suppression test

A test or assay–eg, dexamethasone suppression test, used to determine whether a substance–hormone or protein being produced in excess is under the control of regulating or releasing factor(s), and therefore responsive to a feedback loop, or whether the excess production is autonomous, and not under feedback control. Cf Stimulation test.
