what’s rare blood type
As for now, all in the world considered Bombay blood group is the rarest one. If you think soo even now it is wrong. You may think if Bombay Blood group is not then what?
Hold on that curiosity till end.
Before we get it to it we have to know how to find out the blood type of one’s. It is defined by which antigen is present in the blood.
There are two antigens “A” and “B”. If the blood contains “A” antigen then it is said to be “A” type. If it contains “B” antigen then it is “B” type.
If it contains both “A” and “B” then it is “AB” type, If there is neither “A” nor “B” present then it is “O”.And the final “-ve” and “+ve” are determined by the “Rh” protein. If “Rh” protein is present then it is positive if not it is negative.
Now you got the idea of how to classify the things. The “Rh” factor is determined for “+ve” and “-ve”, in the researches the scientists found that there is a type having no “Rh” factor.
Which is now the rarest blood group. It is known as Rh null blood group or Golden blood group. Only a few members are having this blood group. Only 43 out of the world are reported having this one. It lacks 61 antigens if it is Rh null group.
It is considered as the most dangerous one also. The one with having this type should have been treated with the same kind which is a lot difficult.
As for now in the United States, the common blood group is O +ve, one in three are this type. And the rarest is AB -ve which is also known as Bombay blood group. From now the Golden Blood group joined this list of rarest one.
