1

What does increased MCV in an anemic animal suggest?

regenerative anemia

2

Name a breed of dog that may have increased MCV without being anemic.

poodle

3

Which are consistently seen with hemangiosarcoma (HSA) of the liver in dogs?

acanthocytes and schistocytes

4

Increased variation in the size of RBCs on a blood film is called?

anisocytosis

5

What best fits this description: small, irregularly shaped RBC fragment caused by mechanical trauma while in circulation within the vasculature

schistocyte

6

What doesn't describe a spherocyte?

they can be identified in most domestic species

7

List platelet artifacts caused by EDTA.

platelet clumping

8

On average, how many PLTs per OIF are considered adequate?

8-10

9

T/F The mean platelet volume is the average size of PLTs in the circulating PLT population.

true

10

List things seen on a smear with regenerative anemia.

polychromatahpils, anemia, howell-jolly bodies, nRBC, metarubricytes, basophillic stippling

11

What is a shift platelet?

immature platelet, size of RBC or bigger

12

Where is heartworm usually?

in the pulmonary arteries

13

What are examples of an elisa test?

idexx snap 3dx, snap 4 dx, dirocheck, cite heartworm test kits

14

What are examples of a lateral flow immunoassay test?

vetscan canine rapid heartworm test, synbiotics witness heartworm antigen test, heska solo step ch

15

How are the knotss test and antigen test different?

knotts is a concentration test for microfilaria and antigen is for the presence of adult heartworm

16

Acanthochelionema reconditum is what kind of filarid nematode?

subcutaneous

17

What is an occult infection?

harbors adult heartworms but will not have mff circulating in the peripheral blood

18

Compare & contrast canine and feline heartworm.

dogs: can be infected with many heartworm, likely to be antigen positive because of the presence of female heartworms, antibodies usually not helpful in the diagnosis, the heart and lungs are involved in this disease.
cats: usually infected with few heartworms, unlikely to be antigen positive because of few worms(few female worms), antibodies may be helpful in the diagnosis, the heart is not usually involved in disease (the lungs are severely infected)

19

What's the difference between aggregate and punctate reticulocytes in cats?

agg: type 1 polychromatophils
punc: type 2 more mature (older) do not stain as polychromataphils with Wright's type stains

20

T/F Punctate reticulocytes are unique to cats and the majority of the reticulocytes in cats are punctate.

true

21

T/F Punctate reticulocytes are less reliable than aggregate reticulocytes as indicators of the current demand for RBCs.

true

22

T/F Both aggregate and punctate reticulocytes should be counted in cats with mild anemia.

true

23

What does the FeLV/FIV SNAP test detect specifically?

FeLV p27 antigen and specific antibodies to FIV

24

Small, usually singular and round, basophillic nuclear remnants in the RBC cytoplasm

howell-jolly bodies

25

Multiple, small, dark blue, dot-like structures representing residual RNA in the RBC cytoplasm

basophilic stippling

26

A knob-like structure protruding from the RBC membrane or a small, pale, refractile spot in the RBC cytoplasm composed of denatured, precipitated Hb that is often attached to the inner cell membrane.

heinz bodies

27

T/F Because feline Hb is very susceptible to oxidation and cat spleens are inefiicent in removing heinz bodies from RBCs, up to 5% of the RBCs in healthy cats may contain howell-jolly bodies(erythrocyte refractile bodies or ER bodies)

false-heinz bodies

28

Which test is for qualitative detection of D. immitis in canine whole blood, serum, or plasma?

VetScan Canine Heartworm Rapid test

29

What doe the Canine Heartworm SNAP 3Dx test for?

D. immits antigen, antibody to B. burgorferi, and antibody to E. canis

30

Canine heartworm is a what?

filarid nematode
