Blood type matching

The first test for compatibility is the ABO or blood type. This can be done through your family doctor, Canadian Blood Services card or through the donor coordinator.

Blood type compatibility guide

 A donor with this blood type

 Can donate to a recipient with this blood type


A, B, AB or O


 A or AB (sometimes O)


 B or AB



An O blood type donor can donate to any blood type recipient. A recipient with AB blood type can match any donor’s blood type. In living kidney donation your positive or negative (Rh factor) is not important.

You will need to fax a copy of your blood type or Canadian Blood Services card to the donor coordinator at 613-738-8489. If you are not compatible with your recipient, you may want to look into the Living Donor Paired Exchange Registry.
