In a significant medical breakthrough reported by Rajkotupdates.news:emm-negative-rare-blood-group-found-in-rajkot-man-11th-such-case-worldwide, a 65-year-old man from Rajkot faced a surprising challenge when he couldn’t find a compatible blood match for his cardiac surgery, despite having AB positive blood, known as the universal acceptor. This led to the identification of India’s first recorded case of ‘EMM negative’ blood, which is the 11th such case documented globally. The research paper detailing this discovery, titled ‘Anti Emm, a rare specificity to the high incidence antigen Emm in an Indian patient defining the new blood group system EMM (ISBT042)’, has been published in the prestigious Asian Journal of Transfusion Science.

Ahmedabad: In a remarkable medical discovery, a 65-year-old man from Rajkot encountered an unexpected hurdle when he was unable to find a compatible blood match for his cardiac surgery in 2020. Adding to the surprise was the fact that his blood group was AB positive, universally known as the acceptor group. This prolonged struggle ultimately led to the identification of India’s first recorded ‘EMM negative’ blood case, marking the 11th known instance worldwide.
The findings of the research investigation Anti Emm, a rare specificity to the high incidence antigen Emm in an Indian patient establishing the new blood group system EMM (ISBT042), were published in the prestigious Asian Journal of Transfusion Science. The study was conducted by a team of experts, including Ripal Shah, Snehal Senjaliya, and Sanmukh Joshi, among others. Dr. Ripal Shah, the director of the renowned Prathama Blood Bank in Ahmedabad, offered insights into this extraordinary case.
Dr. Shah revealed that when the patient was unable to find a suitable blood match at blood banks in Rajkot, he sought assistance at Ahmedabad. To their dismay, the outcome remained the same. The patient urgently required blood for a crucial coronary artery bypass grafting surgery. Surprisingly, an antibody within the patient’s blood exhibited reactions both in the saline and antiglobulin phases. Even the blood samples from his own children failed to match his unique blood characteristics, adding to the complexity of the situation.
Blood Samples Were Later Sent To Surat: Rajkotupdates.News:Emm-Negative-Rare-Blood-Group-Found-In-Rajkot-Man-11th-Such-Case-Worldwide
Further investigation into the unique blood case necessitated the transportation of the blood samples to Surat for advanced analysis. Eventually, the samples were sent to a specialized facility in the United States for a comprehensive examination. The subsequent results revealed a striking absence of the EMM phenotype, a characteristic that is typically present in the majority of human red blood cells (RBCs). This absence posed significant challenges in finding a suitable match among the existing blood samples.
Dr. Shah elaborated on the extraordinary nature of the case, stating that the absence of the EMM phenotype occurred naturally in the patient, without any history of transfusion. Among the patient’s relatives, only his brother possessed a similar blood type, although not an exact match. In the event of an emergency, the brother could have potentially provided blood that was compatible with the patient’s unique blood characteristics. However, it is regrettable to report that the patient ultimately succumbed to other health complications before such measures could be pursued.
The utilization of advanced analysis techniques and international collaboration in examining this rare blood case exemplifies the dedication of medical professionals to unravel the intricacies of complex medical conditions. Even while this particular instance could not be resolved, it serves as a reminder of the constant effort to improve our knowledge of the human body and create fresh solutions to deal with unusual medical situations.

Why Do People Have So Many Different Types Of Blood Types?
The complex nature of blood and its various types has been a subject of scientific exploration over time. Today, we have a thorough grasp of this essential fluid and all of its components, including plasma, platelets, white blood cells, and red blood cells. Each element plays a crucial role in maintaining life-sustaining functions within the body.
Of these components, it is the red blood cells that contribute to the diversity of blood types. These cells possess specific proteins, known as antigens, which are present on their surface. The presence or absence of these antigens determines an individual’s blood type. For instance, type A blood solely carries A antigens, type B blood exclusively possesses B antigens, type AB blood contains both A and B antigens, while type O blood lacks these antigens altogether. In addition to these A and B antigens, red blood cells also feature another antigen called the RhD protein. The presence of this protein categorizes a blood type as positive, whereas its absence designates it as negative. Combining the different combinations of A, B, and RhD antigens gives rise to the eight commonly recognized blood types: A positive, A negative, B positive, B negative, AB positive, AB negative, O positive, and O negative.
Understanding the intricacies of blood types has far-reaching implications, particularly in medical contexts such as blood transfusions and organ transplants. Compatibility between the blood types of donors and recipients is crucial to ensure successful outcomes and prevent adverse reactions. The recognition and differentiation of these various blood types allow healthcare professionals to effectively match and administer blood products to patients in need.
Through continuous research and advancements in the field of hematology, our knowledge of blood types continues to evolve. This understanding enhances our ability to provide optimal healthcare and develop new approaches for managing conditions related to blood compatibility.
This groundbreaking case sheds light on the rare phenomenon of ‘EMM negative’ blood, which has previously been documented only ten times worldwide. The research conducted by the esteemed team of experts not only brings attention to this unprecedented discovery but also highlights the pressing need for further investigations into the newly defined blood group system, EMM (ISBT042).
Ans. EMM refers to a specific antigen present in red blood cells.
Ans. eMM negative blood group indicates the absence of the eMM antigen on red blood cells.

Ans. The term “golden blood type” is not recognized in the context of blood groups.
Ans. B negative: 2%
AB positive: 2%
