What is RH blood group?
RH is the first two letters of mbth, a macaque. Randsteiner and other scientists found that rhesus monkeys and most human red blood cells have antigen substances of RH blood group when doing animal experiments in 1940, hence the name. Anyone with RH antigen (also known as D antigen) on red blood cells is called RH negative. In this way, people who have found four main blood types of red blood cells, A, B, O and AB, are divided into RH positive and RH negative respectively.
In China, RH-negative blood group only accounts for three to four thousandths. The ratio of RH negative type A, type B, type O and type AB is 3: 3: 3: 1.
What are the possible dangers of people with RH negative blood type?
RH-negative people can't accept the blood of RH-positive people, because the antigen in RH-positive blood will stimulate RH-negative people to produce RH antibodies. If RH positive blood is transfused again, it will lead to hemolytic transfusion reaction. However, RH-positive people can receive blood from RH-negative people.
