What is Rh plus blood?

Rh plus blood refers to blood that carries the Rh factor, a specific protein found on the surface of red blood cells. If an individual's blood type is classified as Rh positive (e.g., A+, B+, AB+, O+), it means they possess this protein. The presence of the Rh factor is important in blood transfusions and pregnancy, as incompatibility can lead to complications. In contrast, Rh negative blood lacks this protein.
