Pregnant women are always given a blood group test. This is because if the mother is RhD negative but the child has inherited RhD-positive blood from the father, it could cause complications if left untreated.

RhD-negative women of child-bearing age should always only receive RhD-negative blood.

You can donate blood if you:

  • have a good overall level of health
  • are 17 to 66 years of age (if it's your first time)
  • weigh at least 50kg (7st 12lb)
