Blood types were first discovered in 1900 by Karl Landsteiner who found that blood from different people would clump together in test tubes. The main blood types are A, B, AB, and O determined by the presence of antigens on red blood cells. People with type A blood can donate to A and AB, while type B to B and AB, type O to all, and type AB only to AB. Each blood type is believed to correlate with certain personality traits and dietary recommendations like type A being vegetarian oriented and type O avoiding wheat and dairy.

3. INTRODUCTION
• A blood type (also called 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).
• These antigens may be proteins, carbohydrates, glycoproteins, or glycolipids,
depending on the blood group system.
• Some blood types are inherited and represent contributions from both parents.
• The two most important ones are ABO and the Rh blood group systems; they
determine someone's blood type (A, B, AB and O, with +, − or null denoting RhD
status) for suitability in blood transfusion.

4. HISTORY OF BLOOD
TYPES
• Blood types were first discovered by an Austrian Physician Karl
Landsteiner working at the Pathological-Anatomical Institute of the University of
Vienna (now Medical University of Vienna).
• In 1900, he found that blood sera from different persons would clump together
(agglutinate) when mixed in test tubes, and not only that some human blood also
agglutinated with animal blood

6. TYPE:- A,B,O,AB
 TYPE A
• The blood type, you can donate red blood cells to types A and AB.
• The makeup of a person’s antigens on red blood cells can determine how much of
a certain hormone gets released. If you have type A blood, you're more likely to
have higher levels of the stress hormone cortisol in your body.
 TYPE B
• The type of blood type, you have type B blood, you only have the B antigens on red
cells and A antibodies in the plasma; you can donate red blood cells to those with
types B and AB blood.
• Those with type B have an 11 percent increase in risk of heart disease.
 TYPE O
• If you fall into the O blood group, you have neither A nor B antigens on your red
cells, but both A and B antibodies in your plasma. O positive is the most common
blood type; O negative is the universal donor type, meaning those with this blood
type can donate red blood cells to anybody.
 TYPE AB
• Those with AB blood have both A and B antigens on red cells, but neither A nor B
antibody in the plasma. If you have AB positive blood, you are universal plasma
donor.
