Celeste, These articles might explain it better. Someone can have a deficiency of IgA but also have anti-IgA antibodies, meaning that the body would mount an attack against incoming IgA. Make sense?

They can filter out IgA in IVIG but it's such a "rare" situation that unless you ask, Magister, they might not do it. The reaction could be an anaphylactic reaction or nothing or somewhere in between.

Magister, I hope your docs know what they're doing! They had better try IVIG in a hospital setting. This is nothing to mess with.
