I am a nurse and am frustrated with healthcare. How far do I need to go to get a dx Hypogammaglobunemia?

We suspect this may be Lupus. If you are neg for gamma and hemo tests this leads away from Hypogammaglobunemia.You definitely have the family history. The reason we suspect Lupus is because it mimics so many other diseases/symptoms and because hypogammaglobunemia is so rare. You might try a hematologist for a DX.
