The human body contains one of four main blood types: A, B, AB and O.
Each blood-type also has an accompanying Rhesus or Rh factor of either positive or negative.
The most commonly found blood-type in the world is O positive while the rarest is AB negative.

From the U.S population it was determined that the percentages of blood types were as follows.
- O positive ~ 38.4%
- O negative ~ 7.7%

- A positive ~ 32.3%
- A negative ~ 6.5%

- B positive ~ 9.4%
- B negative ~ 1.7%
