PROBLEM TO BE SOLVED: To provide a method for detecting cell-mediated immune response activity via enhanced effector molecule production.SOLUTION: A method for measuring cell-mediated immune response activity in a subject comprises steps of; bringing a source of T-cells from the subject into contact with an agent which modulates the function or activity of T-cells or a subset thereof and an antigen to which the cell-mediated immune response is to be tested; and measuring the presence or elevation in the level of an immune effector molecule from T-cells, where the presence or level of the immune effector molecule is indicative of the level of cell-mediated responsiveness of the subject.
