Top Trending Hypersensitivity Quizzes

Why Am I So Hypersensitive? Take This Immune Reaction Quiz

Do you often wonder, "Why am I so hypersensitive?" to certain triggers like allergens, medications, or insect stings? This engaging quiz will help you understand how your immune system reacts to different...

Questions: 12 | Attempts: 2123 | Last updated: Nov 11, 2025

Sample Question 1
Leprosy is caused by Mycobacterium leprae. The lepromin skin test detects which type of hypersensitivity reaction?

Type I

Type IV

Type II

Type U or 111

Type III

Sample Question 2
The main difference between Type II and Type III hypersensitivity is:

The class (isotype of antibody)

Whether the antibody reacts with the antigen on the cell or reacts with antigen before it interacts with the cell

The participation of complement

The participation of T cells

Delayed Defense: Type 4 Hypersensitivity Quiz

Questions: 15 | Attempts: 11 | Last updated: Mar 19, 2026

Sample Question 1
What is the primary distinguishing feature of Type IV hypersensitivity compared to Types I, II, and III

It is mediated by IgE antibodies and mast cells

It is the fastest hypersensitivity reaction occurring within seconds

It is mediated by T cells rather than antibodies and typically peaks 48 to 72 hours after antigen exposure

It exclusively involves complement activation and neutrophil recruitment

Sample Question 2
Contact dermatitis caused by poison ivy or nickel is a classic example of Type IV delayed-type hypersensitivity

True

False
