Blood transfusion remains a cornerstone of modern healthcare, saving millions of lives annually. However, persistent global disparities in blood safety and supply, coupled with the ongoing risks of transfusion-related adverse events and alloimmunization, necessitate continuous innovation. This article provides a comprehensive and unique review of the latest advancements shaping contemporary transfusion medicine, moving the field towards a precision paradigm. We explore cutting-edge developments in global blood safety initiatives, digital transformation using AI and Blockchain, novel blood engineering techniques for universal blood, and the expanding role of therapeutic apheresis and cellular therapies. Specific, up-to-date data from international bodies are integrated to highlight both achievements and critical gaps, particularly between high- and low-income countries, guiding future research and policy.
