The universal blood recipient group is:
**Core Concept**
The universal blood recipient group is determined by the absence of specific antibodies against ABO blood group antigens. This individual can receive blood from any ABO blood group donor without risk of an adverse reaction.
**Why the Correct Answer is Right**
Individuals with type AB blood have both A and B antigens on their red blood cells, but they lack the corresponding antibodies against these antigens. As a result, they can receive blood from any ABO blood group (A, B, AB, or O) without triggering an immune response. This is because the presence of A or B antigens on their own red blood cells prevents the formation of A or B antibodies against these antigens.
**Why Each Wrong Option is Incorrect**
**Option A:** Individuals with type A blood have A antigens on their red blood cells and anti-B antibodies in their plasma. They can only receive blood from A or O group donors.
**Option B:** Individuals with type B blood have B antigens on their red blood cells and anti-A antibodies in their plasma. They can only receive blood from B or O group donors.
**Option C:** Individuals with type O blood have no A or B antigens on their red blood cells, but they have both anti-A and anti-B antibodies in their plasma. They can only receive blood from O group donors.
**Clinical Pearl / High-Yield Fact**
To remember the universal blood recipient group, recall that AB blood type individuals can receive blood from any ABO blood group, but they can only donate to individuals with AB blood type.
**Correct Answer: C. Type O blood is the universal donor group, not the recipient group. Type AB blood is the universal recipient group.**
