Rotary Bangalore TTK Blood Centre Discovers Unique New Blood Group

swift Summary

• A new blood group, termed ‘CRIB’, has been discovered in a 38-year-old South Indian woman by the Rotary Bangalore TTK Blood Center.
• The International Blood Group Reference Laboratory (IBGRL) in Bristol, U.K., identified this blood group as part of the Cromer (CR) system after 10 months of advanced research and molecular testing.
• The name ‘CRIB’ reflects its origin: CR stands for Cromer, and IB represents india, Bengaluru.
• The finding occurred when the patient underwent cardiac surgery at R.L. Jalappa Hospital in Kolar. Her O Positive blood was found incompatible with all tested samples.
• Family members were also tested as rare blood types sometimes cluster within families; however, none were matches.
• Researchers concluded it is a never-before-seen antigen associated with the Cromer system during investigations at international laboratories.
• At an international conference in Milan on June 4, 2025, ISBT officially named and recognized this antigen as CRIB.
• Rotary Bangalore TTK Blood Centre supports patients with rare blood groups through its Rare Blood Donor program launched last year.

Indian Opinion Analysis

This landmark discovery places India firmly on the global map of transfusion medicine research by unveiling an unknown blood group antigen ‘CRIB,’ named to reflect local origins-India and Bengaluru.It emphasizes India’s growing capabilities in medical science collaboration globally while solving complex healthcare challenges locally.

The implications are twofold: first, it highlights the critical need for robust rare donor registries to ensure transfusion support becomes accessible for individuals facing similar compatibility issues; second, it reinforces continued investment into complex immunohematology practices that can elevate diagnostic precision nationwide.

such advancements not onyl offer life-saving solutions but can pave pathways toward more inclusive healthcare systems capable of addressing genetic rarities across populations.
