CMV can cause BIG problems in certain susceptible transfusion recipients, but people disagree on prevention. Dr. John Roback has spent years at the heart of the debate, and he's here to help!

As far as I know, no studies with low birth weight infants and pathogen reduction technology have been done. Are you aware of any in progress?
I’m not, Dawn, but I’m also not someone who has my finger on the pulse of all the ongoing studies. I’m sure that is something that will be done at some point.

Joe: Just listened to this piece. Surprised you and John did not refer to the decision in Canada to discontinue CMV testing for any but intrauterine transfusions. It had been done already by the time of the podcast. In addition, there have been no CMV tested units at U Iowa (Strauss’s old shop) for decades. You are right and John is wrong :).
Louie, that’s a fair criticism (the Canadian decision), and all I can offer in my defense is I MEANT to ask about it (not a great defense…)!
