A calculated measurement in which the number of T cells in a specified sample of blood is divided by the total number of lymphocytes in the sample, and the result presented as a ratio, fraction, quotient or percentage. T cells are thymus-dependent lymphocytes, that is, those that pass through or are influenced by the thymus before migrating to tissues, and are responsible for cell-mediated immunity and delayed hypersensitivity, as well as, in some cases, activating and deactivating other immune cells.
