1

Generates a complete CBC using EDTA whole blood
0.5-1.0 mL of blood needed
Uses laser flow cytometry
Cells are analyzed on 5 perameters

Lasercyte

2

5 perameters Lasercyte tests for with blood cells

lobularity, nucleus:cytoplasm ratio, cellular volume, cellular density, and granularity

3

Tests organ functions using dry slide technology
12 chemical tests simultaneously
Serum or plasma

VetTest Chemistry Analyzer

4

The preferred sample for the VetTest in what kind of tube?

Plasma from a heparin tube (green top)

5

Two color boxes for reagent slides
Where should they be stored?

Green and purple; freezer

6

Reagent slides need to be used within how many minutes of opening the foil packet?

15 minutes

7

With these samples, you must allow the blood to clot before centrifuging. How long does it take to clot?

Serum; 20-30 minutes

8

When centrifuging a serum sample, how long should it be spun?

10-20 minutes

9

Why must you use a lithium-heparin tube for the VetTest?

Ca in the blood binds to EDTA

10

2 Kidney tests performed by the VetTest

BUN and CREA

11

Increases with renal dz, starvation, and dehydration

BUN
Blood Urea Nitrogen

12

Accumulation of metabolic waste in the blood (urea, specifically)

azotemia

13

Byproduct of protein metabolism

Blood Urea Nitrogen (BUN)

14

Byproduct of muscle metabolism

Creatinine (CREA)

15

Used in conjunction with BUN test to diagnose kidney dz

CREA

16

Clinical signs of kidney dz are seen after how much of the kidney is compromised?

75%

17

Clinical signs are only seen after the liver has lost how much of it's functioning ability?

80%

18

This organ has regenerative capabilities

Liver

19

Liver specific
Created by hepatocytes
Increased levels present with liver dz, trauma to the liver, and toxins

SGPT
AKA ALT

20

Not liver specific
Synthesized in liver and cardiac and skeletal muscles

SGOT
AKA AST

21

The byproduct of hemoglobin metabolization
Not liver specific
Increases seen with hepatic lipidosis, hemolytic anemia, hyperthyroidism, and pancreatitis

Billirubin (TBIL)

22

Main protein of blood plasma made by liver cells
Decrease is more common than increase; decreases can be caused by heartworm dz, ehrlichia, and IBD
Levels below 1.0g/dL are dangerously low

Albumin (ALB)

23

Pancreatic function tests include

AMYL, LIPA, and GLU

24

Breaks down starches and glycogen in sugars
Increases can be seen with renal failure or peritonitis
Acute or chronic pancreatitis can cause this as well

Amylase (AMYL)

25

Assists in breaking down fatty acids
Values are usually parallel to amylase values
Increases seen with pancreatitis, liver and renal dz

Lipase (LIPA)

26

Evaluates insulin production
Blood must be centrifuged immediately because this binds to RBCs and decreases by 10% per hour
Stress can increase values
Below 60 mg/dL is dangerously low

Glucose (GLU)

27

A patient testing for their glucose levels should fast for how long before the test?

16-24 hrs

28

Plays important role in steroid production and levels are helpful in diagnosing hypothyroidism and Cushing's dz

Chlesterol (CHOL)

29

Used to determine the hydration levels of a patient

Total Protein (TP)

30

NOT AN ELECTROLYTE
Most abundant MINERAL in the body
Important role in muscle contraction and blood clotting

Calcium (Ca)
