Hematopathology Consultation Service
Nancy Rosenthal, MD and Sergei Syrbu, MD, PhD and Carol Holman, MD, PhD
A national anatomic and clinical pathology reference laboratory
affiliated with UI Health Care


The Hematopathology Service focuses on the diagnosis of hematolymphoid disorders from the bone marrow, lymph nodes, and other lymphoid tissues. In addition to a comprehensive morphologic interpretation ancillary studies are available to support diagnostic interpretations. These include immunohistochemistry, flow cytometry, cytogenetics, and molecular pathology.

Under the direction of Nancy Rosenthal, MD, the service has three very experienced hematopathologists. There are approximately 1800 specimens processed per year with approximately 600 solid lymphoid tissues and 1200 bone marrow specimens.  The pathologists work closely with consulting pathologists and oncologists to orchestrate the necessary diagnostic procedures, and integrate the information generated for a comprehensive diagnosis.
Turnaround Time: Routine timeframe for turnaround is 2-5 days.
