A member asked:
What is the difference between type i hypersensitivity and type ii?
A doctor has provided 1 answer
Big difference: Type 1 is mediated by the IgE antibody and responsible for anaphylaxis, hay fever, allerg etc. Allergy skin test can identify these. Type 2 is mediated by IgG or IgM antibody and complement proteins that are "cytotoxic" that ends up killing the target cell. Examples of this are hemolytic anemia, Graves disease, Myasthenia gravis, Rheumatic heart disease, etc. For anemia, a Coombs test is used
