Question

15. A patient's immune system will attack cells in transfused blood if the donor's blood type is not compatible with the patient's blood type. Match each donor with all patients that can safely receive the donor's blood based on the ABO blood type system. Donors may be matched with more than one patient.

Patient has type A blood. __________________________

Patient has type B blood. __________________________

Patient has type AB blood. __________________________

Patient has type O blood. __________________________

a) Donor has type AB blood.

b) Donor has type A blood.

c) Donor has type B blood.

d) Donor has type O blood.

Answer 1

Patient A = Donor A, donor O

Patient B = Donor B, donor O

Patient AB = donor A, donor B, donor O, donor AB

Patient O = donor A

Person with A blood type have antibody B. So, can take blood from A and O.

Person with B blood type have antibody A. So, can take blood from B and O.

Person with AB blood type have antibody A and antibody B. So, can take blood from A, B, AB, O.

Person with O blood type have no antibodies. So, he can donate to anyone but will can take only from O.

Universal donor = O

Universal recipient = AB
