This is what the WTS calls primary components. To be a blood fraction in the WTS terminology it would have to be something that is only part of the above.
Note this chart:http://www.ajwrb.org/images/hlc2.jpg The first tier are the primary components and procedures that are not allowed.
The second tier are the fractions of those primary components and the procedures that ARE allowed.
XQ, you could call it a "fraction" but if the WTS does not agree with you, they would consider that you had DA'd yourself.
I am not arguing with you personaly or ajwb, but that chart is dated. THe watchtower allows blood to be removed from the body medicated and put back in. Such as for isotopic tracers.
And how do you answer hemogloulin fractions that contain more hemoglobin than packed RBCs? THe fraction is more of a "primary component" than the banned treatment. Thats like weighing a pound of chicken with bones vs a pound of boneless chicken. Think of it how will a JW reconcile that? I cant. Plasma is totally okay in context too. Platelete fibrin is okay. The only thing that you may have problems with is WBCs, but there are less wbcs in the blood than any of the allowed components other than clotting factor.
THe basically have changed the blood policy by not changing the blood policy. Now that you can't (or at least not suppossed to) ask if the person took any blood products nobody can investigate you. Sure there are people that will not take the four whole classes, but many will be free to take blood and not be penalized for it. Think about how many JWs commit fornication and as long as they keep the secret nobody knows. Now think about blood there is less in the bible about whole blood than fornication. How many rational jws will decide to compromise simply based on the confusion defense. "Well the DR said this part is less than that other part so I took it by aciddent".
Also it is not like the watchtower cares about individuals. That is for the locals to deal with. If several thousand JWs take blood and nothing happens to them it makes a better case PR wise. So even if they are reproved or unofficially shunned the watchtower benifits both ways. Plus how can the elders find out if they are not to talk to you about blood? Can anyone answer that. I am not being cynical I just want to know. If they are told in general to stay out of the medical end the only way I see it is if a jw nurse reports you. Even then they may df the nurse for gossip if the wt laywers think it is best. It would be odd if the blood issue starts to behave like the pedophile scandal. I can see it now a secret list of all the jws that recived blood with out reprisal. Famillies sueing because a family member died for a paper tiger.
