Lab Review - Lab Tests Flashcards
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
5 perameters Lasercyte tests for with blood cells
lobularity, nucleus:cytoplasm ratio, cellular volume, cellular density, and granularity
Tests organ functions using dry slide technology
12 chemical tests simultaneously
Serum or plasma
VetTest Chemistry Analyzer
The preferred sample for the VetTest in what kind of tube?
Plasma from a heparin tube (green top)
Two color boxes for reagent slides
Where should they be stored?
Green and purple; freezer
Reagent slides need to be used within how many minutes of opening the foil packet?
15 minutes
With these samples, you must allow the blood to clot before centrifuging. How long does it take to clot?
Serum; 20-30 minutes
When centrifuging a serum sample, how long should it be spun?
10-20 minutes
Why must you use a lithium-heparin tube for the VetTest?
Ca in the blood binds to EDTA
2 Kidney tests performed by the VetTest
BUN and CREA
Increases with renal dz, starvation, and dehydration
BUN
Blood Urea Nitrogen
Accumulation of metabolic waste in the blood (urea, specifically)
azotemia
Byproduct of protein metabolism
Blood Urea Nitrogen (BUN)
Byproduct of muscle metabolism
Creatinine (CREA)
Used in conjunction with BUN test to diagnose kidney dz
CREA
Clinical signs of kidney dz are seen after how much of the kidney is compromised?
75%
