Answer 1

hemogram
CBC

plasma protein
RBC
WBC
platelets

Question 3

one of the most useful clinical evals done on the patient

Answer 3

CBC

Question 4

what can the results of the CBC reflect

Answer 4

health status
clues on pathologic condition

Question 5

the volume of packed erythrocytes measures and expressed as a percentage of a total volume of blood

Answer 5

packed cell volume (PCV) or hematocrit (HCT)

Question 6

what can excess red blood cell breakdown cause

Answer 6

jaudice/icterus

Question 7

If the amount of unconjugated bilirubin exceeds the ability of the liver to conjugate it, where is excess unconjugated bilirubin deposited - causing jaundice/icterus.

Answer 7

in tissues

Question 8

what are the three layers in the tube spun by the hematocrit centrifuge

Answer 8

top - plasma
middle - buffy coat
bottom - RBC

Question 9

in a dog, what are the percentages of the three layers in the tube spun by the hematocrit centrifuge

Answer 9

top plasma - 54%
middle buffy coat - 1%
bottom RBC - 45%

Question 10

two methods for determining PCV or HCT

Answer 10

automated blood analyzers

gross exam of centrifuged microhematocrit tube

Question 11

blood analysis that measures the concentration of hemoglobin contained in the RBC in a specific volume of blood

Answer 11

Hemoglobin analysis (Hgb)

Question 12

blood analysis that measures the number of red blood cells in a specific volume of blood

Answer 12

Red blood cell count (RBC count)

Question 13

measures the average volume or size of the individual RBC, helpful way to evaluate the erythrocytes in the sample, especially when anemia is present

Answer 13

mean corpuscular volume (MCV)

Question 14

a numerical expression of variation in RBC size

Answer 14

red cell distribution width (RDW)

Question 15

variation in size from cell to cell in a blood sample

Answer 15

anisocytosis

Question 16

what is a sign of anemia is the red cell distribution width (RDW)

Answer 16

marked anisocytosis - RBCs are being pumped out at such a high rate that they don’t have time to fully mature

Question 17

immature RBCs are what, compared to fully mature RBC already in circulation

Answer 17

larger

Question 18

a count of the number of immature forms of the red blood cells per a specific total number of red blood cells - used to characterize the type of anemia in an animal

Answer 18

reticulocyte count (RETIC)

Question 19

expresses the total number of white blood cells in a specific volume of blood, number of each type of WBC is also counted

Answer 19

total leukocyte count (WBC count)

Question 20

increased number of neutrophils will also increase what

Answer 20

the total number of WBC in the sample

Question 21

increased number of WBC in the blood

Answer 21

leukocytosis

Question 22

decreased number of WBC

Answer 22

leukopenia

Question 23

measures the total number of platelets (thrombocytes) in a specific volume of blood sample

Answer 23

platelet count (PLT)

Question 24

used to describe a higher than normal or lower than normal platelet count

Answer 24

thrombocytosis
thrombocytopenia

Question 25

measures the amount of protein in the plasma portion of a specific volume of blood, can be measured by an automated blood analyzer or by using a hand held refractometer

Answer 25

total plasma protein (TP)

Question 26

manually counting WBC types after a blood smear is stained

Answer 26

differential cell count or diff

Question 27

stain the contains blue and red-orange dyes

Answer 27

Wright’s stain

Question 28

modified Wright’s stain that is commonly used in clinical practice to stain a blood smear quickly

Answer 28

Diff Quick
