title: Anergy and delayed hypersensitivity skin testing.
abstract: Delayed hypersensitivity skin tests, when properly planned and performed, are both practical and sensitive in determining the status of cell-mediated immunity. They can be diagnostic of specific exposure, such as tuberculosis, or they can rule out anergy. Pitfalls include poor selection of antigens, inappropriate application and poor timing of test interpretation. The transparent tape method is preferred for recording the results.
