1
A red square featuring a bold "O" at its center, used to indicate blood type O.
2
A red square bearing the letter O typically denotes blood type O. Because that meaning isn’t always obvious, the emoji is also commonly used simply to represent the letter O.
It’s often used in a medical context — for example, to suggest a hospital or treatment — and pairs well with the syringe emoji.
