The beautiful thing about my situation is that I get to schedule and pay for the screen myself
It is too late for me to purchase any adulteration test strips.
Since youre able to schedule the U/A yourself, why is it too late for you to order any adulteration test kits?
If its a money issue, you can always borrow the money to place your order (the kits are not at all expensive), and many online vendors offer overnite shipping (although its an extra-cost option, but nevertheless still inexpensive).
