Antigens and Antibodies
of Blood TypeThe purpose of this activity is to provide
practice with determining antigens and
antibodies
Watch the following video to learn the basics:
Return to the start.
Test your knowledge after you watch the video.
Let’s test your understanding of the basics.
• Read each question and click on the correct
answer.
• Continue to practice until you can answer the
questions with ease.
• Watch the video again if you need more
information.
Return to the start.

First let’s review the antigens
• Antigens are like
identifiers on the
surface of the red
blood cells.
Return to the start.
What kind of antigen does A-type blood possess?
• Only A-type
• Only B-type
• A and B-type
• none
Return to the start.
What kind of antigen does B-type blood possess?
• Only A-type
• Only B-type
• A and B-type
• none
Return to the start.
What kind of antigen does AB-type blood possess?
• Only A-type
• Only B-type
• A and B-type
• none
Return to the start.
What kind of antigens does O-type blood possess?
• Only A-type
• Only B-type
• A and B-type
• none
Return to the start.
Now let’s think about the antibodies
• Antibodies help to
protect the blood.
• They float around in the
plasma surrounding the
red blood cells.
• They are experts at
finding incompatible
cells and destroying
them.
Return to the start.
Next question
What types of antibodies does A-type blood possess?
• Only A-type antibodies
• Only B-type antibodies
• A and B-type antibodies
• No A or B type antibodies
Return to the start.
CORRECT!• A-type blood has B-type
antibodies
• If a person with A type
blood was transfused
with some B-type blood,
the B-type antibodies
would attack those B-
type blood cells
Return to the start.
Next question
What types of antibodies does B-type blood possess?
• Only A-type antibodies
• Only B-type antibodies
• A and B-type antibodies
• No A or B type antibodies
Return to the start.
CORRECT!• B-type blood has A-
type antibodies
• If a person with B type
blood was transfused
with some A-type
blood, the A-type
antibodies would
attack those A-type
blood cells
Return to the start.
Next question
What types of antibodies does AB-type blood possess?
• Only A-type antibodies
• Only B-type antibodies
• A and B-type antibodies
• No A or B type antibodies
Return to the start.
CORRECT!• AB-type blood has no A or B
type antibodies
• If a person with AB type
blood was transfused with
some A or B-type blood,
there wouldn’t be any
reaction! They are a
universal recipient for many
types of blood.
Return to the start.
Next question
What types of antibodies does O-type blood possess?
• Only A-type antibodies
• Only B-type antibodies
• A and B-type antibodies
• No A or B type antibodies
Return to the start.
CORRECT!• O-type blood has BOTH A and
B-type antibodies
• If a person with O type blood
was transfused with some A or
B-type blood, their A and B-
type antibodies would attack
those foreign blood cells
Return to the start.
Next question
Let’s pretend we have a lot of B-type
blood on hand. Who could receive a
transfusion of this type of blood?
• A person with B-type blood
• A person with AB-type blood
• A person with A-type blood
• A person with O-type blood
Return to the start.
Do you need a review?
You’re the right type!• Having completed this activity, you should now
have an understanding of how antigens and
antibodies relate to blood type.
Return to the start.
That’s right!• This blood type does not have Anti-B antibodies, so
there would be no transfusion reaction.
