The present retrospective epidemiological study collected data on a sample of 710 newborns and compared the incidence of neonatal jaundice in infants born to Rh (D) negative and 0 Rh (D) positive mothers. The primary aim was to determine whether the higher incidenc...
No, because to be rh negative, one must have TWO rh negative alleles. The rh factor is recessive. If both parents are rh negative, they must have ONLY rh negative alleles. Therefore they do not have any positive alleles to pass on to their children. Can your blood type change? Usually,...
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...
目前,人类已经发现了44个血型系统,Rh血型系统是除ABO系统以外最重要的血型系统,其中D抗原免疫原性最强。抗-D同种免疫可引起严重的溶血性输血反应或胎儿和新生儿溶血病(hemolytic disease of the fetus andnewborn,HDFN),具有重要的临...

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 ...
抗-D抗体产生人群Rh分型与输血安全探讨
A "D"-like antigen has been demonstrated in human and rhesus red cells. These red cells, as well as heat extracts of human blood (Rh-positive or Rh-negative), induce formation of "D"-like antibodies in guinea pigs. These antibodies, when exposed to rhesus red cells or to Rh-positive ...
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 ...
