; same issue...

Anyone else seeing this with either USDTL and/or Forensic DNA? What other testers did you use?

I should add we also have (multiple) conflicting test results to counter failed tests at USDTL using direct blood draw vs their bloodspot cards.
