OK so I called the at home test Co. today and they used a gc/ms test on my sample which came up at 55 ng/ml. This sample was from 6/4/09. I tested myself with my morning void on 6/9 and it came up negative with a very faint line. I practiced a mild dilution (48 ounces of water over 2 hours) that afternoon and it came up negative with a stronger t line. I tested myself this morning with my first void and it came up negative with a very faint t line. I am going to take my UA on 6/15 at Quest Diagnostics, it is a 6633n sap 10-50 gc/ms. Any opinions on my chances? I am thinking of using a mild dilution for the test, 32 ounces of water and 40 ounces of gatorade. Any help would be great.
