Anatomy and Physiology
1) In the clinical setting, how do we actually determine someone’s blood type?
When somebody needs a blood transfusion, the clinician needs to find out what their
blood type is to make sure they get the right type. How? You can figure this out. I’m
going to give you all of the information you need, and then you are going to predict how
blood types are assessed in the clinic.
First, you need to know that when antibodies attack RBC, the reaction creates clumping,
called agglutination. This is a visible reaction- you can see it happen!
Next, you need to know that to determine somebody’s blood type, the clinician has a vial
of antibodies that attack A (called anti-A), a vial with antibodies that attack B (anti-B),
and… I know you know where this is going… a vial with antibodies that attack Rh (guess
what that’s called!). And, of course, they have a sample of the person’s blood.
Okay! Come up with a hypothesis about how you could do this. Just try to figure
out how it could be done.
