Which one among the fallowing Statements about blood trans- fusion is correct ? Blood group B can give blood to—

Result
Your answer: —  ·  Correct: B
Explanation

Blood group compatibility is determined by the presence of antigens on red blood cells and antibodies in the plasma. Individuals with blood group B have B antigens on their red cells and anti-A antibodies in their plasma. Consequently, group B individuals can safely donate blood to recipients of the same group (B) and to those with group AB, as group AB is the universal recipient and lacks antibodies against A or B antigens. Regarding reception, group B individuals can receive blood from other group B donors or from group O donors, who are universal donors [1]. They cannot receive from group A or AB because their anti-A antibodies would cause an immune reaction against the A antigens. Therefore, group B can give to B and AB, and receive from B (and O), making option 2 the most accurate description of the provided choices.
