Question:

If both parents have died is there still anyway i can find out their blood groups?

Best Answer - Chosen by Asker: Blood groups are NOT on birth certificates. I don't think they are even on death certificates. In order to get the blood type your parents are you would have to gain access to some kind of lab work they have had done in the past. I looked at my birth certificate and it does not state any blood type on it. I would research a doctor they may have been under the care of and with proof of a death certificate you may be able to get their blood types.
