Me and a freind both tried it around the same time a few months ago after being recommended it by a colleague. It was correct for us, and it was a fairly simple and easy test, so I was happy. My girlfriend works in a hospital lab and did some research before we went ahead and bought it (it's $399 after all!) and she was happy that the prinicple behind the test was OK. They quote a 90%+ accuracy I think.
May as well go ahead if you really can't wait! ;)
