actually, the society changed its' blood policy several years ago without telling the R & F. Hemoglobin transfusions were a disfellowshipping offense until I believe 2000. That's when the new policy about the main components went into affect. I found out about it in 2002 by accident (an elder who has contact with the Hospital Liaison Committee informed him). Checked it out on the Ajwrb.org and saw a video where a spokesman for the society in the Netherlands stated that the society was getting away from deciding on fractionated blood components. Hence products like hemopure could now be taken without fear of reprisal from the organization at that time. In 2004 the society makes public it's new policy to the R & F.
