Blood group type test and Anti-D injection Bookmark this page

Your midwife or doctor will want to do a blood test in early pregnancy to find out your blood group. They want to know because if you have a ‘negative’ blood type (A-, B-, O- or AB-) and your baby turns out to have a positive type, this can cause serious health problems for baby and problems in future pregnancies.

But you can’t tell what baby’s blood type is until after birth, so if you’re a ‘negative’ blood type, you’ll be offered a special injection called Anti-D at your 26-28 week and your 34-36 week visits. This reduces the risks to you and your baby. After your baby is born, you’ll have another injection if your baby has a positive blood type.

Ask your obstetrician, doctor or midwife for more information.

Asking for women carers

Some women want only women health professionals to care for them during pregnancy, labour and birth. You can ask for a woman midwife or doctor, but it might not be possible to have one – especially if you or your baby need urgent or specialised medical attention.
