My results:
Initial test-44ng ml
Confermation test-44ng ml
Something is very fishy here. An Immunoassay is used when conducting the initial screening. All Immunoassays are a Pass/Fail endeavor and have no ability to yield quantitative values. So with that being pointed out, how can they come up with 44 ng (or any quantitative value for that matter) on the initial?

In order to obtain quantitative values, the sample must be run through the GC/MS (which is used for the confirmation test).
