Repeat IVIG question

Hi Tim / DeeDee,

I saw in your posts mention of a repeat of the IViG treatment.

I don’t have GBS but my brother does. When he was first diagnosed, they did five days — five hr each day — of this IVIG treatment.

Is what you’re describing the same type of treatment? And how do they determine if this is what’s needed — is it because of a setback? — or are they measuring the antibodies and there was an increase in the number of antibodies?

Many thanks…
Jann
