Presentation Transcript

  1. Blood & Blood Testing

  2. Blood cells

  3. Erythrocyte (RBC) Stacking allows for passage through narrow blood vessels

  4. Leukocyte (WBC) Have a nucleus Fight disease Neutrophils Eosinophils Basophils Monocytes/Macrophage Lymphocyte

  5. Granulocyte • This is a cell that shows granules (spots) after staining • Neutrophils • Eosinophils • Basophils

  6. WBC Granulocyte: Neutrophil

  7. WBC Granulocyte: Eosinophil Appears darker or more red than neutrophils due to larger granules

  8. WBC Granulocyte: Basophil

  9. Agranulocyte • This is a cell without granules • Monocytes /Macrophages • Lymphocytes

  10. WBC Agranulocyte: Monocyte (Macrophage) Nucleus can appear as several different shapes - Remember: No granules make cytoplasm much lighter than granulated WBC

  11. WBC Agranulocyte: Lymphocyte Relatively similar size as RBC Very little cytoplasm visible due to size of nucleus

  12. Platelets (Thrombocytes) Platelets can appear in clusters or singular

  13. Comparison of all cells together Platelet Erythrocyte Eosinophil Neutrophil Basophil Lymphocyte Monocyte

  14. Hematocrit – Packed cell volume (PCV) Percentage of erythrocytes in the blood

  15. Differential White Blood Cell Count (DIFF) • A test where the first 100 WBCs are categorized according to type. • This number can then be compared to normal % to determine type of illness. WBC DIFF

  16. Tallquist hemoglobin test Measures the amount of hemoglobin in the blood to help determine anemia

  17. Blood Typing

  18. Antigens Antigen Antigen No Antigens Antigens Located on the erythrocytes Determines blood type

  19. Antibodies Identifies a specific antigen located on the erythrocytes

  20. Agglutination • Clumping that occurs when antibodies join to antigens

  21. ABO system B A

  22. Rh antigen D
