A member asked:

What is the best way to diagnose autoimmune disorders in immune deficient patient on igg replacement? rheumy suspicious of lupus, but not definitive

A doctor has provided 1 answer

Related to the low gammaglobulin: Sometimes people with agammaglobulinemia can have musculoskeletal problems the diagnosis of lupus in this situation is unlikely sometimes one can have similar symptoms when infection is present. I would be very cautious in trying to say that lupus is present.
