JW & Blood

Independent information on Jehovah’s Witnesses and their blood doctrine

Blood components, fractions and whole blood

A transfusion can use a blood component. Ending the ban on components therefore changes which transfusions Witnesses may accept.

Whole blood
Blood containing plasma and blood cells together. Transfusions of another person’s whole blood remain prohibited under the September 2026 policy.
The four main components
Red cells, white cells, platelets and plasma. Since 18 September 2026, Witnesses may decide for themselves whether to accept these from a donor.
Blood fractions
Products extracted from components, such as albumin and clotting factors. These were already left to individual conscience before the September announcement.
