How Estimated Post Transplant Survival score is calculated and used
Learn about the EPTS score
An Estimated Post Transplant Survival (EPTS) score is assigned to all adult candidates on the kidney waiting list and is based on four factors:
- Candidate time on dialysis
- Current diagnosis of diabetes
- Prior solid organ transplants
- Candidate age
A candidate's EPTS score can range from 0% to 100%. The candidates with EPTS scores of 20% or less will receive offers for kidneys from donors with KDPI scores of 20% or less before other candidates at the local, regional, and national levels of distribution. The EPTS score is not used in allocation of kidneys from donors with KDPI scores greater than 20%.
