How prevalent is RhD positivity among non-Hispanic white men?

RhD positivity, which refers to the presence of the RhD antigen on the surface of red blood cells, is a significant genetic marker in blood types. In non-Hispanic white individuals, the prevalence of RhD positivity is indeed highest among the options presented, aligning closely with the statistics observed in the general population of this demographic.

Research indicates that approximately 85% of non-Hispanic white men are RhD positive, which explains why this answer is supported by empirical data on blood types. This high prevalence is attributed to genetic factors and the historical populations from which these groups descend. It’s essential to understand this context as it underlines the importance of Rh factor in various medical settings, particularly in obstetrics where maternal-fetal incompatibilities may arise if the mother is RhD negative and the fetus is RhD positive. Understanding these statistics can help inform clinical practices and patient management in maternity care.
