Blood Typing: Lab Analysis/Comments

Blood Typing Lab:
We did a blood typing lab using simulated blood to learn how to determine the different kinds of blood based on the ABO system.



Sample #1 (Type A): Blue precipitate formed on the bottom of the slide in little flakes with the Anti-A serum. Nothing happened with the Anti-b serum.

Sample #2 (Type B): Orange precipitate formed when Anti-B serum, nothing happens with Anti-A serum.

Sample #3 (Type AB): Blue precipitate formed in small grains on the bottom of the slide when Anti-A serum was added, and yellow precipitate formed in small flakes when Anti-B serum was added.

Sample #4 (Type O): No change when either serum was added.
