Question 2

erythrocytosis

Answer 2

increased PCV. Also known as polycythemia

Question 3

Answer 3

lipemia, hemolysis, or Heinz bodies

Question 4

Question 5

Question 6

MCV

Answer 6

average volume of circulating RBC

Question 7

What is the PCV threshold for severe anemia in dogs and cats

Answer 7

24 for dogs and 23 for cats

Question 8

what can cause macrocytosis

Answer 8

storage of a sample: Causes rbc to swell
Reticulocytosis
Rbc agglutination: Scanner sees these as one cell

Question 9

Metarubricotysis

Answer 9

increased nucleated RBC. Usually a sign of bone disease/damage

Question 10

Reticulocytosis suggests what?

Answer 10

iron deficiency

Question 11

If you take a blood sample one hour after an acute hemorrhage, what would you expect to see on the cbc

Answer 11

drop in HCT and reduced total plasma protein. No change in retic# yet.

Question 12

What could be seen in a blood smear of a patient with iron deficient anemia

Answer 12

hypochromic cells
Poikilocytosis-schistocytes
Thrombocytosis- increase in platelets
Microcytosis

Question 13

Hemolytic anemia signs

Answer 13

Inc Bu
Increase Retic#
Pink plasma

Blood smear could show ghost cells or spherocytes- no central palor
