Which blood type has no plasma antibodies?


  1. Type A
    • Rationale:

      Individuals with type A blood have anti-B antibodies.

  2. Type B
    • Rationale:

      Individuals with type B blood have anti-A antibodies.

  3. Type O
    • Rationale:

      Individuals with type O blood have both anti-A and anti-B antibodies.

  4. Type AB
    • Rationale:

      Individuals with type AB blood have neither anti-A nor anti-B antibodies.


An antibody is defined as protein made by plasma cells.


Learning Outcomes

There are several types of antibodies that help determine blood type. These antibodies include anti-A, anti-B, and a combination of the two. Individuals with type AB blood have no antibodies.

Test Taking Tip
