Relax. It works.

I had a test at LabCorp last month and passed with QF. No problems.

Yes, a lab can tell if its synthetic... but your employer isn't paying for that test, unless you are an Olympic athlete or something.

As long as you can get it good temperature wise and have it signed off by a collector, you are good to go!
