Rajkot Has Discovered The 11th And First EMM Negative Individuals In The Globe.

Rajkotupdates.News: Emm-Negative-Rare-Blood-Group-Found-In-Rajkot-Man-11th-Such-Case-Worldwide – In Ahmedabad, a 65-year-old Rajkot man was shocked when he discovered that he couldn’t find blood for a 2020 heart procedure that matched his blood group. His known blood type was AB positive, the most common blood type. This added to the surprise. Eventually, after a protracted search, the first blood case in India to test “EMM negative”—the 11th such case worldwide—was found.

Rajkot Has Discovered The 11th And First EMM Negative Individuals In The Globe.

Ripal Shah, Snehal Senjaliya, and Sanmukh Joshi, among others, submitted an article in the Asian Journal of Transfusion Science titled “Anti Emm, a rare specificity to the high incidence antigen Emm in an Indian patient defining the new blood group system EMM (ISBT042).” According to Dr. Ripal Shah, director of the Prathama Blood Bank in Ahmedabad, the patient landed in Ahmedabad with the same outcome after matching blood could not be obtained at Rajkot blood banks. For a coronary artery bypass grafting procedure, he required it. Saline and antiglobulin phases of a blood antibody reaction were occurring. Even his offspring did not share his blood, she claimed.

Later, the blood samples were sent to Surat for sophisticated analysis before being delivered to a laboratory in the US. The outcomes showed that the blood was devoid of the EMM phenotype. It is virtually universally found in human red blood cells (RBC). Therefore, it was challenging to compare it with any available samples due to its absence. It occurred organically because the patient had no prior history of transfusion. Only his brother among his family members has the same blood type, though not precisely, according to Dr. Shah, who also noted that if necessary, his brother might have given him blood. “However, the patient passed away from additional medical issues.”

According to the report, the instance was crucial in establishing Emm as a new blood group system and giving it the designation ISBTO42.


The rarest blood type(EMM Negative), which is said to be only possessed by nine people worldwide, has been discovered in a 65-year-old Rajkot, Gujarat, man. He stated that blood samples from the older man and his family members were transferred to America for testing after analysis showed the models did not belong to any particular group.

Frequently Asked Questions on EMM Negative Rare Blood Group

What is an EMM Negative Blood Group?

According to Rajkotupdates news, the Rajkot guy has the EMM blood type, ranking 10th in the world and first in India. However, the International Society of Blood Transfusion (ISBT) classified the blood as EMM negative since the EMM level was so low. ISBTO42 is the symbol assigned to the blood type.

What was the Doctors’ Reaction?

He had a rare blood group, which startled the doctors, who then recommended Ahmedabad. But again, the medical staff could not locate the life-saving substance that matched his blood type.

How was it Discovered?

It was determined that the patient had an uncommon blood type called EMM negative during treatment. The four main blood group kinds are A, B, O, or AB. In addition, there are 42 other blood system types, including A, B, O, Rh, and Duffy. EMM is also present in high amounts in 375 different types of antigens.

What Was The Result of Lab Testing?

The blood sample taken from his body was tested at a lab, and the results were quite strange and dissimilar from those of the other groups. A lab in New York received the sample to do the tests. The researchers identified the blood group as AB+ with EMM negative frequency after a year-long investigation. Unfortunately, a natural death occurred for the patient earlier this year.

Can people with EMM Negative Blood Group Donate Blood?

Blood donations from people with the EMM-negative blood group are not accepted. This is because they both are unable to get blood from others.

According to experts, even receiving blood from a member of the same group increases the likelihood of a catastrophic inside reaction.
