Include your name and complete e-mail address in the body of the e-mail, and confirm that you would like to register for the LearnTransfusion series. You will then receive weekly email notifications of upcoming series events with details on how to join the webinars (e.g., call-in number and a link to register for the webinar).

The LearnTransfusion series is the seminar component of the Areas of Focused Competency (AFC)-Diploma Program in Transfusion Medicine. The series, organized by Canadian Blood Services is also open to all practitioners in the field of Transfusion Medicine. Through a series of regular webinars, trainees and practitioners are exposed to various scientific, technical and clinical aspects of transfusion medicine.
