A person’s blood type is based on whether or not they have certain molecules or proteins — called antigens — on the surface of their red blood cells, according to the National Institutes of Health. Two of the main antigens used for blood typing are known as “A antigen” and “B antigen.” People with type A blood only have A antigens on their red blood cells and those with type B blood have only B antigens. Individuals with type AB blood have both; people with type O blood have neither.

Another protein, the “Rh factor” – also known as the “Rhesus” system – is also present or absent on red blood cells. A person’s blood type is designated as “positive” if they have the Rh protein on their red blood cells, and “negative” if they don’t have this protein.

A person’s blood type is genetic, inherited from his or her parents, according to the Red Cross.

Blood typing is particularly important for blood transfusions, because certain antigens on blood cells can trigger a person’s immune system to attack the donated blood.

People who are Rh-negative can only receive Rh-negative blood, but people who are Rh- positive can receive either Rh-positive or Rh-negative blood, the Red Cross says.

What’s more, type A blood can be used for transfusions for patients with type A or type AB blood; type B blood can be used for patients with type B or type AB blood; and type AB blood can be used for patients with type AB blood. People with type O blood are called “universal donors” because this type can be used for patients with any blood type.

Type O blood is often in short supply in hospitals, due to demand for this universal donor type, according to the Red Cross. In particular, type O-negative blood is in high demand because it’s the one most often used for emergencies, when there may not be time to determine a patient’s blood type.

  1. RH- negatives seem to more ancient line than even apes. Mainstream science censors the fact that “lack of antigen” isn´t a random mutation, but RH-negatives have different proteins, amino acids and nucleotides even in their brains. The international Encode project has found out that fifth of the human genome codes and regulates proteins (which are different in pure Caucasian RH-negatives). Differences go in RNA, which also indicates to another species and another “evolution” path. This, of course is a difficult subject to so called elite formed of rhesus/ape humans. There is a short video about this subject, also a petrified fossil that could be one of the ancestors of Rh-negatives and there´s not any hint of apes in that humanoid fossil much older than apes.

    There are numerous remnants of ancient advanced civilization, which likely manipulated genetically also ape humans. As a matter of fact, modern ape humans are an unnatural creation, talking apes, animals of hunter-gatherer background without any high cultural achievements of their own. And these apes try to write (or simply censor) also history of more developed cultures.
