1. You’re right, info is conflicting. By some standards a 121 is a low positive. Peth is absolutely worthless in the context of your overall drinking habits by itself. Period. You WONT find a learned opinion that it is.

2. Trusty old Lab Corps recently produced a positive test like yours and it wasn’t the guy’s blood as shown with DNA testing... so there’s that.

3. Greg Skipper talks a lot about individual PLD variance that affects these results. Ted Shultz talks a lot about individual hematocrit variance that also affects results. I’m certain your PLD levels and hematocrit weren’t recorded at the time of your test...

4. I’ll private message you so you can get in touch with me if you wish. I can provide you with expert opinions concerning PETH testing that might sway the GAL to the inefficacy of this sham test.
