Using such microcapsules, B cells and/or T cells can be selectively measured separately or simultaneously, in a simple manner, based on cell-mediated immunity which comprises applying the microcapsules sensitized with antibody to antigen of lymphocyte and sheep red cells or another kind of antibody-sensitized microcapsules that are optically distinguishable from the first antibody-sensitized microcapsules, to lymphocyte at the same time and thereafter independently measuring respective cells that are optically distinguishable from each other.The operation for the measurement is extremely simple and neither skill nor special equipment is required.Other References
