Dr. Kevin Land, Senior Medical Director for Field Operations at Blood Systems International, joins Dr. Chaffin for an episode of “Blood Bank MythBusters!” Like urban legends, many things in transfusion medicine are taken for granted as absolute truth, when in fact some of those “facts” may not be totally true (if at all). Dr. Land, who has extensive experience consulting with both hospitals and blood centers on best practices, takes an interesting and sometimes hilarious look at four of those beliefs, and (SPOILER ALERT!) flat-out busts some of them as myths!

Here are the four beliefs Dr. Land and Dr. Chaffin discuss:

  1. The biggest risk from transfusion is getting a viral disease
  2. Donors with type O-negative blood are universal blood donors and their blood is safe for everyone
  3. Blood is bad! Transfusing leads to increased mortality
  4. Younger, fresher blood is better than older, stored blood
