Normally it’s believed that the rare blood group is O- (negative), which is extremely difficult to get because it’s found only in selected people. But instead of O- (negative) there’s a rarest blood type that’s found in one from millions of people, and its name is Bombay Blood Group Type . This blood type is additionally called Rare of the Rarest blood type . To donate blood to the needy and save their life is that the work of virtue. before donating blood, the doctor examines the blood type and ensures that the person can donate blood or not. Normally, blood type is of 4 types – A, B, AB & O. it’s compulsory to match blood type before donating blood, otherwise it are often dangerous or maybe increase the health problems. In this article, we’ll study about the rarest blood group type “Bombay Blood Group”.
What is the Bombay Blood Group?
This type of rarest blood group is found only in the world of 0.0004% of the population. Just one person in 10,000 people in India has Bombay Blood Group . it’s also called HH blood type or Rare ABO blood group. This blood phenotype was first discovered by the Doctor YM Bhende in 1952.
This is called Bombay Blood because it had been first found in some people of Bombay. The HH blood type contains one antigen, the H antigen, which is found on virtually all RBCs and is that the building block for production of antigens within the ABO blood type . To know more, their red blood cells (RBC) have ABH antigens and their sera contains antigen-A, antigen-B, & antigen-H.
Anti-H has not been discovered in ABO blood group, but it’s been detected in Pre transfusion Test. This H antigen works as a building block in ABO blood type . The shortage of H antigen is understood as “Bombay phenotype“.

A person with a Bombay blood type can give blood to an ABO blood type person. But they can’t receive blood from them. An individual can take blood only from its own blood group ie HH blood group .

Let’s see about blood grouping.
In the year 1900-1902, K. Landsteiner divided the human blood into 4 groups- A, B, AB & O. Except the O blood type , A, B, AB groups have corresponding antigens. Therefore, O can give blood to any blood type then it is named as universal blood donor . AB group is named Universal Recipient because it can take blood from A, B, AB and O i.e. from all blood groups.
