Why Yale Medicine?
  • We are one of four national centers conducting a clinical trial that studies blood transfusion safety.
  • We use platelet blood products that have been specially treated to eradicate any emerging infectious diseases, such as the Zika virus.
  • All staff undergo regular training on best practices of blood transfusions.

You never know when you may need a blood transfusion. Transfusions occur when a blood from a donor is infused into a patient. This usually happens when certain components of the patient’s blood, such as red blood cells or platelets, become too low. 

“Transfusions are as safe now as they’ve ever been in the era of modern medicine,” says Jeanne Hendrickson, MD, associate professor of laboratory medicine and of pediatrics at Yale School of Medicine and associate director of the Yale Blood Bank. While blood transfusions are life-saving treatments, like all medical procedures, they come with some risks. Physicians and staff at Yale Medicine take additional measures to ensure safe transfusions.
