O positive
Common blood type
O positive is the most common blood type, present in roughly 37% of people.
The O indicates the absence of A and B antigens on red blood cells, while positive means the Rh factor is present.
O positive blood can be given to anyone with a positive blood type, making it highly valuable for transfusions: The blood bank is always short on O positive.
