A urinalysis is one of the simplest tests in veterinary medicine, and one of the most revealing. By examining a small sample of your pet’s urine, our veterinary team can spot early signs of kidney disease, diabetes, urinary tract infections, and other conditions long before your dog or cat shows obvious symptoms. For pet parents in Hawthorne, CA, understanding when this test matters can mean the difference between catching a treatable problem early and discovering it only after it has progressed.
At Rosecrans Veterinary Clinic, we run urinalysis testing as part of routine wellness visits and as a targeted diagnostic tool when a pet’s symptoms point toward the urinary tract or a related organ system. It is quick, minimally invasive, and often paired with bloodwork to give a fuller picture of your pet’s internal health.
Pet parents sometimes assume that a urine test only matters when a dog or cat is already showing signs of illness. In reality, many of the conditions this test detects, especially kidney disease and diabetes, develop quietly for months or years before a pet’s behavior changes at home. Building urine testing into your pet’s regular care schedule gives our veterinarians a baseline to compare against later, which makes it much easier to spot a meaningful change when one occurs.

What Is a Urinalysis for Pets?
A urinalysis is a laboratory or in-clinic examination of a pet’s urine sample that looks at three main things: physical appearance, chemical composition, and microscopic content. Our veterinary team collects the sample, then evaluates its color, clarity, and concentration before running a chemical strip test and, when needed, a microscopic review of any cells, crystals, or bacteria present. This test is one of several diagnostic services we offer to catch health issues early.
The physical exam checks color and cloudiness. Urine that is unusually dark, pale, or cloudy can be an early clue that something is off, even before other symptoms appear. The chemical portion of the test uses a dipstick to screen for substances that should not normally be present in significant amounts, including:
- Glucose, which may point toward diabetes
- Protein, which can signal kidney stress or infection
- Ketones, associated with metabolic imbalances
- Blood, which may indicate infection, inflammation, or bladder stones
- Bilirubin, which can suggest liver involvement
Finally, the microscopic exam looks at sediment left after the sample is spun in a centrifuge. This step reveals red and white blood cells, bacteria, and crystals that are not visible to the naked eye but carry real diagnostic weight. Rosecrans Veterinary Clinic uses in-house IDEXX equipment, including our SediVue analyzer, so many of these results are available the same day your pet is seen.
How the sample is collected depends on what we are looking for. A free-catch sample, taken as your pet urinates naturally, works well for a general screening. When a more precise reading is needed, particularly to rule out a bladder infection without contamination from the lower urinary tract, our veterinarians may recommend cystocentesis, a quick and well-tolerated procedure where a small needle is used to draw urine directly from the bladder. Our team will always explain which method fits your pet’s situation and why.
What Diseases Can a Urine Test Detect in Dogs and Cats?
A urine test can detect a wide range of conditions, from urinary tract infections to early kidney disease and diabetes, often before a pet shows any outward signs of illness. Because the kidneys filter waste directly into urine, changes in kidney function frequently show up here well before they appear on a physical exam.
Some of the most common findings include:
- Urinary tract infections, identified through bacteria, white blood cells, or blood in the sample
- Chronic kidney disease, often first suggested by dilute urine or elevated protein levels
- Diabetes mellitus, indicated by glucose appearing in the urine alongside elevated blood sugar
- Bladder or kidney stones, suggested by certain crystal types or visible blood
- Liver disease, which can alter bilirubin levels in the urine
Cats are especially good at hiding illness until a condition is fairly advanced, which is one reason senior cats in particular benefit from routine urine screening even when they seem perfectly healthy at home. A cat’s inability to concentrate urine properly, reflected in a measurement called specific gravity, is often one of the earliest signals of declining kidney function, sometimes showing up before bloodwork changes are significant enough to raise concern on their own. Dogs with sudden changes in thirst, appetite, or bathroom habits often have their urinalysis results confirm what their behavior was already hinting at.
It is worth noting that a urinalysis rarely stands alone as a final diagnosis. Our veterinarians typically pair the results with bloodwork and, when appropriate, imaging to confirm what the urine sample suggests and rule out other causes. For example, a dog with both elevated blood glucose and glucose present in the urine gives us much stronger confirmation of diabetes than either result would on its own, and it helps rule out temporary stress-related blood sugar spikes, which are common in cats during a veterinary visit.
When Should Pets Have Urine Testing?
Pets should have urine testing during routine wellness visits, before certain surgical or anesthetic procedures, and any time new symptoms suggest a urinary or metabolic problem. For healthy adult dogs and cats, an annual urinalysis alongside their regular pet checkups is a reasonable baseline, and many pet parents choose to combine it with their pet’s regular bloodwork.
Senior pets, generally those eight years and older, benefit from more frequent testing. Aging bodies are more prone to kidney decline, diabetes, and other conditions that a urinalysis can catch early, when treatment options are broader and outcomes tend to be better.
Beyond routine screening, we recommend bringing your pet in for urine testing if you notice any of the following:
- Increased thirst or water consumption
- More frequent urination, or accidents from a previously house-trained pet
- Straining, crying, or visible discomfort while urinating
- Blood in the urine or a sudden change in color or odor
- Unexplained weight loss or lethargy
Urine testing is also a standard part of pre-anesthetic screening before spays, neuters, dental cleanings, or other procedures, since it helps confirm that a pet’s kidneys are functioning well enough to safely process anesthesia.
Puppies and kittens are not left out either. A baseline urinalysis during early wellness visits can flag congenital kidney or urinary tract issues while they are still easiest to manage. If your pet’s test requires a specific collection method or timing, such as an early morning sample, our team will walk you through exactly what to do before your appointment so the results are as accurate as possible.
