Question

Did you know? There are 4 main blood types — A, B, AB, O — determined by antigens on red blood cells. Karl Landsteiner discovered this in 1900 and received the 1930 Nobel for it. Before that, 50%+ of blood transfusion recipients died because doctors didn't know about the mismatch.

Er zijn 4 hoofd-bloedgroepen — A, B, AB, O — bepaald door antigenen op rode bloedcellen. Karl Landsteiner ontdekte dit in 1900 en kreeg er in 1930 de Nobelprijs voor. Voorheen stierven 50%+ van bloedtransfusie-ontvangers omdat artsen niet wisten over de mismatch.
