No Effect of Delayed Cutaneous Hypersensitivity Testing (Multitest) on Blood Lymphocyte Counts and Functions

Abstract
The effects of delayed cutaneous hypersensitivity (DCH) testing (Multitest) on lymphocyte counts and functions were studied in 7 healthy women. All had normal DCH responses and lymphocyte functions. No influence of the DCH testing on subsequent tests for lymphocyte subpopulations and mitogen- and antigen-induced DNA synthesis was observed. The PPD [purified protein derivative] skin test did not boost or otherwise alter the in vitro lymphocyte response to PPD. Multitest is a simple way of assessing DCH and does not interfere with repeatd in vitro tests of lymphocyte capacity.
