  Methods are described for assaying human and mammalian immune system function. Methods for determining the reserve capacity of a subject's immune system to provide amplifier and suppressor responses are described, together with methods for titrating dosage amounts of agents modifying immune response. In the preferred embodiments, IL-2 or G-IFN production are used to measure positive (i.e., amplifier) immune capacity or reserve, and cell proliferation is used to measure negative (i.e., suppressor) immune capacity or reserve.
