    Area of Science:

    • Immunology
    • Dermatology

    Background:

    • Delayed cutaneous hypersensitivity (DCH) testing is a key method for evaluating T cell-mediated immunity.
    • Skin testing assesses an individual's immune response to specific antigens, aiding in the diagnosis of anergy or immunologic deficiencies.

    Purpose of the Study:

    • To review the current applications and challenges of delayed cutaneous hypersensitivity testing.
    • To highlight the importance of DCH testing in clinical immunology and diagnostics.

    Main Methods:

    • Review of existing literature on DCH testing.
    • Discussion of antigen selection, administration techniques, and interpretation of results.

    Main Results:

    • DCH skin testing evaluates T cell immunity and can identify causative organisms or immunologic deficiencies.

  • Commonly used antigens are ubiquitous, safe, cheap, and effective, eliciting characteristic skin lesions upon intradermal injection.

    • Conclusions:

    • Despite issues with false reactions, standardization, and antigen batteries, DCH skin testing is a valuable, accessible tool for immune system assessment.
    • Ongoing research aims to improve reliability and develop alternative antigens for more accurate DCH assessment.
