1

What type of anaemia does this smear show? When would this be seen?

Q image thumb

Normochomic normocytic (erythrocytes all similar size) Seen with mild non-regenerative amaemia  

2

What type of anaemia does this smear show? When would this be seen?

Q image thumb

Microcytic, seen in Fe deficiency, PSS, hepatic failure (iron deficiency allows one more division of red cells as Hb concentration determines when division stops)

- may be seen in Akitas (congenital)

3

What type of anaemia does this blood smear show? What breed may be predisposed to this?

Q image thumb

Macrocytic regenerative - polychromatophils can be seen, larger than RBCs

- Poodles 

4

How would these cells be described? When are these kind of RBCs seen? 

Q image thumb

Hypochromic cells, relating to Hbg conc 

- Fe insufficiency or incorporation -> microcytosis (cells are thinner hence appear paler, not necessarily a decrease in diameter) 

5

What type of cell can be seen here? What does this indicate?

Q image thumb

Polychromatophil - indicates regeration as it is an immature RBC in the circulation. Will continue to mature in blood stream so may be pale blue. Have this appearance with Diff-Quik or Giemsa stains. 

6

What cells can be seen here? What are these the same as?

Q image thumb

Reticulocytes - same as polychromatophils but stained with new methylene blue to precipitate out the RNA

7

What signs of regeneration can be seen on these smears?

Q image thumb

Polychromasia, anisocytosis, macrocytosis, nRBCs, Howell-Jolly bodies [top right], codocytoisis, basophilic stippling [Bottom right]

8

What type of abnormal cell can be seen here? Ehat does this indicate?

Q image thumb

Ghost cell - not sure what this shows!

9

What abnormal RBC morphology can be seen here? 

Q image thumb

Shear products (keratocytes, shistocytes, acanthocytes) 

10

What can be seen here? What does this indicate?

Q image thumb

Heinz bodies, indicate oxidative damage 

11

What are these cells? What do they indicate?

Q image thumb

Band neutrophils - indicate left shift (Acute infection) 

12

What has happened here?

Q image thumb

Platelet clumping
