@jfn Thank you. I am trying to keep a good attitude about it; just wish they could have scheduled it a bit sooner as the more time I have to think about it the more apprehensive I am. Maybe the holidays will give me something else to think of. I'm certainly glad to hear that they have made advancements in admisitrating these types of tests. I think also that the person who did my first (and only) test didn't have a clue what he was doing. Hopefully this technician will be much better. Again, thank you so much.
