Wow, seems like you can't catch a break! The tests the immunologist ordered are to test for different types of immune deficiencies, to see if her white blood cells work properly, which might be a reason why she gets so many infections, the CBC looks for anemia, platelet count and size, as well as a breakdown of the diffreent types of white blood cells. The H. Flu test is done to see if her body responded adequately by creating antibodies to the 4 shots she must have received over the first 2 years of her life, again to test how her immune system is working. The sweat test is done to look for cystic fibrosis, though there are several blood tests that can be done nowadays to look at the most common types of mutations that cause cystic fibrosis and are easier than the sweat test. I know it's a lot to take in, but if things don't seem to be working out, (not sure what type of insurance you have, if it's a PPO, I would really just look for another immunologist, like you did with the ENT, and who is hopefully closer to you than 2 hours away!! and schedule and appointment and sign a waiver to have the old immunologist fax over her records; if it's an HMO, then I would go back to her pediatrician and ask for a referral to another one, but sometimes those take a few weeks, which obviously sucks). When you go back to the immunologist, ask him/her to explain in detail what they think they are dealing with, and what each test is for. Make a list of all the questions you have and go down the list with each specialist. Good luck!
