New CRIB Blood Group Discovered in Bengaluru Woman
Imagine blood like a special key.
Scientists have found a new and unique key, called CRIB.
A woman in India has this new key in her blood, which is so rare it's never been seen before.
Her blood didn't match any other blood types.
This means if she needs blood, it's very tricky to find a match.
Scientists are now learning more about this new key to help doctors understand blood better and give the right blood when needed.
A woman from Bengaluru, India, has been found to have a new and extremely rare blood group antigen called CRIB.
CRIB belongs to the Indian Rare Antigen (INRA) blood group system, recognized in 2022.
The discovery was made after the woman's blood was found incompatible with all available blood types.
CRIB is characterized by the absence of a common antigen, making transfusions complex.
Scientists are developing screening tests and raising awareness to identify carriers.
