Full Study Name

Outcomes AlloMap Registry (OAR) Study (IRB no. 37479)


The purpose of this study is to create a research registry based on heart transplant recipients. A research registry is a collection of information about patients who have a particular disease or condition, or who receive a particular treatment, to be used for future research studies. This registry will allow researchers to observe the clinical long-term management and outcomes of heart transplant recipients with the regular use of AlloMap testing.

The AlloMap blood test, which has been approved by the U.S. Food and Drug Administration, is intended to help determine if a heart transplant recipient has a low probability of acute rejection at the time of testing.
