8. Differential WBCC Record each type of WBC you see, until you have recorded 100 cells. Calculate percentages

9. Blood Groups Why is it important to match blood groups for donors and recipients? Agglutination: the clumping of RBC’s Antigens: surface molecules on RBC’s Antibodies: proteins in the plasma that attack “foreign” bodies

10. ABO Blood Group Based on the absence or presence of 2 major antigens on RBC surfaces: – Antigen A – Antigen B The presence/absence of these antigens combines to form 4 blood types: 1.Type A = A antigens only (41%) 2.Type B = ??? (9%) 3.Type AB = ??? (3%) 4.Type O = ??? (47%)

11. ABO Blood Group, continued….. If you lack antigen A on your RBC’s, then you will have antibody A in your plasma. Blood TypeAntigens Present on RBC Antibodies Present in Plasma 1. 2. 3. 4.
