Blood type compatibility

  • People whose blood type is A+ can donate to people whose blood type is A+ or AB+. They themselves can receive O+, O-, A+ or A- donations.
  • Donors whose blood type is A- can donate for people whose blood type is A+, A-, AB+ or AB-. A- individuals can receive donations of type A- or O-.
  • People whose blood type is B+ are suitable donors for recipients whose blood type is AB+ or B+. They themselves can receive donations of type B+, B-, 0+ or 0-.
  • Donors whose blood type is B- can donate to AB+, AB- B+ and B- recipients. They can receive B- or O- blood.
  • People whose blood type is AB+ can only donate to people with the same blood type, but they can receive donations of any blood type. 
  • The blood of AB- donors can be given to recipients whose blood type is AB+ or AB-. AB- individuals can receive blood from any RhD negative donor. 
  • People whose blood is type O+ can donate to any RhD positive recipient. They can only receive donations of type O+ or O-, though.
  • Donors whose blood type is O- are universal donors, because O- blood can be given to people of any blood type. However, they themselves can only receive donations that are also O-.
