I am using First Check as a pre-screen test. The real test is a 5-panel LabCorp, I know that they do a specimen validity check for creatinine, specific gravity, pH and nitrites, so if I can avoid diluting I would prefer to, so....

At one week dry, there was no line to be seen at the THC mark.

At two weeks, there is a line, it is fainter that the control line, but it appears solid. I know others have said a line is a line, however, too great of an opportunity to screw it up.

Pre-employment screen 5 days - any opinions on if the line will be darker?
