Summary

This study is testing a non-invasive blood test that looks for donor DNA in the blood of heart and lung transplant patients. Higher levels of this DNA may signal early rejection before permanent damage occurs. About 991 participants aged 14 and older will provide blood samples over time to see if the test can predict rejection and improve long-term outcomes.
