| Urinalysis is an essential test for evaluating kidney function.
Whenever blood is collected for a chemistry profile, a urine sample
should be obtained whenever possible (especially on the initial sampling).
Changes in renal parameters cannot be interpreted without knowledge
of the urine results. For example, a high BUN and creatinine (azotemia)
in a dehydrated patient with a concentrated urine (urine specific
gravity > 1.030 in a dog) is compatible with a pre-renal azotemia,
whereas azotemia in a dehydrated dog with a USG of 1.010 indicates
a renal azotemia. Urine should be collected into sterile red-top containers
for all our tests.
We offer routine urinalysis, protein:creatinine ratios, and certain
individual urine chemistry tests. Fractional excretion of electrolytes
can be calculated by measuring the concentration of electrolytes
and creatinine in serum and urine. Urinary excretion of electrolytes
and certain enzymes, e.g. GGT, can indicate renal disease, e.g.
Fanconi's syndrome and aminoglycoside toxicity (urinary GGT). For
more information on these electrolytes and enzymes, refer to our
chemistry panels under Tests We Offer.
