EMM Negative Rare Blood Group Found in Rajkot Man 11th Such Case Worldwide

EMM Negative Rare Blood Group Found in Rajkot Man 11th Such Case Worldwide – A 65-year-old Rajkot resident was surprised when he couldn’t locate blood that matched his blood type for a 2020 heart surgery. His blood type was AB-positive, which is a proven universal acceptor. A Rajkot, India citizen is find to have an uncommon and negative blood group in a revolutionary EMM-negative blood case published by Rajkot Updates News.

This is the 11th known case of this blood group globally, underlining its remarkable rarity. The story has sparked widespread interest in the medical world, shedding light on the specific issues connected with this blood type. In this article, we will look at the specifics of this remarkable discovery and analyze its consequences for blood grouping.

What is an EMM Negative Blood Group?

Four blood groups in the human body consist of 42 types of systems, like A, B, O, Rh, and Duffy. Moreover, there are 375 types of antigens in which EMM is high.

The International Society of Blood Transfusion (ISBT) has called it EMM negative. Due to the absence of EMM in the blood, People with these rarest blood groups can neither donate nor receive. Which makes them different from normal humans.

Introduction of EMM Negative Rare Blood Group

The presence or absenteeism of antigens on the outmost layer of red blood cells (RBCs) determines a blood group. More than 300 blood-type antigens recognize; however, the ABO and Rh systems are the most well-known. The Emm antigen, a part of the Dombrock blood group system (DO), is absent in the Emm negative blood group, an uncommon blood type. The ART4 gene encodes the Emm antigen; in transfusion circumstances, its absence can result in immunological responses.


A 32-year-old lady who had severe anemia arrived at the hospital. Blood samples were taken to do a complete blood count (CBC), blood type, and antibody screening in a laboratory. Further investigations use molecular and serological techniques to confirm the Emm-negative blood group.


The patient’s blood type was found to be AB RhD-positive. Initial serological tests for blood group antigens showed a weak reaction with anti-Emm. Molecular testing confirmed the absence of the Emm antigen, which was caused by a homozygous mutation in the ART4 gene. After a thorough search, only ten other examples of the Emm-negative blood group were found in the literature, making this the eleventh case to be reported globally.

How a Rajkot Man Was Diagnosed with the Rare Blood Group EMM-Negative

Recently, a man from Rajkot diagnoses with the rare blood group EMM-Negative, making him the 11th such case worldwide. This incredible discovery has been made possible due to advancements in medical technology. And also Diagnosing this rare blood group helps us understand more about our biology and how our bodies work. It also highlights the importance of access to proper medical facilities to diagnose and treat rare diseases like this. With this detection, we can provide well care and treatment to patients suffering from this ailment.

In a unique medical instance, a Rajkot man diagnoses with the unusual blood group EMM-Negative. This is only the 11th example globally and only the second in India. Modern technology and effective medical care at Rajkot’s city hospital enabled the diagnosis.

Before being diagnosed with this unusual blood group, the individual had suffered from severe anemia and other symptoms for quite some time. His instance underlines the need to analyze and treat uncommon medical diseases correctly. It demonstrates how technology can quickly identify such occurrences and deliver prompt care to those in need.

What Are The Effects Of Having A Rare Blood Group?

Having a rare blood group can be both a blessing and a curse. In this case, it is helpful because it allows the specific to donate blood to needy people. But on the other hand, finding well-matched donors can be difficult.

Recently, a man in Rajkot is find to have a rare blood group – EMM negative – making him the 11th such case worldwide. This case has highlighted the importance of understanding what having a rare blood group entails and how it affects individuals. In this article, Will will discuss the effects of having a rare blood group and what precautionary measures should be taken by those diagnosed with one.

EMM Negative People Can’t Donate

EMM Negative People Can't Donate

Blood donations from people with the EMM negative blood group are not accepted. They are unable to accept anyone’s blood. Professionals say that if a person even receives blood from someone from the same group, the chances of reaction inside the body multiply and could prove fatal.

Implications for Blood Transfusion Matching and Medical Science

The blood type EMM-negative’s rareness highlights the importance of knowing the variety of blood types and the consequences of matching blood transfusions. The accuracy of identification of the blood type and matching is crucial in ensuring the security and efficiency of blood transfusions and finding extremely rare.

Rarity And Challenges Of Negative Rare Blood Groups

Negative rare blood types are extremely rare, with only a handful of documented examples worldwide. The lack of A and B antigens reduces the supply of compatible blood for transfusions, making it difficult to find acceptable donors. Individuals with negative uncommon blood types frequently require large donor databases and sophisticated screening techniques to find appropriate matches. The scarcity of proper blood donors creates substantial hurdles in supplying these people with timely transfusions.

Understanding Blood Groups and Their Significance

Understanding Blood Groups and Their Significance

Medical treatments, transfusions, and organ transplants all rely on blood types. The ABO system divides blood into four categories: A, B, AB, and O, with the presence or absence of the Rh component determining whether the blood is positive or negative. This system of classification aids in determining compatibility for blood transfusions and organ donations.

Doctor Sanmukh Joshi’s Words

Sanmukh Joshi, the doctor at Samarpan Blood Donation Centre, Surat, said the 65-year-old man was undergoing treatment after a heart attack. He needed blood for heart surgery. Moreover, his blood group did not match with others in the laboratory. Hence, his blood samples were sent to the Surat blood donation center for further examination.

Significantly, the blood group did not match with any of the existing groups. For detailed analysis and investigation, the sample sends to America. There it observes that the person does not have EMM high-frequency antigen in his blood.

Future Prospects and Medical Advancements
