What is "blood type"?
Blood type refers to the classification of blood based on certain substances found on red blood cells. The main blood types are A, B, AB, and O, depending on which substances are present or missing. Blood can also be either Rh-positive or Rh-negative, which means it has or does not have an additional substance called the Rh factor. Knowing a person’s blood type is crucial for safe blood donations and organ replacements, as matching the blood types helps avoid dangerous reactions.
