Hi all! My husband is a pharmacist, got a DUI in 2014, went to rehab, lost his pharmacy license for a year, and has been doing monthly random drug testing since. His drug testing program swapped to USDTL roughly a year ago and they began PETH testing. He has always had NEGATIVE results until March 2020, with a positive PETH finger prick. He was required to use hand sanitizer prior to entering the facility due to covid. They did not have him wash his hands. The results came back as 127. The hand sanitizer used an ethanol based hand sanitizer, but the USDTL contact aka “the expert” says there is no way this affected his result. We paid the extra $250 for a retest which was also positive and only 54. They let him in the second chance program due to no prior positive tests and now has to randomly test 2x per month costing us $750 a month. Well, today he got a call stating his PETH finger prick was again positive at 52. They refuse to do a nail test saying that a negative nail test (even though it goes back 3 months) will not invalidate the PETH test, even though the previous test was PETH and hair etg, both negative. We now have to pay $800 for a lie detector test. This is absolutely insane. USDTL will not talk to customers, only collection sites. He was just off for the entire week prior to the test, so basically they are telling me that during our staycation with our 3 kids my husband was drinking everyday. Local contacts are not helpful. I am 100% sure my husband is not drinking. His program was ending in August, so I find it convenient that now he is having issues when he has done the 5 years of required testing after rehab and per the board of pharmacy. With a second positive test he is facing losing is pharmacy license and possible rehab again. It is like they want to stress him out so maybe he will drink. The PETH test cannot be accurate. I don’t believe all of these people can have this many false positives. He also knows a guy that has also had 2 false positives with PETH. They are trying to ruin people’s lives.
