What time frame can we run a fresh urine should be evaluated within 2-4 hours of
urinalysis within? collection for the most valid results.
Ms. D says that we need to run it within the first 30
minutes...
What can we evaluate with the renal function values
urinalysis? protein concentrations
metabolic functions
What is a "complete urinalysis"? the evaluation of the physical (color, clarity and
specific gravity), chemical, and formed element
characteristics of urine
What are the two preferred methods cystocentesis
for urine collection? catheterization
What are the two less useful free-catch
methods of urine collection? bladder expression
What should we keep in mind if the midstream to decrease contamination
only way to get a sample is to do a
free catch?
, What kind of abnormalities do we We need to obtain cysto or catheterized samples
need a NON free catch for? for problems related to disease in the kidneys or
urinary bladder
What are some problems with possibility of rupturing the bladder if excessive
bladder expression? pressure is used or if the bladder wall is
compromised.
When should we get a urinalysis A first morning sample will provide the best

What is the best time to get a u/a to first stream of the morning
evaluate urine for casts?
Why do we do the u/a ASAP after because cellular element and crystals can
collecting the sample? deteriorate, making it difficult to recognize them
correctly. Plus, crystals can dissolve over time.
How long can we postpone running a sample can be refrigerated for 6 hours - NO
a urinalysis? LONGER.
What do we have to remember Sample needs to return to room temperature
about a sample if it has been before running any tests on it.

What chemical parameters do we Several indicator pads on reagent strips are
worry about with refrigerated enzyme-based runs, and the speed of rxn
samples? decreases as the temperature decreased -
therefore causing false-negatives/positives
