What type of immune reaction is IgE mediated and involves the degranulation of mast cells?
Type I
What type of immune reaction is IgG/IgM mediated and involves antigen-antibody complex formation on the cell surface?

B cells
what type of immune reaction is cell mediated?
Type IV is cell mediated and involves T cells
An atopic reaction indicates:
a genetic predisposition
What is an example of a Type II sensitivity reaction?
Hemolytic disease of the newborn
