If you're RhD negative, your blood will be checked for the antibodies (known as anti-D antibodies) that destroy RhD positive red blood cells. If anti-D antibodies are detected in your blood during pregnancy, there's a risk that your unborn baby may get affected by rhesus disease.

Anti Rh D Immunoglobulin is needed to prevent a disease called Rhesus disease. This can help to avoid a process known as sensitisation in women. This is a condition when a woman with RhD negative blood is exposed to RhD positive blood and develops an immune response to it.

Anti Rh D Immunoglobulin should be administered under the supervision of a trained healthcare professional or a doctor only and should not be self-administered. Anti Rh D Immunoglobulin is given into a muscle, normally in the upper arm. Follow your doctor’s instructions carefully to get maximum benefit from Anti Rh D Immunoglobulin.

Anti Rh D Immunoglobulin will be given as an injection at 28 weeks of pregnancy and within 72 hours of birth, if your baby is Rh D positive. Consult your doctor before getting Anti Rh D Immunoglobulin.
