They were edging towards a change when they allowed the option of blood fractions. Practically, this could be whole blood (i.e. all the fractions), but JWs can't see it. As one told me (about this change), 'The Bible hasn't changed, but Science has'... I don't understand that, but to be honest, I don't believe they knew what they were talking about either, which is the norm for the majority of JWs (they just seem to repeat any garbled 'excuse' for changes in doctrine). If whole blood is separated and then administered, a JW will see it as allowable blood fractions (even if it's all the fractions) and not whole blood. I mentioned on a (old) thread, that perhaps the WT will 'get around' the blood issue by allowing a transfusion of whole blood IF something is added (eg. saline) which JWs would easily accept as not being whole blood (as it has an addition)
