A new blood group find in India in 65-year-old man from Gujarat, which is also the rarest in the world. A man with a heart condition has been diagnosed with EMM negative blood group, a rare blood type that cannot be classified into the existing groups of 'A,' 'B,' 'O,' or 'AB.'

In general, there are four types of blood groups in the human body, which further consist of 42 types of systems, like A, B, O, Rh and Duffy. There are also 375 types of antigens in which EMM is high.

Only 10 people in the world have EMM blood group

However, there are only 10 such people in the world who do not have EMM high-frequency antigen in their blood, which makes them different from normal humans. People with such rarest blood groups can neither donate their blood to anyone, nor can they acquire it from anyone.

So far, there were only 9 people in the world with such rarest blood group, but now, a 65-year-old man from Gujarat's Rajkot has been identified with the said blood group.

According to Sanmukh Joshi, a doctor at Surat's Samarpan Blood Donation Center, the 65-year-old patient who was being treated in Ahmedabad after suffering a heart attack needed blood for heart surgery. 

However, the samples were sent to the Surat blood donation centre after his blood type was not found in the Prathama Laboratory in Ahmedabad.

After examination, the sample did not match with any group, following which blood samples of the elderly man along with his relatives' were sent to America for investigation.

Rarest blood is named as EMM negative

Subsequently, it was found that the elderly man's blood type was India's first and world's tenth such case of the rarest blood group. Due to the lack of EMM in the blood, the International Society of Blood Transfusion (ISBT) has named it EMM negative.
