Be glad that you live in America, where test results actually DO come in a short period of time.
Last year, when we were in Russia and my DS was in the hospital, I asked the drs to culture his staph infection so they'd be positive about the drug they were giving him (and so we could leave the hospital and give him an oral antibiotic.) My brother is a pharmacist and told me that the results would be back in 2 days. The drs laughed at me and told me that my DS would be cured before they'd get the results back there. They wouldn't have anything back for at least 12 days. They went on to say how hard it is if someone thinks they have cancer and they don't get the results back for a month.
I hope it makes you feel a little better. The waiting stinks, but it could be worse. I hope you get the results that you want!
