Suppose your blood is AB positive. This means that:
a. Agglutinogens A and B are present on your red blood cells
b. There are no anti-A or anti-B antibodies in your plasma
c. Your blood is Rh⁺
d. All of the above

Verified step by step guidance

Step 1: Understand the ABO blood group system. Blood type AB means that both A and B agglutinogens (antigens) are present on the surface of your red blood cells.

Step 2: Recognize that individuals with blood type AB do not have anti-A or anti-B antibodies in their plasma, because having these antibodies would cause agglutination against their own red blood cells.

Step 3: Understand the Rh factor. If the blood type is AB positive (AB⁺), it means the Rh antigen (also called the D antigen) is present on the red blood cells, making the blood Rh positive.

Step 4: Combine these facts: AB blood type means both A and B antigens are present, no anti-A or anti-B antibodies are in plasma, and the positive sign indicates the presence of the Rh antigen.

Step 5: Conclude that all the statements (a, b, and c) are true for AB positive blood, so the correct answer is 'd. All of the above.'

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

AB Blood Group Antigens

The AB blood group means that both A and B agglutinogens (antigens) are present on the surface of red blood cells. This is a result of inheriting A and B alleles, causing the immune system to recognize both antigens as self.

Plasma Antibodies in Blood Types

Individuals with AB blood type do not have anti-A or anti-B antibodies in their plasma because their immune system recognizes both A and B antigens as normal, preventing an immune reaction against these antigens.

Rh Factor and Blood Typing

The Rh factor is a protein found on red blood cells; if present, the blood type is Rh positive (Rh⁺). Being AB positive means the person has both A and B antigens and the Rh antigen, which is important for blood transfusions and pregnancy compatibility.
