Molecular Pathology Laboratory

The primary mission of the Molecular Pathology Laboratory at NewYork-Presbyterian/Weill Cornell Medicine is to provide the best clinical molecular diagnostic services for the clinicians and pathologists providing care to patients at NewYork-Presbyterian.  Since its inception, this laboratory has been developing and performing state-of-the-art molecular-based tests to aid in the diagnosis and management of infectious disease, genetic disorders, solid tumor malignancies and monitoring transplant, working closely with clinicians, pathologists and health care professionals.  The laboratory is directed by Hanna Rennert, PhD, FACMG, with ten staff members (a PhD technical specialist, supervisor and laboratory technologists).  The laboratory is CLIA-certified and accredited by New York State Department of Health and the College of American Pathologists.
