CVA Laboratory Techniques & Diagnostic Procedures 2

Question 1

Which tube color is used to collect blood for a serum chemistry panel?

Accepted Answer

Red or gold top (no anticoagulant)

Answer

Red or gold top tubes contain no anticoagulant, allowing blood to clot so serum can be separated for chemistry analysis.

Question 2

When performing a urine specific gravity measurement with a refractometer, the result is 1.045 in a dog. This indicates:

Accepted Answer

Concentrated urine

Answer

A specific gravity above 1.030 in dogs indicates concentrated urine, reflecting adequate renal concentrating ability.

Question 3

What is the primary purpose of Diff-Quik stain in veterinary diagnostics?

Accepted Answer

Rapid staining of blood smears and cytology samples

Answer

Diff-Quik is a rapid Romanowsky-type stain used to differentiate cell types on blood smears and cytology preparations.

Question 4

A fecal flotation test uses a solution with high specific gravity to:

Accepted Answer

Float parasite eggs to the surface for collection

Answer

The high-density flotation solution causes parasite eggs and oocysts to rise to the surface where they are collected on a coverslip.

Question 5

Which laboratory value is most useful for evaluating kidney function in veterinary patients?

Accepted Answer

BUN (blood urea nitrogen) and creatinine

Answer

BUN and creatinine are the primary markers of renal function because they are filtered by the kidneys and accumulate when kidney function declines.
