What Is the Most Rare Blood Type?

Rare blood type is a rare or rare blood type. This blood group exists not only in the ABO blood group system, but also in some rare blood group systems. With the deep research of blood group serology, scientists have established the rare blood group systems that have been found, such as RH, MNSSU, P, KELL, KIDD, LUTHERAN, DEIGO, LEWIS, DUFFY, and other rare Blood type system.

Rare blood type is a rare or rare blood type. With the deep research of blood group serology, scientists have established the rare blood group systems, such as RH, KIDD, MNSSU, P, DEIGO, LEWIS, KELLLUTHERAN, DUFFY, and a series of other rare blood group systems . Landsteiner and other scientists did animal experiments in 1940 and found that RH blood group antigens were present on red blood cells in rhesus monkeys and most humans, so they were named RH blood types. Anyone who has RH antigen (also known as D antigen) on human red blood cells is called RH positive, otherwise it is RH negative ^[1]

RH is the first two letters of the foreign name of Rhesus Macacus.

Rh blood group test is clinically important, second only to the ABO system. Because transfusion of Rh blood group incompatibility may endanger the patient's life; pregnancy of Rh blood group incompatibility between mother and child may occur

The demand for rare blood types has risen to a clinical need, and any of us may encounter this at any time. There are many different types of rare blood types, but their common feature is that they are difficult to find. It is important for everyone to know if they are a rare blood type. Some patients with rare blood types must infuse them with exactly the same rare blood group, so we need to save all types of blood of rare blood types, and the rare blood group bank is born from this.

In 1985, the International Blood Transfusion Association set up a rare blood group committee to coordinate and promote the screening, packaging, transportation, and international cooperation of rare blood types. There are four large rare blood group banks in the world, which are located in the United Kingdom, the United States, the Netherlands, and Japan. The largest of these is the International Rare Blood Bank in the UK. The library already contains archives of more than 4,000 blood donors of rare blood types from many countries.

In China, the Ministry of Health requires some provincial blood centers in China to start rare blood group screening projects among blood donors from 2009, and to save all types of blood of rare blood types and information of blood donors of rare blood types.

The Shanghai Blood Center took the lead in developing screening for Rh-negative blood, which is very rare in the Chinese population. Over the past ten years, nearly 10,000 Rh-negative blood donors have saved countless patients' lives through their dedication. Beginning in 2003, with the help of the International Blood Transfusion Association, the Shanghai Blood Center has carried out the screening of a variety of rare blood types among its blood donors. It hopes that enough rare blood type blood donors will be obtained through screening and that they can always keep in touch with them. Provide clinically needed rescue blood as quickly as possible. More and more rare blood types are gradually discovered, and China's own rare blood type bank is gradually growing ^[1] .
