This is a sample calculator to show how the lung allocation score (LAS) is established. It uses the same formula as the one transplant hospitals use to enter data on patients on the waiting list for a lung transplant.
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.
