Is a 2nd opinion necessary on diagnosis of Common Hypogammaglobulinemia?
I was recently diagnosed with Common Hypogammaglobulinemia by my allergist (immunoligist). He ran some blood tests to check my immunoglobin levels, as I am currently fighting my 3rd sinus infection THIS YEAR. When it came back low he sent it for further testing. 2 of the 4 subclasses were low. He told me that means that my body does not produce the antibodies to fight bacterial infections and that I had Common Hypogammaglobulinemia. He wants to start me on Gammagard infusions. My husband wants me to get a 2nd opinion. My question is, is that really necessary since his diagnosis was based on blood tests?
