Estimated post-transplant survival (EPTS)

The Estimated Survival (EPTS) score is a numerical measure of 0% to 100% used to allocate some kidneys in the kidney allocation system.  Candidates with a lower EPTS score are expected to experience more years of graft function from high-longevity kidneys compared to candidates with higher EPTS scores. EPTS values are derived by comparing each candidate’s raw EPTS score to percentiles from a reference population consisting of all adult kidney patients on the (national) waitlist as of a recent date.
