I have been clean for 19 days now and I found out I have a urine test tomorrow for pre-employment screening.
I used the test strip and it shows two lines, but the second line is VERY faint. The test kit instructions say this doesn't matter but in my search for answers I see that other test kits have a note about faint lines meaning it very close to the thc limit. http://www.stardetox.com/product_thc...st-p13587.html
My questions is, how accurate are the thc test strips?
Has anyone passed a test strip but failed the lab test?
