RH(negative)阴性和RH(positive)阳性是人体血液中最常见的分类方式之一。它们是由一种名叫RH因子的蛋白质决定的。在人的红细胞表面，有些人有这种RH蛋白质，有些人则没有。如果一个人有RH蛋白质，他被认为是RH阳性；如果这个蛋白质不存在于血液中，那么他被认为是RH阴性。这种分类方式是非常重要的，...
any of a group of antigens on the surface of red blood cells, those having inherited such antigens being designated Rh + (Rh positive) and those lacking them, a much smaller group, being designated Rh− (Rh negative):transfused or fetal Rh + blood may induce a severe reaction in an...

What is the difference between O negative and O positive blood? If A blood type produces antibodies for B, then why can AB blood types receive blood from A if the donor blood (A) has antibodies for B? Wouldn't the donor's antibodies for B attack the B antigen in ...

A D-like antigen has been demonstrated in rhesus monkey, human Rh positive and Rh negative red cells. These, as well as heat extracts of human Rh positive or Rh negative red cells, induce formation of D-like antibodies in guinea pigs. The latter antibody seems to act on a site on the...
I have type O Rh negative blood. I am rarely I’ll and I work as a preschool teacher. I was even asymptomatic when I tested positive for COVID-19. My second pregnancy was considered high risk. T paul says: Thank you for asking because I was gonna ask… I hope you got an answer...
Humans have four main blood groups, type A, type B, type AB, and type o. Humans can also have "positive" or "negative" blood. People with type o negative are considered universal donors because they lack surface antigens that could cause an immune reaction in the receiving patient. ...
even if the father is Rh negative. Rh blood typing and testing currently are performed routinely atthe first visit. If the mother is Rh positive, there is no cause for concern. If, however, the mother is Rh negative, the father should be checked. If he also is Rh negative, there is ...
In a previous report (Finn et al ., 1961) we gave reasons for thinking that the rapid removal of Rh-positive foetal erythrocytes from the circulation of a mother who was Rh-negative would prevent her from becoming immunized and producing Rh antibodies. We have now investigated the matter furt...
