What is Rh-negative type O blood?

Rh-negative O-type blood is a rare blood type, commonly referred to as “panda blood.” This blood type is extremely uncommon, representing only a small fraction of the general population. Individuals with Rh-negative blood must exercise caution in daily life to avoid injury, as such blood is found in only about one in several hundred thousand people. In cases of trauma requiring blood transfusion, obtaining compatible blood may prove challenging.
