In the same position as you two possibly. Been getting PEth(finger prick) tests for over 4 years and just had my first positive ever. I tested at 24ng/mL according to the paperwork from USDTL. I was in complete shock! Within the same day of being notified I went and got tested again: PEth(finger prick) test, Urine ETG and Hair ETG. All three test came back negative. I'm very mindful and experienced, as a donor, in how the test collection is administered, 4+ years of doing this test!

The only thing that has changed for this test was got tested within 2 hours of finishing a trip. I have never gotten tested, by PEth, same day as working. I have seen all the same articles questioning validity of the PEth test vs contamintaion from Ethly Glychol products ie; Hand Sanitizers, disinfectant wipes, etc. I'm being told its impossible to test at a level of 24ng/mL without ingesting it. Times have changed in the past few months with COVID-19. I'm instructed by my employer to use these products (Flight Deck Wipes & Sani-Comm) to clean are workstations. Furthermore when positioning around the system your given Purell Wipes and one time use Purell gel packs. Every public place I go into has Hand Sanitizer. Again instructed to use these from my Employer who gets the imformation and recommendations from the FAA, who cites the CDC in the latest SAFO 20003 publication.

I've been very mindful of what I expose myself to, but at the same time its my responsibility to comply with procedures and guidelines from my employer to protect myself, crew and customers. I know this is going to be an uphill battle. Let me know if either of you need more information.
