Rising levels of donor DNA in recipients' blood could mean the organ is in danger.
A new test could provide a noninvasive way of monitoring heart transplant patients for organ rejection. The test, which relies on DNA sequencing to detect fragments of the donor's DNA in the recipient's blood, still needs to be validated in clinical trials. But physicians hope it will ultimately offer an easy way to detect the signs of organ rejection in all types of transplant patients, perhaps earlier than other approaches.
