Blood Group O

Blood group O has neither A nor B antigens on red blood cells but contains both anti-A and anti-B antibodies in the plasma. Individuals with this blood type can donate red blood cells to anyone (universal donor) but can only receive blood from group O. Blood group O is the most common blood type in many populations. Because it lacks A and B antigens, it plays a crucial role in emergency transfusions.
