Thanks Burnt Toast - I appreciate the support.

If I can play devil's advocate, because I know nothing about the lab or employees - let me throw this out there:

If a lab tech looks at their test, is it possible they don't look at the test closely enough to discern line? Or would it be possible that it is faint enough to be mistaken for not being a line, and having it sent for further testing? I believe the test is for the 50 n/g usual cut off.

I guess my question is if it gets set to the gc/ms - are the standards lower? I read on some forums that the gc/ms tests are automatically tested at 20 n/g, not sure if that is true or not.

My concerns are all but alleviated, thanks.
