It is often discussed in relation to blood transfusions, pregnancy, and genetic inheritance. - As a subject: "Rh-positive blood type is the most common in the population." - As an object: "The test confirmed she has an Rh-positive blood type." - With a possessive: "His Rh-positive blood type meant he could safely receive the transfusion."
