All About Antibodies

An educational resource for families dealing with alloimmunization, also called isoimmunization, Rh disease, erythroblastosis fetalis, and hemolytic disease of the fetus and newborn (HDFN). We’re sorry you were diagnosed with antibodies during your pregnancy, but we are glad you’re here and we will be happy to help you however we can.

New to the disease? Start here

Finding out you have antibodies is a scary thing, but it doesn’t have to be! Armed with the right knowledge, you can be informed about your baby’s condition, and be a partner in your baby’s health. You are your baby’s biggest advocate. Unfortunately women around the world receive substandard care and their children suffer as a result. You have to educate yourself about your antibodies, what your country’s standards are, what tests should be done, and what treatment options are out there. At the end of the day you are the one who lives with the daily reminders of how your pregnancy and newborn time went.

Read everything you can about your disease. With proper treatment, you have every reason to expect a live baby, but you must make sure that you are getting the proper treatment. There are new and proven treatment methods for helping babies with HDFN as early as 8-12 weeks gestation. Your baby is not automatically going to be anemic, brain damaged, or anything else. You can have a perfectly healthy baby who will turn into a normal adult, and you can have more children.

This page exists to help women advocate for their babies. We do this by providing educational information to moms so they can better understand their disease; by increasing understanding of alloimmunization; and by raising public awareness about alloimmunization. All About Antibodies empowers women to be partners in their prenatal care. We are sharing information today to save the lives of tomorrow.
