Trifecta-Heart cfDNA-MMDX Study: Comparing the DD-cfDNA Test to MMDx Microarray Test and Central HLA Antibody Test

The current standard for assessment of rejection in heart transplants is an endomyocardial biopsy (EMB) interpreted by histology according to ISHLT guidelines. This has considerable error rates, many due to the high disagreement among pathologists in assessing lesions and diagnoses. To address the unmet need for precision and accuracy, the Alberta Transplant Applied Genomics Centre (ATAGC, University of Alberta) has developed a new diagnostic system - the Molecular Microscope® Diagnostic System (MMDx), which uses microarrays to define the global gene expression features of rejection and injury…
