In 2020, a 65-year-old resident of Rajkot was taken aback when he failed to find compatible blood for his heart surgery despite having a known blood type of AB-positive, which is considered a universal acceptor. After an extensive search, he stumbled upon a rare case of EMM-negative blood, which happens to be the 11th documented incidence of its kind worldwide and the first of its kind in India.
The Emm-negative blood group is a subtype of the Bombay blood group, which has an occurrence rate of 1 in 250,000 individuals in India. The Emm-negative subtype is rarer, with only a few cases reported globally. This rare blood group lacks a specific antigen on the surface of red blood cells, which makes it challenging to identify the A, B, AB, or O blood groups. It means only compatible blood from individuals with the same rare blood type can be used for transfusion.
The discovery of this rare blood group in Rajkot has highlighted the need for more awareness of rare blood groups and an adequate blood bank supply that can cater to such cases. It is essential to have a sufficient supply of blood to meet the needs of patients with rare blood groups in emergency situations. Regular blood donation can help maintain an adequate blood bank supply and save lives.
The Rajkot Blood Bank Society plays a vital role in identifying individuals with rare blood groups and providing the necessary support to patients. Their efforts have led to the discovery of the Emm-negative blood group in a 65-year-old man in Rajkot. It is crucial to have non-profit organizations like the Rajkot Blood Bank Society that operates blood banks in the city and regularly conducts blood donation drives and blood group testing camps.

About the EMM-negative Rare Blood Group
The Emm-negative rare blood group is a very rare subtype of the Bombay blood group, also known as the hh blood group. Individuals with this blood group lack a specific antigen on the surface of their red blood cells, which makes it impossible to classify their blood as A, B, AB, or O. Only a few cases of this rare blood group have been reported worldwide, making it difficult to find compatible blood for transfusions in emergency situations. It is important to increase awareness of rare blood groups like the Emm-negative subtype and maintain an adequate blood bank supply to cater to the needs of patients with rare blood groups.
Why EMM-negative people can’t donate
Since EMM-negative blood is extremely rare, it is not possible for most blood banks to have this blood type readily available. Therefore, individuals with this blood type are encouraged to donate blood only to blood banks that can process and store their blood type for their own use or for others with the same blood type. This means that EMM-negative individuals cannot donate blood to regular blood banks, as the blood may not be compatible with other blood types, potentially causing harm to the recipients.
However, EMM-negative individuals can still play a crucial role in helping those with rare blood types by donating blood to blood banks that specialize in storing rare blood types or by participating in research studies aimed at finding compatible blood types for individuals with rare blood groups.
Types of Blood Group?
There are several different types of blood groups, but the most commonly recognized system is the ABO blood group system, which classifies blood into four main groups: A, B, AB, and O.
- Blood type A: individuals with this blood type have red blood cells with A antigens on their surface and produce antibodies against B antigens.
- Blood type B: individuals with this blood type have red blood cells with B antigens on their surface and produce antibodies against A antigens.
- Blood type AB: individuals with this blood type have red blood cells with both A and B antigens on their surface and do not produce antibodies against either A or B antigens.
- Blood type O: individuals with this blood type have red blood cells without A or B antigens on their surface and produce antibodies against both A and B antigens.
- Rh system: Apart from the ABO system, there is also the Rh system, which categorizes blood as either Rh-positive or Rh-negative, depending on the presence or absence of the Rh antigen on red blood cells.
- In addition to the ABO and Rh systems, there are numerous other less-common blood group systems that are important for transfusion medicine and transplantation. These systems include the Kell, Duffy, Kidd, and MNS systems, among others. Understanding an individual’s blood type is critical for blood transfusions and organ transplantation, as incompatible blood types can cause severe and sometimes fatal immune reactions.
