The New Human Blood Type That Only 3 People on Earth Have-and the Hunt for the 4th

Key Points:
- Researchers have identified a new rare blood type called B(A), discovered during blood studies at a Thai hospital, bringing the total known human blood types to 49.
- The B(A) blood type features mostly B antigens with trace amounts of A antigens and is caused by four specific gene mutations unique from previously known alleles.
- This blood type was found in only three individuals—one patient and two donors—and highlights the complexity and variability of blood typing beyond the traditional ABO system.
- The discovery suggests there may be additional rare blood types yet to be identified, emphasizing the need for ongoing research in blood antigen diversity.
- Understanding these rare blood types is crucial for safe blood transfusions, as antigen compatibility prevents immune rejection during transfusions.
