How Blood Type is Determined
Jump to the quiz at the end of the tutorial.
Introduction to The Blood Type Test:
The blood type test determines which antigenic molecules are present on the surface of RBCs.
- A glass slide is
divided into sections and labeled.
- A finger is
lanced and a small drop of blood is allowed to accumulate.

- A large drop of blood is
placed in each of the three sections.
- A drop of anti-serum is
added to each drop of blood.
- The anti-sera typically contain plant proteins that react similar to the body’s own IgM and IgG antibodies.
- The anti-sera is
mixed with the blood.
- The clumping (=
agglutination) of RBC’s indicates that A. B. or Rh antigens are present on the RBCs
- Group A and B reactions are most rapid and noticeable. Large IgM class anti-A and anti-B antibodies can bind more RBC’s than the smaller IgG class.
