Well that makes some sense. I guess I always hesitate to "bother" them. I'm going to call and ask why we are doing it and if it is really necessary at this point or if we can take a wait and see approach. I've done lots of different tests in my life and it's not that I here it is painful that I'm hesitating, it is more that if it really isn't going to show us anything, why do it? Thanks. I'll give the office a call.
