Which type of hypersensitivity reaction involves immune
complexes formed when antigens bind to antibodies?
a) Type III
Type III hypersensitivity is associated with systemic lupus
erythematosus, rheumatoid arthritis, serum sickness, certain types of
nephritis, and some types of bacterial endocarditis.
b) Type I
Type I or anaphylactic hypersensitivity is an immediate reaction,
beginning within minutes of exposure to an antigen.
c) Type II
Type II, or cytotoxic, hypersensitivity occurs when the system
mistakenly identifies a normal constituent of the body as foreign.
d) Type IV
Type IV, or delayed-type, hypersensitivity occurs 24-72 hours after
exposure to an allergen.
