  4. Add one drop of blood to each well of the blood typing tray. • Make sure that you work quickly and there is enough blood that it does not dry to the tray. • Clean the tip of your finger with a new sterile alcohol pad and dispose of it in the biohazard bag. • Add one drop of anti-A serum to the A well, one drop of the anti-B serum to the B well, and one drop of anti-Rh to the Rh well. • Using a clean toothpick, stir the A well thoroughly. Dispose of the toothpick in the biohazard bag.

  5. Repeat step 10 for B and Rh wells. Be sure to use a new toothpick for each well to avoid cross contamination. • Examine each well for agglutination. Agglutination indicates a positive test result. • Record your results in Table 1 and determine your blood type. • Pool the class data and calculate the percentage of students with each blood type using the following formulas: Total number of students with type (x) blood X 100 Total number of students in class • Record your results in Table 2.
