I passed at Quest with quick fix. I think you're smart not using the hand warmer. I did and they had to call my employer to see if I should take another test. My sample read at 100 degrees. Keep it body temp and you WILL pass with flying colors.
the only thing that could screw you is if it's too hot.

I just wanted to make absolutely sure the Quick fix will work a lab test as it is more in depth than a dip stick. I know a lot of people say they don't want to spend the money, but this Rating: 5
