“I will only accept blood from my own veins or from my Aunt Margo! That’s it!” Autologous and directed blood donations happen much less often in 2019 than in the past, but Julie Karp is here to tell us if they should still happen at all!
Back in the 1980’s, HIV was a newly discovered virus and we had no test for the virus we now know as hepatitis C. Patients back then were very interested in making blood transfusion as safe as possible. As a result, the frequency of both autologous and directed donations increased dramatically! However, HIV transmission through blood is now spectacularly rare, and blood has never been safer from viruses. Does it still make sense to pursue either type of blood donation? In this interview, Dr. Karp explains the pros and cons of these “special blood collections,” and shows us why they are not always a great idea. She also outlines situations where either type of donation might still actually be helpful.
Obviously, if mom’s an O and daughter’s an A, I’m not giving daughter’s A blood to mom. I don’t care how much you love her! Hemolysis doesn’t care!
ABO, unfortunately, trumps love!
