A person with ‘AB' blood group is sometimes called a universal recipient because of the
A
lack of antigen in his blood
B
lack of antibodies in his blood
C
lack of both antigens and antibodies in his blood
D
presence of antibodies in his blood
Correct Answer: Option B
Explanation
1. The question asks why a person with 'AB' blood group is sometimes called a universal recipient.
2. The ABO blood group system is based on the presence or absence of specific antigens (A and B) on the surface of red blood cells and corresponding antibodies (anti-A and anti-B) in the blood plasma.
3. Individuals with 'AB' blood group have both A antigens and B antigens on their red blood cells.
4. Because they possess both types of antigens naturally, their immune system does not produce antibodies against either A or B antigens. Therefore, their plasma lacks both anti-A and anti-B antibodies.
5. The lack of these antibodies means that if they receive blood from A, B, AB, or O donors, their plasma will not contain antibodies that would attack the donated red blood cells. This makes them universal recipients for red blood cell transfusions.
