1
Q

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

A

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

2
Q

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

A

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
Q

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

A

Macrocytic regenerative - polychromatophils can be seen, larger than RBCs

  • Poodles
4
Q

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

A

Hypochromic cells, relating to Hbg conc

  • Fe insufficiency or incorporation -> microcytosis (cells are thinner hence appear paler, not necessarily a decrease in diameter)
5
Q

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

A

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
Q

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

A

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

7
Q

What signs of regeneration can be seen on these smears?

A

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

8
Q

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

A

Ghost cell - not sure what this shows!

9
Q

What abnormal RBC morphology can be seen here?

A

Shear products (keratocytes, shistocytes, acanthocytes)

10
Q

What can be seen here? What does this indicate?

A

Heinz bodies, indicate oxidative damage

11
Q

What are these cells? What do they indicate?

A

Band neutrophils - indicate left shift (Acute infection)

12
Q

What has happened here?

A

Platelet clumping
