Reflections on Cultural Preferences and Internal Medicine: The Case of Jehovah's Witnesses and the Changing Thresholds for Blood Transfusions.

Jehovah's witnesses oppose receiving blood transfusions based on religious grounds. This refusal raises complex medical, legal and ethical issues for the treating medical staff.

This article will further discuss these current trends.
