The useful idea
- Blood is classified
A blood type (also known as a blood group) is a classification of blood based on the presence and absence of antibodies and inherited antigenic substances on the surface of red blood cells (RBCs).
- Antigens appear elsewhere
Some of these antigens are also present on the surface of other types of cells of various tissues.
- Compatibility matters
The two most important blood group systems are ABO and Rh; they determine someone's blood type (A, B, AB, and O, with + or − denoting RhD status) for suitability in blood transfusion.
Why this matters
Use Blood type to ask clearer questions; personal health decisions still belong with a qualified professional.
