We are currently making updates and improvements to the OPTN website. Data dashboards, calculators, and other interactive tools will be back online as soon as possible.
Ongoing updates
CPRA calculator
The Calculated Panel Reactive Antibody (CPRA) calculator is used to evaluate candidates for kidney, pancreas and kidney/pancreas transplants.
EPTS calculator
An Estimated Post Transplant Survival (EPTS) score is assigned to all adult candidates on the kidney waiting list, as part of the new kidney allocation system.
KDPI calculator
The Kidney Donor Profile Index (KDPI) calculator summarizes the risk of graft failure after kidney transplant.

This is a sample calculator to show how the lung Composite Allocation Score (lung CAS) is established. It uses the same formula that is used for the lung allocation policy that took effect on March 9, 2023.
