Learn about LAS

Learn how your lung allocation score is calculated and used

The LAS calculator is a tool that can be used to estimate each lung candidates' medical urgency and expected post-transplant survival rate relative to other patients on the waiting list for a lung transplant. 

The LAS calculator cannot accurately predict how long any patient will live with or without a transplant. It is not a definitive measure of life expectancy on the waiting list or post-transplant survival. It does not include all factors that influence survival and does not take into account any quality-of-life benefit patients may receive from transplantation.

Talk to your physician or your transplant team about your specific situation.

When calculating the LAS, enter as much data as you can.
