Grading Aggulutination Reactions Quiz (tube and Gel)

1. Many small clumps with a cloudy background. Grade the reaction 

2. No clumps with a very cloudy background. Grade this reaction 

3. Agglutinated cells begin to disperse into gel media and are concentrated near the top of the microtube. Grade the reaction.

4. All cells pass through the gel media forming a cell button at the bottom of the microtube. Grade this gel reaction.

5. Medium clumps with a slightly cloudy background. Grade the reaction.

6. Solid button with clear background. Grade the reaction.

7. Agglutinated cells disperse throughout the gel media and concentrate towards the bottom of the microtube. Grade the reaction.

8. Large clumps with clear background. Grade the reaction.

9. Agglutinated cells disperse into gel media and are observed throughout the length of the microtube. Grade this gel reaction.

10.  Agglutination cells form a cell layer at the top of the gel media. Grade the reaction.
