[The lymphocytotoxic test as a method of identifying subpopulations of T lymphocytes using monoclonal antibodies].

The authors analyse the findings of the lymphocytotoxicity test with monoclonal antibodies and the indirect immunofluorescence method used for the assays of T lymphocyte subpopulations. The mean values of the total count of T lymphocytes, T helpers, T suppressors, as well as the immunoregulation index obtained by both methods have proved practically the same. The lymphocytotoxicity data have been in good correlation with the findings of indirect immunofluorescence in tests with all the monoclonal OCT antisera.
