Homonym: O positive (Blood)
"O positive" refers to a specific blood type in the ABO blood group system. It means that a person has type A and type B antigens on the surface of their red blood cells, along with the presence of the Rh factor, which is a protein that can be present (+) or absent (-). This blood type is one of the most common, making it crucial for blood donations and transfusions.
Individuals with O positive blood can donate to any positive blood types, including A positive, B positive, and AB positive. However, they can only receive blood from O positive and O negative donors. Understanding blood types is essential for safe medical procedures and emergency situations.
