Confirmation of passing (how accurate are at homes?)

[we20vmk4]

What's your metabolism? If its fast, then you probably have a good chance of passing with 19 days abstinence and the little bit of dilution. The line doesn't have to be as dark as the control line, as long as its a line. They say if you can photocopy it, its a pass.

So are at home drug tests as accurate as the lab tests? I had taken the at home test one hour after the lab test. Could I possibly pass the at home one and fail the lab test when the time between both tests were so close together?
