The historical milestone in transfusion medicine was achieved in the Rotary Bangalore TTK Blood Center, where a new blood type, formerly unidentified anywhere in the world, was discovered in a 38 -year -old South Indian woman.
The International Blood Group (IBGRL) reference laboratory in Bristol in the UK, which after 10 months of extensive research and molecular testing detected the unknown antigen of the blood group. As a recognition of its origin, the group was officially named “Crib”, with CR presenting Cromera and IB standing for India, Bengaluru.
When a 38 -year -old woman was admitted to the RL Hospital Hospital and Research Center in Kola for Heart Surgery in February last year, she knew little to do history. Her blood type was positive. Surgeons asked a hospital blood bank to maintain compatible blood before surgery. However, they could not find a single matching unit from their positive blood supply.
Ankit Mathur, another Medical Director in Rotary Bangalore TTK Blood Center, said Hindu on Tuesday that her blood sample was sent from Jalappa to the advanced immunohematology reference laboratory in the Rotary Bangalore TTK. This means that it was incompatible (uncomfortable) with all the samples they tested using advanced techniques.
Family -tested
“This case was very complicated and it was a strong hint of rare blood group. Because rare blood types sometimes occur as clusters in the family, we gathered blood samples from 20 family members, including her children.
“In the future, if a woman needs blood transfusion, we may have to make an autologous transfusion. If it is a planned surgery, we may have to give it iron supplements to increase hemoglobin levels and collect its own blood and use it if necessary for surgery,” he explained.
Subsequently, the patient’s blood and families were sent to the International Reference Laboratory of Blood Groups (IBGRL), Bristol, the United Kingdom “After about 10 months of advanced Ibggl testing, she said she has a new antigen in antigen. the center.
At the 35th Regional Congress of the International Society for Blood Transfusion (ISBT), which took place in Milan in Italy, June 4, 2025, this antigen was appointed Crib. “As a result, a woman is the first person in the world to represent this antigen. The blood group nomenclature decides ISBT, red cell immunogenetics and terminology,” Dr. Banerjee.
A register of rare donors
To support blood requirements in patients with rare blood groups, Rotary Bangalore TTK Blood Center’s Bangalore Medical Services Trust (BMST), in conjunction with the Karnataka State Blood Transfusion Council and ICMR’s National Institute of Immunohematology, launched a “rare blood donor” in January last year.
“In recent years, we have been helpful in identifying and providing optimal transfusion support for several other rare patients with blood type (such as D- – RH Null and negative). These cases have also been published and introduced on international forums.
