AlloMap Testing Process

The AlloMap® test starts with a simple blood draw. Your transplant care team and CareDx® can provide information on the test site that is closest to you. Once the blood sample is collected, it is sent to the CareDx clinical laboratory for testing. AlloMap results are available within 1-2 days after the sample arrives at CareDx and results are sent directly to your doctor and transplant center. Your doctor will follow up with you to discuss your results.

Talk to your doctor about making AlloMap testing part of your transplant care. If AlloMap is right for you, your doctor will:

  • Order an AlloMap test.
  • Direct you to a draw site nearby to have your blood drawn. This may be the same lab that you go to for other blood draws or a different facility.
  • Have the draw site collect, process, and send your blood sample to CareDx.
  • Receive your AlloMap test results, usually within 2 days after processing by CareDx.
