RE: Blood type
Thanks such much for reading
Yes with the O group there is the Rhesus factor
Since the O group lack the antigens on it’s surface the anti Rh serum D which is used for Rhesus is also use to determine the O group which makes it Rhesus positive or negative in case of agglutination or not respectively
The O group as a whole is the universal group both positive and negative the only advantage with O negative is that it can be used as a first line of emergency without screening.
Thanks again for reading you question just made me wanna write more
