- Percentage Of People Who Have It: Less Than 0.5% (Only 43 People Have Ever Reported To Have It)
We should state that we do not literally mean blood made of gold or gold-colored blood. Rather, this name typically comes from the rarity of this blood type. It is so rare that most hospitals have only a small supply of it or none at all. The “golden blood” is officially called the RH Null blood type. Basically, those with this blood type are missing all of their RH-blood antigens. Interestingly, anyone with another rare RH blood type can accept this blood type from donors.
As you can assume, since RH blood types are rare themselves, having RH Null blood around to give to ANY within the RH group is massively valuable. That is why those with this blood type are asked to donate as much blood as they can, as the medical community needs it in hospitals. However, due to the need hospitals have for it, RH Null blood is heavily needed for those who study blood too. If RH Null people did not exist, it could take literally months to years to find a specific RH donor.
