WIll I pass my drug test tomorrow?

Ok, so I have to pass a drug test tomorrow, and I have to have a nanogram lvl of below 20 . I tested myself on a take home test last thursday and passed, but the requirement was nanogram lvl of 50 or lower. soo I am really, really close obviously, and I have been running a lot and drinking a lot of water . What do you guys think ? Do I have a chance ?
