Lung Allocation Score

Discover how your lung allocation score affects your lung transplant wait time at University Health.

Your Lung Allocation Score

The United Network for Organ Sharing (UNOS) prioritizes lung transplant patients by lung allocation score (LAS). The United Network for Organ Sharing (UNOS) manages the national waiting list and calculates and assigns your LAS. UNOS uses your LAS to estimate the urgency of your illness (need for a donor lung) and your probability of first-year success after a lung transplant.

Calculating Your LAS

Your LAS considers your blood work, test results and disease diagnosis from your lung transplant evaluation and testing. You’ll get a LAS between 0 and 100. A higher score means you have a higher priority on the waiting list.

Updating Your LAS

Expect information updates and some testing every six months at a University Health transplant clinic or your nearest transplant outreach clinic. We are required to update the UNOS waiting list regularly.

Your LAS will adjust as your lung disease changes. If your condition worsens, your transplant coordinator will update the UNOS system. The result may be a higher LAS and a higher priority for transplant for you.

If you have questions about your LAS, talk to your transplant doctor about your specific situation.
