2. Which of the following statements is NOT correct in regards to the Greyhound breed?

a. Greyhounds, who are sighthounds, can have a red blood cell (RBC) count below the reference range.

b. The physiology behind red blood cell alterations in Greyhounds is proposed to be due to an adaptation to racing.

c. Greyhounds can have a mean corpuscular volume (MCV) above the reference range.

d. Greyhounds can have eosinophils with greyish cytoplasm and vacuolation, referred to as grey eosinophils.

3. Macrocytosis can be seen with vitamin B12 or folate deficiency.

a. true

b. false

4. Which of the following statements regarding platelets is correct?

a. Thrombocytosis is a condition where the platelet count is below the reference range.

b. If the thrombocytosis is marked, there is a risk of spontaneous hemorrhage due to a low platelet count.

c. Hereditary macrothrombocytopenia is the normal occurrence of enlarged platelets in elevated numbers.

d. All of the above.

e. None of the above.

5. Which of the following statements regarding hepatic enzymes is NOT correct?

a. ALT is one of the hepatocellular leakage enzymes.

b. ALP is a cholestatic liver enzymes.

c. ALT, AST and ALP are only present in the liver.

d. Elevations of ALP should be interpreted in conjunction with other liver enzymes and biochemistry parameters.

e. Although present in the liver, GGT has the highest tissue concentration in the proximal renal tubules and pancreas in dogs.

6. Which of the following statements regarding renal parameters is correct?

a. Urea and creatinine are used as surrogate markers of renal function, with an elevation in only one parameter commonly termed “azotemia.”

b. Urea is produced in the kidneys.

c. Greyhounds have both higher serum creatinine and SDMA then current reference levels, however this does not persist into retirement from racing.

d. Yorkshire Terriers are known to have higher urea levels than current reference levels.

e. Urine concentration is not required when assessing the type of azotemia present (pre-renal, renal and post-renal).

c. Miniature Schnauzers have been reported to have higher total protein and albumin levels compared to reference ranges.

d. Greyhounds have reduced ⍺ and increased β globulin fractions of serum protein levels. e. Serum samples contain EDTA, whereas plasma samples do not contain EDTA.

9. The following are cat breeds with known lab parameters outside of normal reference ranges, except for:
