1

______ volume determines what percent of whole blood is made up of red blood cells via centrifugation

Pack Cell volume 

2

______ are immature red blood cells 

Reticulocytes 

*if we know how many reticulocytes are present then we know if the anemia is regenerative 

3

If a patient has regenerative anemia, what are the other two possible causes for the anemia? 

Blood loss or Blood destruction

*Bone marrow is working because it is regenerative 

4

A cat presents with Lethargy and polydypsia. The cat has a regenerative anemia and an increased ________, therefore this is most likely a blood destructive anemia 

Protein

*Bone marrow is working properly since the anemia is regenerative and the total protein is increased. With blood loss you normally lose protein 

5

The lymphopenia in this Leukogram is due to _____

Stress

*Most sick animals will have a lymphopenia 

6

Low lymphocytes are very common in _____ animals 

Stressed 

7

The most common cause of Heinz Body anemia is _______ toxicosis 

Acetametaphine 

8

What species is most susceptible to Heinz body formation?

Cats 

 

9

Only thing that causes high Albumin in a patient

Dehydration 

10

If a patient has high glucose and low phospohorous, what disease should we be thinking about?

Diabetes Mellitus 

*phosphorus is eliminated through the kidneys 

11

If ALT enzyme is increased, there is usually damage to what organ?

Liver

*ALT is a liver enzyme 

12

A lethargic and polydypsic cat comes into the clinic. He is anemic and

you see heinz body formation on a blood film. The cats has a high measured Glucose and a low Phosphorous. Bilirubin, Cholesterol, and ALT are all above the reference interval. Most electrolyte counts are low. What is the most likely diagnosis in this cat? 

Diabetic cat with ketoacidosis and secondary heinz body formation 

 

13

True/False: Electronic counting machines can distinguish banned neutrophils from segmented neutrophils 

False

*Cannot distinguish 

14

Banned neutrophils are an indication of _______

Inflammation 

15

When Red blood cells are counted manually after centrifugation it is known as the Pack Cell Volume. What is it known as when the Red blood cells are calculated with an equation? 

Hematocrit 

16

The _____ the RDW, the more variable the sizes of red cells that are present 

Higher 

17

Patient is having periodic episodes of weakness and presents with an enlarged abdomen. What is the diagnosis?

Hemangiosarcoma in the abdomen

*Rupturing every couple days leading to weakness 

 

18

An increased MCV coincides with a _____ anemia 

Regenerative 

*Increased number of reticulocytes leads to an increased MCV

19

If you see Acanthocytes and Schistocytes in a blood film you should be suspicious of what disease?

Hemangiosarcoma 

20

Spherocytes are diagnostic for ______

Immune mediated hemolytic anemia 

21

What is the diagnosis in this dog?

Immune mediated Hemolytic anemia

*Spherocytes are very diagnostic for IMHA 

22

Dogs with immune mediated hemolytic anemia usually have _____, which is commonly the cause of death in these animals

DIC 

23

What is the diagnosis in this puppy that is not growing adequately?

Hookworm leading to chronic blood loss 

*Do a fecal exam to confirm diagnosis 

24

What is the main cause of a Microcytic anemia?

Iron deficiency 

25

If an animal has a non regenerative anemia with a normal total protein, what is the most likely cause of anemia?

Bone marrow insufficiency 

26

What is the diagnosis for this patient that is bleeing from the gums?

Bone Marrow failure 

*Bleeding due to severe thrombocytopenia 

27

What is the best anticoagulant to use for a CBC because it preserves cell morphology?

EDTA 

*Lavendar/purple top tube

28

What color tube conains the anticoagulant EDTA, which preserves cell morphology, and is used for blood collection for CBC?

Lavender 

29

Someone collects blood for CBC into a lavender tube, they end up deciding just to run a chemical profile and poor the blood into a red top tube. How will the chemical profile come back?

Extermely high potassium 

Extermely low calcium 

* Animal would not be alive if calcium was this low

30

If you are out in the field and cannot get a blood sample to the lab for about 4-5 hours, you should use a ____ top tube because it will inhibit glucose metabolism

Gray 

*Glucose decreases 10% per hour in a red top tube
