Pretty much what cdk said.
Also watch your fluid intake on the day of test. Take in just enough allow you to urinate for the test. Going overboard with fluids in a paranoid state of mind will only foil an otherwise negative "home free" result.

Labcorp will start off with a 50ng Immunoassay and if the sample tests negative on that, youre home free.
