What is included in an ivig infusion?

IgG antibodies: Intravenous immunoglobulin (ivig) is a collection of IgG antibodies pooled from the plasma of over 1000 blood donors. Extensive processing to remove other antibodies and possible contaminants makes ivig expensive. The solution that the antibodies are dissolved in sometimes is high in sugar & should be given carefully to diabetics. Most brands also have preservatives in the product.

IgA too: Iga is usually found in most ivig preparations, therefore subjects with selective IgA deficiency are contraindicated to receive this form of ivig due to the risk of anaphylaxis.
