The tail suspension test (TST) is an experimental method used in scientific research to measure stress in rodents. It is based on the observation that if a mouse is subjected to short term inescapable stress then the mouse will become immobile. It is used to measure the effectiveness of antidepressant-like agents but there is significant controversy over its interpretation and usefulness.
