Blood Types
Blood types depends on surface antigens (Agglutinogen) on erythrocytes• O-A-B blood types• Rh blood type• Others: Rh, MNSs ,Kidd, Lutheran ,Kell etc

O-A-B blood type
Depending on presence or absence of antigen (Agglutinogen),four different blood groupsA--if only agglutinogen A is presentB--if only agglutinogen B is presentAB--if both agglutinogen A and B are presentO--if neither agglutinogen A nor agglutinogen B are present

Landsteiner,s Law• If a particular agglutinogen is present on RBC,
corresponding agglutinin must be absent in serum
• If a particular agglutinogen is absent on RBC, corresponding agglutinin must be present in serum
This law does not apply to Rh system

Titer of Agglutinins at different Ages• Immediately after birth– zero• Two - eight months of age – begins to produce• Eight- ten years of age – maximum titer• Then gradually declines throughout life
Origin of Agglutinins in Plasma• Food• Bacteria

• Inheritance• Universal donors• Universal Recipients• Autologous transfusion• Secretors and non- secretors
