Transfusion Medicine and Cellular Therapy

Our Transfusion Medicine and Cellular Therapy Laboratories include the Blood Bank, the Cellular Therapy Laboratory, and the Apheresis Center

We have three board certified physician medical directors and more than 50 licensed medical technologists, technicians, and registered nurses. Our Blood Bank operates 24 hours a day, seven days a week, providing more than 45,000 units of blood, platelets, and plasma for transfusion every year. Our laboratories are licensed by the New York State Department of Health. Our facilities are also accredited by the American Association of Blood Banks (AABB), the College of American Pathologists, and the Foundation for the Accreditation of Cellular Therapy. The Transfusion Medicine and Stem Cell Therapy laboratories also participate in numerous studies requiring apheresis stem cell collections and immunohematology laboratory testing.


The Blood Bank supports both the inpatient and outpatient transfusion services at Mount Sinai with immunohematology testing, and by providing blood, plasma, platelets, and other products for transfusion. 

The Blood Bank Laboratory staff performs testing and prepares blood products to ensure the safest possible transfusion for our patients. Testing includes blood ABO/Rh typing, screening for possible transfusion reaction-related antibodies, and cross matching blood units in preparation for transfusion. We use the most advanced methods of testing, with automation designed to provide rapid, accurate test results.

Our Medical Directors include three physicians who are board certified in Blood Banking and Transfusion Medicine. We also have more than 40 licensed medical technologists and technicians on staff. The Blood Bank operates 24 hours a day, seven days a week. More than 200,000 tests are performed and we prepare more than 45,000 units of blood, platelets, and plasma for transfusion every year.

We are licensed by the New York State Department of Health, with accreditations from the AABB, the College of American Pathologists (CAP), and the Foundation for the Accreditation of Cellular Therapy.

A Note to Patients on Blood Donations

The Mount Sinai Health System relies entirely on voluntary blood donations from carefully screened voluntary donors. All blood donated for transfusion undergoes extensive testing in compliance with U.S. Food and Drug Administration regulations.

Some patients prefer to donate their own blood for transfusion, as part of their preparation for elective surgery. This is known as autologous blood donation, and we encourage it whenever possible. For some patients, autologous blood donation will not be possible, due to their age, medical status, or the timing of surgery. In this setting, family members or friends may donate blood for a patient to use, known as directed blood donation.

If you would like to arrange for autologous or directed blood donations, contact your physician to arrange the donation through the New York Blood Center, which has donor collection centers throughout the metropolitan area. Autologous and directed blood donations require special handling, for which the Blood Center charges a fee. At least five working days are needed to test, process, and ship the blood to Mount Sinai. For information on autologous and directed donations or to schedule a donation, contact the New York Blood Center or call (800) 439-6876.

The Cellular Therapy Laboratory (CTL) supports busy adult and pediatric bone marrow/stem cell transplant and multiple myeloma programs at the Mount Sinai Health System, which performs more than 160 transplants annually. Our laboratory is responsible for processing, storing, transporting, and assisting with the infusion of cellular therapy products (also called stem cell products) used for autologous and related and unrelated allogeneic transplantation. These processes are regulated by the U.S. Food and Drug Administration, and accredited by the Foundation for the Accreditation of Cellular Therapy and the American Association of Blood Banks. 

We have successfully passed numerous regulatory/accrediting inspections (FACT, NYSDOH, AABB, and CAP), and the CTL team has been honored with a “Recognition of Excellence Award.”

Cellular Therapy Clinical Services 

The staff of the Cellular Therapy Laboratory performs a range of procedures and services, including the following:

  • Processing bone marrow and peripheral stem cells, including procedures such as volume reduction, red cell and plasma reduction, washing of cells to remove cryoprotective media, and more complex procedures. Storage involves the addition of cryoprotective media to products, followed by controlled rate freezing and placement into the vapor phase in liquid nitrogen freezers.
  • Processing and cryopreserving donor lymphocytes to be used for patients who had a prior allogeneic bone marrow or peripheral blood stem cell transplantation.
  • Delivering cryopreserved, reconstituted, or washed products to the recipient’s bedside (both inpatient and outpatient). Our lab has the responsibility for the thawing of the cryopreserved products at the bedside.
  • Arranging shipment of patients’ products to and from other hospitals at a patient’s and physician’s request

The Cellular Therapy Team 

Our Cellular Therapy staff members are passionate, skilled, and specially trained professionals. All members of our CT team meet the regulatory and accrediting requirements.
