    reticulocyte concentration
  2. What are reticulocytes and what type of stain is best used to see them?
    • immature RBC w/ organelles present
    • NMB

  7. What is the average lifespan of a canine RBC?
  8. What is the average lifespan of a equine RBC?
  9. What is the parasite name for feline Hemobartonella?MH
    mycoplasma haemofelis
  10. What is the common name for mycoplasma haemofelis?FIA
    feline infectious anemia
  11. When looking for feline hemobartonella, which stain is used?
    wright's stain
  12. When looking at feline hemobartonella, why should you use whole blood instead of anticoagulated blood?
    b/c these will cause the organism to detach from the cell wall
  13. Babesia canis is a blood parasite commonly aquired how?
    through the bite of the brown dog tick
  14. Babesia canis is the causing agent of what dz?P

    • stacking of RBC's
    • horses
  16. What is agglutination?
    How does it occur?
    • clumping of RBC's
    • antibodies to the RBC's are present on the cell wall causing them to stick
  17. Anisocytosis
    abnormla variation in RBC size
  18. Poikilocytosis

    shearing from intravasuclar trauma
  22. When are schistocytes seen?DVI
    • DIC
    • vascular neoplasias (hemangiosarcomas)
    • iron deficiency
