The Rh-null blood type is the rarest type of blood in the world. Researchers estimate that only 1 in 6 million people are born with it, and reportedly, fewer than 50 people are generally known to have had it.
The rarest blood type in existence is Rhnull blood. This stuff is characterized by a complete lack of antigens in the Rh system, which is the largest blood group system. This includes the D antigen (Rh factor, baby), plus the other 50-something antigens in the group.
There are four main blood types. Blood type A is the oldest, and existed even before the human race evolved from our ancestors.
Of the eight main blood types, people with Type O have the lowest risk for heart attacks and blood clots in the legs and lungs. This may be because people with other blood types have higher levels of certain clotting factors, which are proteins that cause blood to coagulate (solidify).
O negative blood can be used in transfusions for any blood type. Type O is routinely in short supply and in high demand by hospitals – both because it is the most common blood type and because type O negative blood is the universal blood type needed for emergency transfusions and for immune deficient infants.
The new blood group is called Er or erantigens. There are five blood types in this group based on genetic variations of what's known as the Piezo1 protein, which is found on the surfaces of red blood cells.
Royal blood, or royal descent, indicates lineal descent from a monarch.
Rh-null blood can be accepted by anyone with a rare blood type in the Rh system. “Golden blood” is as rare in reality as it was in ancient Greek mythology: only forty-three people in the world are known to have had this blood type.
The Viking invaders may have also had a relatively high percentage of B gene, since many of the towns of Britain and western Europe that are linked to the coast by internal lines of communication such as large rivers, have a disproportional amount of blood group B when compared to the surrounding territory.
Chances are higher you'll live longer if you have type O blood. Experts think your lowered risk of disease in your heart and blood vessels (cardiovascular disease) may be one reason for this.
At least two of the extinct, ancient humans had type O blood, making them the “universal donor”, according to a new genetic analysis of remains of 45,000 year old individuals.
Recent work has demonstrated an association between ABO blood types and COVID-19 risk. Using data from Wuhan and Shenzhen, Zhao et al. found a greater proportion of A and a lower proportion of O blood types among COVID-19 patients, relative to the general populations of Wuhan and Shenzhen [4].

O- donors have the “magical” blood — the one that can be transfused to all patients in need, regardless of their blood type!
Type O people have been linked to characteristics such as confidence, determination, resilience, and intuition, but they are also supposedly self-centered and unstable. They are said to especially appear selfish to individuals with Type A blood.
The term “blue blood” has been used since 1811 to describe royal families and the nobility.
Why is royal families said to have blue blood.
A blue blood is an aristocrat. Blue bloods come from privileged, noble families that are wealthy and powerful. The word blood has long referred to family ties: people you are related to share the same blood. One specific type of family is composed of blue bloods: members of the aristocracy.
The Rh-negative blood type can pose risks during pregnancy, including increasing the risk of miscarriage or stillbirth in the second or third trimester.
Usually, you'll have the same blood type all of your life. In rare cases, however, blood types can change. The change usually relates to unique circumstances, such as having a bone marrow transplant or getting certain types of leukemia or infections. Not all of these changes in blood type are permanent.
O− blood, also called "universal donor," is perhaps the most valuable blood in the world because it can be transfused to nearly any blood type (except when the person has some rare antigen outside of the main ones).
As friends, people with type A are considered very reliable and trustworthy. If you are in trouble, you can rely on friends with this blood type. They may not like to show their emotions; they keep their thoughts or feelings about things hidden from others, and they only show vulnerability when comfortable.
Blood Group (O): the holders of this blood type are having in their lives physical and personal strength, stamina, self-reliance, courage, pursuit of success, leadership features, power, and optimism.
