During the next operation, during a blood transfusion, my body did not accept someone else's blood, the dropper hung. After some time I was again put on an IV, after a while my body became covered with large red spots, and my body shook as if from an electric shock. The dropper was turned off. The next day, a plasma dropper was placed, 300 ml was injected for more than 2 hours. They didn't explain anything to me. What I didn't know
50 years my blood is of the first group with a plus, but when I changed my driver's license
for some reason I became the first group with a minus Here is a riddle
Maybe the error or maybe really changed Not I know
I changed from + to -. After two hemodialysis operations and infusion of 7 liters of blood and plasma into me. Prior to that, he underwent four operations and had 1+ blood. After two operations and 1-.
Both are genetically encoded traits. It is only theoretically possible to imagine that a mutation in a bone marrow cell that produces red blood cells will cause it to produce red blood cells that cannot be attributed to a person's blood group - but all other cells will produce normal red blood cells, and the likelihood of such a mutation is extremely small. Rather, in order to talk about a different blood type, many mutations are needed, the cell will die much earlier than it accumulates.
Personally, I was born with 2-, and I don't know why at 40 I have 2+. The most interesting one. Errors are excluded, since has been checked repeatedly. The doctors themselves are surprised. There were no blood transfusions.
