Definition: A substance given when the body cannot produce enough antibodies on it's own.

Explanation: The immune system helps protect the body from germs. Fighting infections depends on the body's ability to make immunoglobulins (antibodies). When the immune system cannot produce enough antibodies, intravenous immunoglobulin (IVIG) may be needed to helps boost the immune system. It is given by IV (into the vein).

IVIG is made from blood plasma (the liquid part of the blood). It requires about 100 donors to make one dose, so donating for your child is not possible. When IVIG is made, many steps are taken to remove any harmful viruses such as HIV and hepatitis.

One does of ICIG protects your child for about 3 to 4 weeks. How often your child needs ICIG depends on his or her condition.
