Recent change in religious guidance expands individual decisions on use of one’s own blood in medical and surgical treatments, while maintaining historical restrictions and reigniting ethical and legal debates involving religious freedom, patient autonomy, and doctor involvement in critical situations.
The Jehovah’s Witnesses announced a significant change in one of their most well-known and controversial medical guidelines.
As of an update released on March 20, 2026, members can now individually decide whether to authorize the withdrawal, storage, and subsequent reinfusion of their own blood in medical and surgical procedures.
However, the prohibition against receiving blood from others has been maintained by the organization.

The guidance was presented by Gerrit Lösch, a member of the Governing Body of the religion, in a statement published on the group’s official website.
According to the new formulation, each Christian must decide how their own blood will be used in medical care, including in situations where it may be withdrawn, stored, and returned later.
In practice, the change opens the door for pre-planned autologous procedures, something that had been rejected by doctrine for decades.
Use of own blood in surgeries and medical treatments
The change does not eliminate the religious basis that supports the refusal of allogeneic transfusions, that is, with blood from donors.
In the medical material maintained by the organization, Jehovah’s Witnesses continue to assert that they do not accept blood transfusions from third parties and that they record their decisions in advance directives.
At the same time, the group had already admitted, prior to this revision, some techniques for managing one’s own blood, such as hemodilution and intraoperative recovery, as long as they were compatible with the individual patient’s conscience.
With the new guidance, scheduled procedures gain a broader decision-making space for members of the religion.
In an elective surgery, for example, the patient can now consent to have their blood collected before the intervention, stored, and reused afterward.
Previously, the organization’s literature treated the prior storage of autologous blood as incompatible with the biblical interpretation adopted by the group.
Still, the flexibility has limited reach.
It does not alter the refusal of the four main components of blood from others, nor does it resolve the impasse in emergency situations, when a donated transfusion may be considered by the medical team as the quickest or most effective measure to prevent death.
Therefore, although it represents an important inflection in institutional discourse, the change does not end the historical conflict over blood transfusions.
The organization itself describes the revision as a clarification on the use of the patient’s own blood.
At the same time, the doctrine continues to be presented as derived from biblical passages that advocate abstention from blood.
This helps explain why the group considers the new measure a decision of conscience within a theological limit that remains preserved.
Number of members and global impact of the decision
The most recent data released by Jehovah’s Witnesses themselves indicate a global contingent of over 9.2 million publishers in the 2025 service year.
In Brazil, the organization reports 938,337 ministers who teach the Bible and more than 12,000 congregations.
These numbers exceed the rounded estimates that often circulate in journalistic texts.
The statistical update is relevant because it shows the extent of a decision that affects a significant universe of believers.
As a consequence, the impact also reaches hospitals, medical teams, and courts.
In public and private health systems, the relationship between patient autonomy, religious freedom, and professional responsibility had already been strained in concrete cases.
Judicial decisions on blood transfusion in Brazil
In the country, the topic gained clearer contours following the judgment of the Supreme Federal Court in September 2024.
On that occasion, the Court recognized that adult and capable patients can refuse blood transfusions for religious conviction.
The STF also established the possibility of alternative treatment funded by the public authority.
For this, criteria such as technical feasibility, medical agreement, and free and informed expression of the patient must be respected.
This understanding helped to support subsequent decisions.
In November 2025, a patient from Campinas obtained a court order for the SUS to fund a bone marrow transplant without blood transfusion.
The case was considered relevant as it involved public funding for a procedure outside the traditional network.
Just a few months later, in January 2026, the São Paulo Court of Justice denied compensation to the family of a young woman who received a transfusion without authorization in a public hospital.
According to the court, the patient presented a severe condition, and the medical team adopted the procedure as it was deemed essential to try to save her life.
The decision reinforced the legal weight of the right to life in situations of imminent risk.
Criticisms and limits of the new religious rule
The revision announced by the religious leadership also reignited criticisms from former members and observers.
For this group, the authorization to store and reuse one’s own blood only corrects part of the historical rigidity of the doctrine.
In the assessment of these critics, the main problem remains in emergency situations, when the use of blood from others can be decisive.
Thus, the change expands the margin of choice in planned surgeries. On the other hand, it keeps intact the most sensitive point of the debate involving the risk of death.
The new rule is likely to produce immediate effects on hospital protocols and consent forms.
It should also influence the planning of elective surgeries in different countries. Still, it preserves the core of the prohibition that made the religion widely known in public debate.
