Stella T. Chou, MD, is board certified in Blood Banking/Transfusion Medicine and Hematology/Oncology and is an attending physician in the Division of Hematology and the Apheresis Program at Children's Hospital of Philadelphia. She specializes in caring for children with sickle cell disease, those who make antibodies against red cell transfusions (alloimmunization), and those requiring apheresis. Her research interests are focused on improving red blood cell matching for patients through the use of innovative tools.
Dr. Chou earned her medical degree from New York Medical College in Valhalla, New York. She completed her internship and residency in pediatrics at CHOP, as well as a fellowship in pediatric hematology/oncology. She also completed a fellowship in transfusion medicine at Hospital of The University of Pennsylvania in Philadelphia.
In addition to her clinical work, Dr. Chou serves as an Associate Professor of Pediatrics at the Perelman School of Medicine, University of Pennsylvania.
Dr. Chou’s research efforts are centered on investigating the mechanisms of normal hematopoietic development and how these become disrupted in hematologic diseases. Her research interests also include alloimmunization in patients with sickle cell disease. Her current research in this area focuses on alloimmunization prevention and transfusion safety using genomics to identify risk for alloantibody formation and selecting compatible blood donors.
“Because transfusion therapy remains a critical treatment for hemoglobinopathies, my goal is to identify new approaches to minimize alloimmunization, reduce complications and improve therapy,” she says.

The Patient Experience Rating is an average of all responses to the care provider related questions shown above from our nationally-recognized Press Ganey Patient Satisfaction Survey. Patients that are treated in outpatient or hospital environments may receive different surveys, and the volume of responses will vary by question.
Responses are measured on a scale of 1 to 5 with 5 being the best score.
We are committed to true transparency. However, to ensure the comments are fair and correctly attributed, we review each one before posting to the website. We exclude entire comments that disclose patient's protected health information, are off-topic, or include other confidential or inappropriate content. Comments will appear on provider bios only if providers have a minimum number of comments.
Comments are shared internally for education purposes to ensure that we are doing our very best for the patients and families for whom we are privileged to care.
The comments are submitted by patients and families and reflect their views and opinions. The comments are not endorsed by and do not reflect the views of Children’s Hospital of Philadelphia.
