8. Variation in the strength of agglutination on the antibody identification panel may be observed.
What are two possible explanations for this variation? 9. Would you expect the autocontrol to be
negative or positive in the presence of the following antibodies? Why? 10. To rule out additional
antibodies when interpreting the results of an antibody parsel, the antigens present on the reactive
/ (non-reacive) (encircle your answer) cells are crossed out. 11. When matching the pattem of
reactions, only non-reactive cells heterozygous/ homoxygous for a particular antigen are crossed
out. 12. List at least three factors which contribute to the frequency at which different antibodiet
are produced. 13. Why is it important to use an antibody identification panel containing at least 10

and anti-E?.
