O Negative Blood Type
O negative blood type is one of the four main blood types, classified by the ABO blood group system. It is unique because it has no A or B antigens on the surface of red blood cells, making it a universal donor type. This means that people with O negative blood can donate to anyone, regardless of their blood type, which is crucial in emergency situations.
Individuals with O negative blood can only receive blood from other O negative donors. This blood type is relatively rare, found in about 7% of the population. Due to its universal donor status, it is often in high demand in blood banks and hospitals, especially during emergencies or natural disasters.
