Answer:
Procedure for Blood Typing Test:
1. Use the dropper vial to place a drop of Sample 1 synthetic blood in each well of the typing slide, ensuring the dropper vial is closed after each use to prevent cross-contamination.
2. Add a drop of synthetic anti-A serum (blue) to well A and close the cap.
3. Add a drop of synthetic anti-B serum (yellow) to well B and close the cap.
4. Add a drop of synthetic anti-Rh serum (clear) to well Rh and close the cap.
5. Use a different-colored mixing stick for each well (blue for anti-A, yellow for anti-B, and clear for Rh) to gently stir the synthetic blood and antiserum drops for 30 seconds. Use a separate stick for each sample to avoid contamination.
6. Carefully examine the resulting thin films of liquid mixture in each well. If a film is uniform, there is no agglutination. If the sample appears granular, agglutination has occurred.
7. Fill in the column for Sample 1 in the data table, indicating yes or no for agglutination with each antiserum.
8. Thoroughly rinse the blood typing slide and repeat steps 1 through 7 for synthetic Samples 2, 3, and 4.
Record the observations in the data table for each sample.
