每一个人对自己的血型都充满着好奇。你知道自己的血型吗?有人以为血型很神秘,有人认为血型很复杂,也有人认为血型很简单。下面让我们来认识自己的血型。 血型发现至今不过一百多年。1900年,奥地利人Landsteiner将不同同事的血清和红细胞相互混合在一起,发现有些凝集,有些无凝集,从中得到启发,认识到红细胞上有一种特异性抗原,从而发现了人类ABO血型系统。1921年世界卫生组织把ABO血型系统的血型正式向全世界统一命名为A、B、O、AB四种血型。在以后的数十年里,又相继发现了其他血型,到1995年,共发现了23个红细胞血型
Everyone is curious about his own blood type. Do you know your blood type? Some people think that the blood type is very mysterious, some people think the blood type is very complicated, some people think the blood type is very simple.

In 1921, the World Health Organization (WHO) officially unite the blood type of ABO blood group system to the world as A, B, O and AB. In the next few decades, have found other blood types, by 1995, a total of 23 red blood cells were found
