2. Touch your finger; that has a large drop of blood on the end of it, to the drop ofanti-Rh serum. Wipe your finger with the alcohol ball and dry with a cotton ball. Stir the anti-Rh and blood mixture with a clean toothpick.

3. Place the microscope slide on the slide warming box. Rock the box gently and observe the slide for clumping. If the blood clumps in the anti-Rh serum within two minutes, you have Rh positive blood.
