Have you been exercising throughout this period?

Are these all first morning voids or samples throughout the day?

The only logical explanation I can come up with is exercising habits and hydration levels. It's very possible to be down to 25-50 ng/ml one day, then go out and exercise and all of the sudden you can spike up dramatically to failure levels. Exercising is great, but burning it out of your fat, means it has to go somewhere, and that somewhere is right into your test cup.

But even so, going from 68 all the way to 351 is very extreme. Given how long you've been clean, I'm actually very shocked to hear a 351. That's very high.

Wish I had more information for you, I'm pretty stumped by this one though.
halo09 Reviewed by halo09 on . Drug tests varying like crazy, wtf? I am a 48 yo male, 180 pounds and I have been a regular smoker for about 15 years. I stopped smoking on December 14, 35 days ago. I've been taking store bought drug tests and getting tested by a lab randomly and the results I'm getting are very different. I got tested by the lab on Jan 3 and got a 275, I did a store bought test 2 days later and I didn't pass but I sent it into the lab and it came back a 68. I took three more store bought tests on Jan 8, Jan 11 and Jan 21. I failed the first one Rating: 5
