Urinalysis & Urine Testing for Dogs & Cats
A Simple Test That Can Reveal Important Information About Your Pet’s Health
A urine sample may seem simple, but it can provide valuable information about your pet’s kidneys, bladder, metabolism and overall health. Many important medical conditions can be detected or monitored through urinalysis, often before obvious clinical signs develop.
At Lutwyche Veterinary Surgery, we perform many urine tests in our advanced IDEXX in-house laboratory, allowing us to obtain same-day results for many patients. This means we can diagnose illness sooner, begin appropriate treatment earlier and discuss your pet’s results during the same visit whenever possible.
Whether your pet is showing signs of urinary disease or is undergoing a routine health check, urinalysis is an important diagnostic tool that helps us provide the highest standard of veterinary care.
Why Might My Pet Need a Urine Test?
Your veterinarian may recommend urinalysis if your pet is:
- Drinking more water than usual
- Urinating more frequently
- Straining to urinate
- Passing blood in the urine
- Having accidents inside the house
- Losing weight
- Vomiting
- Lethargic
- Showing signs of kidney disease
- Being investigated for diabetes
- Undergoing a senior health check
- Having pre-anaesthetic screening before surgery
Urinalysis is also commonly recommended alongside blood testing because the two tests provide complementary information about your pet’s health.
What Can Urinalysis Detect?
Urinalysis helps us diagnose and monitor many common medical conditions.
Urinary Tract Infections (UTIs)
Urine testing can identify signs of infection and inflammation within the urinary tract and help determine whether further testing, such as urine culture, is required.
Kidney Disease
Changes in urine concentration are often one of the earliest indicators of kidney disease.
When combined with blood testing, urinalysis provides valuable information about how well your pet’s kidneys are functioning.
Diabetes Mellitus
Glucose or ketones in the urine may indicate diabetes and assist with monitoring diabetic patients.
Bladder Stones
Some urine samples contain crystals that may increase the risk of bladder stone formation.
Your veterinarian will interpret these findings together with your pet’s clinical signs and diagnostic imaging if required.
Protein Loss
Protein in the urine may indicate kidney disease or other underlying medical conditions requiring further investigation.
Hydration Status
Urine concentration provides important information about hydration and the kidneys’ ability to concentrate urine.
Advanced IDEXX Urinalysis Technology
At Lutwyche Veterinary Surgery, we’ve invested in advanced IDEXX diagnostic technology to provide fast, accurate laboratory testing.
Our in-house laboratory includes the IDEXX SediVue Dx® Urine Sediment Analyser, an advanced system that combines digital microscopy with artificial intelligence to evaluate urine samples quickly and accurately.
The SediVue Dx helps identify:
- Red blood cells
- White blood cells
- Bacteria
- Crystals
- Casts
- Epithelial cells
- Other urinary sediment
Combined with urine chemistry testing and interpretation by our experienced veterinary team, this technology allows us to diagnose urinary tract disease more efficiently and monitor many medical conditions with confidence.
Many urine test results are available on the same day, allowing treatment decisions to be made without unnecessary delays.
What Does a Urinalysis Include?
A comprehensive urinalysis may include:
- Urine specific gravity
- pH measurement
- Protein
- Glucose
- Ketones
- Blood
- Bilirubin
- Microscopic examination of urinary sediment
- Red blood cells
- White blood cells
- Bacteria
- Crystals
- Casts
- Epithelial cells
Every result is interpreted alongside your pet’s medical history, physical examination and any blood test findings to provide the most accurate diagnosis possible.
How Is a Urine Sample Collected?
Depending on your pet’s condition, urine may be collected in several ways.
Free Catch Sample
Many owners collect a fresh urine sample at home before their appointment.
This is suitable for many routine investigations.
Cystocentesis
A sterile needle is used to collect urine directly from the bladder.
This technique provides the cleanest sample and is commonly recommended when investigating urinary tract infections or when urine culture is required.
Urinary Catheterisation
Occasionally, urine may be collected using a urinary catheter if medically indicated.
Your veterinarian will recommend the most appropriate collection method for your pet.
Frequently Asked Questions
Should I bring a urine sample to my appointment?
If your pet is experiencing urinary signs and you are able to collect a fresh urine sample on the day of your appointment, this is often very helpful.
If you’re unsure how to collect a sample, our team is happy to provide guidance.
How fresh should the sample be?
Ideally, urine should be examined within a few hours of collection.
If immediate delivery is not possible, refrigerate the sample and bring it to your appointment as soon as possible.
Does every pet with urinary signs need a urine test?
In many cases, yes.
Urinalysis provides valuable diagnostic information that helps guide treatment decisions for pets with urinary problems, increased thirst, kidney disease or diabetes.
Will my pet also need blood tests?
Often, yes.
Blood tests and urinalysis provide complementary information and are frequently performed together to obtain the most complete picture of your pet’s health.
