Question

Why is Rh Negative blood called Royal Blood?

Answer 1

Never heard that one.

Answer 2

never heard that one before-- Rh A-, just know that even my type is comprised of only about 15% of world population--knew hemophiliac was attributed to royalty--thanks have to look that one up

Answer 3

I found this from the times article: The regal donor of the precious stuff was Prince Charles, 36, who has become the first member of the royal family ever to give blood, in his case, O Rh-negative. The unprecedented puncturing of royalty was to reassure Britons after a nationwide scare about AIDS caused a drop in donations. At the North London Transfusion Center, the Prince was asked whether he was homosexual, injected drugs into his veins or had had s*x with anyone in those two groups. After those regulation indignities (and his negative answers), he had an apprehensive question of his own: "Is it going to hurt?" When the pint was finally drawn, Charles pretended to apologize because his blood was not blue: "I'm afraid it's red like anyone else's."

Answer 4

Rh O-Neg is used as it is a universal donor type. It is usually broken down and seperated into plasma, platelets etc. This type was found in many Royals and was passed to their heirs. So many of the relatives were also negative. It 's not found in many people in the population. Only a small percentage.

Answer 5

Because it is a rare blood type and they have found  some royalty to have that blood type.
