[Types of immunocompetent cell reactions in in vitro loading tests in healthy children]

Lymphocyte reactivity was assessed with various surface antigens detectable by Russian monoclonal antisera by indirect immunofluorescence in peripheral blood samples from 40 healthy children in vitro in loading tests. Values of a coefficient reflecting individual reactivity of immunocompetent cells with surface antigens CD5, CD4, and CD8 corresponding to type II reaction were found characteristic of children whatever their age or sex. The results may be used as reference values in examinations of children with various diseases.
