Thanks for the response!

I took my home test this morning and it did say all was clear. I feel a lot better now that I know, but I still sent the sample to the lab for the gc/ms. Since I'm not sure if a lab is being used for the test or not, (it's a private hospital, so it's possible they can run the test themselves).

With luck, I'll have the result before test day.

This site rocks!
