A noninvasive genetic test developed by researchers at the Howard Hughes Medical Institute and Stanford University in Stanford, Calif, could help physicians forego heart biopsy to monitor the health of a transplanted heart (Snyder TM et al. Proc Natl Acad Sci U S A. doi:10.1073/pnas.1013924108 [published online ahead of print March 28, 2011]). The test detects DNA from the donor's genome circulating in the blood of the transplant recipient.
