Though Jehovah's Witnesses do not accept blood transfusions of whole blood, they may accept some blood plasma fractions at their own discretion. The Watch Tower Society provides pre-formatted durable power of attorney documents prohibiting major blood components, in which members can specify which allowable fractions and treatments they will personally accept. Jehovah's Witnesses have established Hospital Liaison Committees as a cooperative arrangement between individual Jehovah's Witnesses and medical professionals and hospitals.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who do most Witnesses get guidance from in regards to how much blood plasma fractions they are willing to accept?
