Bheng here, good evening to all, i will share about blood types n the rarest blood types too, hope u will take time to read it :) Blood has 2 main groups namely ABO and RH. ABO blood system has 4 types Type A- has a A marker known as A. Type B- has a B marker known as B. Type AB- has both A & B markers Type O- has neither A or B markers. Blood futher classified as being either " RH Positive(RH+) " has RH factor or " RH Negative(RH-) " without RH factor. 8 possible Blood types O Negative(O-) doesn't have A or B markers & it doesn't have RH factor. O Positive(O+) doesn't have A or B markers but does have RH factor. One of the 2 most common blood types(the other being A Positive(A+). A Negative(A-) has A marker only. A Positive(A+) has A marker & RH factor, but not B marker. Along with O Positive(O+) one of the 2 most common blood types. B Negative(B-) has B marker only.
