We will soon be able to make all blood groups compatible



If successful, here is a scientific research that promises to be a revolution. An American team has developed a method to make a universal group of every blood group. That is type O-. Which fight against the recurring blood shortages belonging to this group. And it is in our digestive tract that is the key to the mystery.

It is an enzyme of the intestine. His role is to eliminate sugars that are present in the lining of the digestive tract. These sugars are similar to those in blood cells. Groups A, AB and B, while group O is deprived of these sugars. The principle is that in contact with the blood of the 3 groups in question, the enzyme absorbs the sugars and the groups A, AB and B change into O …

"It's nothing scary"

Stephen Withers, a professor at the University of British Columbia, is reassuring, but acknowledges that the information seems extraordinary to the population. "People are surprised. It sounds strange in their heads. They think that we change the blood type of a person, which seems scary. In reality, we simply transform the blood after it has been taken from this person"

The dream of blood banks

More blood from group O is the dream of blood banks. Because blood from group O can be given to everyone, says Stéphane Eeckhoudt, director of the blood bank of the Saint-Luc Clinic. "Nowadays, the need for blood groups means that there must be a supply of 250 to 300 sachets with different blood groups. O blood is precious blood. This is the first blood that is administered during an emergency, for example for a traffic accident. If you have to undergo an emergency transfusion, you are giving this O-blood, so in the future this will considerably facilitate our stock management and the search for donors."

If Canadian researchers still have to perform clinical trials to validate their research, they want to convert human blood on a large scale in the next five years.
