Presentation Transcript

  1. Blood Typing ABO

  2. Discovery Education streaming - Asset Details • Go to Discovery Education • Click on Video Segment (6:02)

  3. ABO Blood Group • Three alleles A, B, O • or IA, IB, i • Phenotypes of Blood types: • A • B • AB • O NOTE: A and B are codominant

  4. Drop of Blood Red blood cells have antigens Plasma has antibodies Don’t mix same letter antigens with antibodies

  5. Antigens on RBC antigens antibodies

  6. Antigens on surface Rh A

  7. B antigens on surface Rh B

  8. Both A and B antigens on surface Rh

  9. Agglutination (clumping)Animation: Cytotoxic (Type II Hypersensitivity)

  10. Official Blood Test Card

  11. Blood Typing Simulation • A sera is colored blue • B sera is colored yellow • Rh sera is colorless

  12. ABO Blood Type • ABO Blood Typing

  13. Type A + A Rh B

  14. Type B Pos A Rh B

  15. Type AB+ A Rh B

  16. Type O neg. A Rh B

  17. Rh+ and Rh- dominant Rh positive gene (+) produces the Rh antigen recessive Rh negative gene (-) does not produce an antigen

  18. Rh+/Rh+ Rh+/Rh- Rh+ Rh-/Rh- = Rh-

  19. (DD) or (Dd) = Rh+  (dd) = Rh- (they do not have the key Rh antigens).

  20. Rh + or - ? Anti-Rh antibodies .

  21. O positive and negative blood

  22. Donating Blood

  23. Best Blood • If you include the Rh factor, then the universal donor becomes O Negative while the universal recipient becomes AB Positive.

  24. Percentages in U.S. • O Positive 38.4% • A Positive 32.3% • B Positive 09.4% • O Negative 07.7% • A Negative 06.5% • AB Positive 03.2% • B Negative 01.7% • AB Negative 00.7%
