What does “Rh-positive blood type” mean?

Rh-positive blood type is relatively common in China; the majority of people have Rh-positive blood. The distinction between Rh-positive and Rh-negative blood types is determined by the presence or absence of the Rh factor. Rh-negative blood type—also known as “panda blood”—is rare. Individuals with Rh-negative blood should take precautions to avoid physical trauma that could cause injury and excessive bleeding. During pregnancy, regular prenatal check-ups are essential to prevent hemolytic disease.
