Lacey O,
you should call whoever did the testing and ask to see the results. Just because they didn't call, doesn't mean that there's nothing wrong. Two different family members of mine have had thier lives in jeopardy because the lab never called back. It was always some simple clerical error, humans make mistakes, but now I always demand to be shown the results. If the lab won't respond to you, have you doctor do it.
I don't want to start a panic, and I don't hold anything against med labs, but I say that it's my life and I want to know what's going on.
