As others have commented, your IgG and IgM are low. I'm not sure why the immunologist that ran the tests hasn't followed up with you about the next step...whether he thinks further testing for CVID is warranted (subclasses, and vaccine tests) or if he thinks you should see a rheumatologist at this point to get his/her input about autoimmune disease (at least 25% of those with AI disease are also immune deficient).

Someone needs to step up tot he plate for you and provide some direction. I wold contact the immunologist and get his opinion and if you have current autoimmune type symptoms, then see a rheumatologist (can't hurt).

Do you know the results of your skin biopsy?
