Textbook Question

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

Understand the concept of blood types: Blood types are determined by the presence or absence of specific antigens (agglutinogens) on the surface of red blood cells and the antibodies present in the plasma.

Review the characteristics of the AB blood group: Individuals with AB blood type have both A and B antigens (agglutinogens) on their red blood cells and do not produce anti-A or anti-B antibodies in their plasma.

Understand the Rh factor: The Rh factor is another antigen that can be present on red blood cells. If the Rh antigen is present, the blood type is Rh⁺ (positive); if absent, it is Rh⁻ (negative).

Analyze the options provided: Option (a) states that agglutinogens A and B are present on red blood cells, which is true for AB blood type. Option (b) states that there are no anti-A or anti-B antibodies in the plasma, which is also true for AB blood type. Option (c) states that the blood is Rh⁺, which is true for AB positive blood. Option (d) states 'all of the above,' which combines all the correct statements.

Conclude that the correct answer is the option that includes all the accurate statements about AB positive blood, which is option (d).

Key Concepts

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

Blood Type and Agglutinogens

Blood type is determined by the presence of specific agglutinogens (antigens) on the surface of red blood cells. In the case of AB positive blood, both A and B agglutinogens are present, which means the individual can receive blood from any ABO type without risk of agglutination.

Antibodies in Plasma

Individuals with AB blood type do not produce anti-A or anti-B antibodies in their plasma. This absence of antibodies allows them to accept blood from any ABO group, making AB blood type the universal recipient in transfusions.

Rh Factor

The Rh factor is another important blood group system, indicated by the presence of the Rh antigen (D antigen) on red blood cells. If an individual is Rh positive (Rh⁺), it means they have this antigen, allowing them to receive Rh⁺ or Rh⁻ blood without complications related to Rh incompatibility.
