I recently heard about an ELISA blood test. I don't know what the letters stand for, but it is a blood test to find out what foods you are allergic to. I read about it in a newspaper. A lady had written in and said she had this blood test done and found out that she had an internal yeast allergy, and that her body was reacting to many of the foods that she was eating. She changed her diet and lost over 45 pounds. I want to ask my doctor about it, but I want to find out a little about it before I ask. I am hoping that it might be able to show up something that might make me feel better. If anyone knows something about this blood test, please let me know! Thanks!
