Blodgrupp a negativ
There are four major blood groups determined by the presence or absence of two antigens, A and B, on the surface of red blood cells. In addition to the A and B antigens, there is a protein called the Rh factor, which can be either present (+) or absent (–), creating the 8 most common blood types (A+, A-, B+, B-, O+, O-, AB+, AB-).Födelsebevis blodgrupp In April , an international team of researchers announced in the journal Nature Biotechnology an inexpensive and efficient way to convert types A, B, and AB blood into type O. This is done by using glycosidase enzymes from specific bacteria to strip the blood group antigens from red blood cells.
Blodgrupp o Blodgrupp A har antikroppar i blodet som angriper B-blodkroppar, blodgrupp B har antikroppar mot A-blodkroppar. Blodgrupp AB saknar antikroppar mot A-blodkroppar och B-blodkroppar medan blodgrupp 0 har antikroppar mot både A-blodkroppar och B-blodkroppar.
