If you are RhD-negative, this test can determine whether your baby is RhD-positive — the situation where anti-D antibodies can form. If your baby is RhD positive, your clinician will give you anti-D immunoglobulin to stop these antibodies from forming.
If your baby is RhD negative, you do not need to be given these injections, allowing your clinician to give anti-D immunoglobulin to those who need it and helping youavoid unnecessary treatment.
