Question 24

type one hypersensitivity

Answer 24

reaction occurs immediately, and involves ige

Question 24

type one hypersensitivity

Answer 24

reaction occurs immediately, and involves ige

Question 25

type two hypersensitivity

Answer 25

aka cytotoxic hypersensitivity, involved igg and igm and results in the destruction of the tissue that has the antigen on it
