Group O can donate red blood cells to anybody. It's the universal donor. Group AB can donate to other AB's but can receive from all others. Group B can donate red blood cells to B's and AB's.

Types O-negative (O-) and O-positive (O+) are best suited to donate red blood cells. O-negative is the universal blood type, meaning that anyone can receive your blood. And O- and O+ blood are both extra special when it comes to traumas where there is no time for blood typing.
Blood is considered Rh-null if it lacks all of the 61 possible antigens in the Rh system. This not only makes it rare, but this also means it can be accepted by anyone with a rare blood type within the Rh system. This is why it is considered “golden blood.” It is worth its weight in gold.
What's the rarest blood type? AB negative is the rarest of the eight main blood types - just 1% of our donors have it.
blood royal in American English
noun. all persons related by birth to a hereditary monarch, taken collectively; the royal kin.
One of the world's rarest blood types is one named Rh-null. This blood type is distinct from Rh negative since it has none of the Rh antigens at all. There are less than 50 people who have this blood type. It is sometimes called “golden blood.”
However, the need for O negative blood is the highest because it is used most often during emergencies. The need for O+ is high because it is the most frequently occurring blood type (37% of the population). The universal red cell donor has Type O negative blood. The universal plasma donor has Type AB blood.
Rhnull or “golden blood”
Rhnull is a rare blood type that doesn't contain any Rh-antigens in red blood cells.
The oldest of the blood types, Type O traces as far back as the human race itself. With primal origins based in the survival and expansion of humans and their ascent to the top of the food chain, it's no wonder Blood Type O genetic traits include exceptional strength, a lean physique and a productive mind.
Currently, no scientific evidence supports a cause-and-effect relationship between a person's blood type and personality traits. Even using current investigative methods, a 2021 study examining blood type and personality demonstrated no significant correlation.
For example, if someone's Rh factors are both positive, it is not possible for his or her child to have a negative blood type. Only people with at least one Rh-negative factors will have a negative blood type, which is why the occurrence of Rh-negative blood is less common than Rh-positive blood.
The new group is called the Er blood group. According to a study in the journal “Blood,” there are now a total of five Er antigens in this group based on genetic variations. The blood type can cause immune cells to attack mismatched cells, which has happened in other cases where blood types are incompatible.
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.
People with B blood type are thoughtful and empathetic towards others and make good and reliable friends. These people also face a lot of discrimination because of their negative personality traits such as selfishness and being uncooperative at times.
AB positive blood type is known as the “universal recipient” because AB positive patients can receive red blood cells from all blood types.
Famous Type O personalities: Queen Elizabeth II, John Lennon or Paul Newman.
CHANGES in blood type have been described in a variety of illnesses, usually acute infections or neoplasms.
Brothers and sisters don't always share the same blood type. The genotype of both parents plays a role in defining the blood type. For instance, children of parents with the genotypes AO and BO may have the blood types A, B, AB, or O. Thus, siblings do not necessarily have the same blood type.
Royals became known as 'blue bloods' because of their noticeable veins. Pale white skin came to be associated with wealthy royal families, who could afford to spend their times inside their mansions and palaces.
They pack supplies of their own blood
But in order to do an blood transfusion, you need to have a doctor on hand, which is why a Royal Navy doctor accompanies every royal on his or her trip for emergencies.
