Hi Doctor, I am a 57 yr old woman and am IgAD and was diagnosed 20 years ago. IgA is not my only disorder, it seems not to be a priority when I go in to the Doctors, but I am always reminded that I am sick and need to be careful. I had some lab work done thr other day and would like to ask a question, The IgA is 5, IgE is 3.2 and IgG is 1112. What is to low for the IgE, and what does it mean being so low. I m full of allergies and have been since I was a kid. Thanks so much
