Type O negative blood – every hospital wants a supply on its shelves. But with a prevalence of only seven percent within the population, this valuable resource must be managed with care. Dr. Mair will discuss ways to best utilize lifesaving type O negative red blood cells.


This activity has been designed for general, specialty and subspecialty physicians who prescribe blood products and for hospital transfusion service Medical Directors. There are no participant prerequisites for this activity.

CME CREDITS: 1.0 AMA PRA Category 1 Credit(s)TM


Enter Course

At the conclusion of this activity, participants should be able to:

  1. Identify O RhD– patients who are at lower risk for making an anti-D antibody after receiving O RhD+ red cells
  2. Describe ways to preserve the supply of O RhD- red cells for patients who need them
  3. Apply knowledge of AABB standards to providing RhD+ cellular products to RhD– patients

To receive CME credit for this activity, participants must:

  1. Acknowledge their review of activity prerequisites, objectives, disclosures, methods of physician participation and statements.
  2. Review the presentation "Type O Negative Red Blood Cell Utilization: Preserving this Rare and Lifesaving Resource" or read the PowerPoint slides and accompanying notes available as a printable Adobe Reader® file.
  3. Take the online Post-Test.
  4. Complete the online Activity Evaluation.
  5. Print the certificate awarding 1.0 AMA PRA Category 1 credit(s)TM through the SUCCESSTM program.
