Answer: AB blood group is the universal acceptor.
Though the blood of human beings appears to be similar it differs in certain aspects. Two popular blood groupings that are used worldwide are ABO and Rh.
ABO Blood Grouping
ABO blood grouping is based on the absence or presence of two surface antigens namely A and B on the RBC. The antigens and antibodies are distributed in four blood groups A, B, AB, and O. Check the blood group and the donor’s compatibility in the table given below.

Antibodies on Plasma
Antigens on RBCs
AB, A, B, O
Rh Blood Grouping
Another antigen is also observed on the surface of RBCs of the majority of people which is Rh antigen. It is similar to the one present in Rhesus monkeys. The individuals in whom this Rh antigen is present are called Rh positive (Rh+ve) whereas those in whom it is absent are called Rh negative (Rh-ve).
Which Blood Group is Universal Acceptor?
A person with AB blood group is called a universal recipient or acceptor whereas a person with O blood group is known as a universal donor.
