A graphical presentation of counts of T lymphocyte subpopulations and Th-Ts ratios.
A method is described for the graphical display of the absolute number of two major subpopulations of blood T lymphocytes, the helper (Th) and the suppressor/cytotoxic (Ts) cells, and their ratio, the Th/Ts ratio. Such a display permits distinction between patients with a low Th/Ts ratio due to decreased numbers of Th cells, which correlates with in vivo tests for immunodeficiency and is seen in the acquired immune deficiency syndrome (AIDS), and patients with a low Th/Ts ratio due to increased numbers of Ts cells but no immunodeficiency by in vivo tests, as seen in some homosexual men who have had recurrent infections.
