burnt - i will for sure buy a home test before to know if i need to practice heavy dillution, the drug test isn't until may 18 and i quit on april 6 so i am going to wait longer before i start testing myself!
jane, i feel your pain, but i have always heard a faint line is still negative! what are you taking the test for with a 20 ng cutoff? i just kind of figured for pre-employment immunoassy it would be 50ng for me
