EPTS Calculator — Estimated Post-Transplant Survival
Estimate a kidney transplant candidate's expected post-transplant survival percentile from four inputs (recipient age, diabetes, prior solid-organ transplant, and years on dialysis) using the OPTN EPTS model that drives longevity matching in deceased-donor allocation.
When to use it
Use during transplant evaluation and organ-offer decisions to gauge recipient longevity benefit and to see whether a candidate qualifies (EPTS at or below 20 percent) for priority allocation of the highest-quality (KDPI at or below 20 percent) donor kidneys.
Formula
Inputs: recipient age (years), diabetes (yes/no), prior solid-organ transplant (yes/no), and years on dialysis. The raw score maps to a national percentile from 0 to 100 percent; a lower EPTS means longer expected post-transplant survival.

Common clinical questions
- What EPTS score qualifies a candidate for the best donor kidneys?
- A candidate with an EPTS at or below 20 percent is prioritised for the highest-quality donor kidneys (KDPI at or below 20 percent) under longevity matching, aligning long-expected recipient survival with long-expected graft survival.
