Elective Number: 2307 (arranged) NOT OFFERED IN 2016-2017

Rotation Supervisors: Drs. Pamela Clark, Gay Wehrli and Blood Bank Fellow

Coordinator: Dr. Clark, Old Medical School, room 3810

Duration: 2 weeks

Available:

Report to: Blood Bank

Time to Report: 11:00 am

Place to Report: Blood Bank

Typical day: 9:00 am - 5:00 pm

Attendance: Attendance at elective activities is mandatory.

  • Anyone who is ill or has a personal or family emergency must contact Student Affairs and the Attending on Service.
  • Students are allowed to take off up to 1 day per week to interview between November 1 and February 1.
    • Specific days missed must be approved by the Attending on Service.

Number of students per rotation:

Course Description: The student will participate in the consultative activities of the Transfusion Medicine Service including investigation of transfusion reactions, immunohematologic problems, and blood component therapy. The student will have the opportunity to learn about the collection, preparation, processing, and storage of blood and blood components, pretransfusion testing, red cell/platelet alloantibody and autoantibody identification, and other specialized laboratory evaluations. Teaching sessions devoted to areas of controversy, recent advances, and patient management will be directed toward the student's planned field of practice.

Morning Rounds: Monday - Friday - 11:00 in the Blood Bank
