This test measures three critical parameters: Specific Gravity, Protein, and Creatinine. Specific Gravity indicates how well your pet's kidneys are concentrating urine; consistently dilute urine is often one of the first signs of renal failure. Protein detection checks for proteinuria, which occurs when damaged kidneys leak protein from the blood into the urine.

Creatinine is a waste product excreted by the kidneys at a relatively constant rate. By measuring both protein and creatinine, you can calculate the Urine Protein:Creatinine (UP/C) ratio. This ratio provides a much more accurate assessment of kidney health than measuring protein alone, as it accounts for how dilute or concentrated the urine sample is.

These are the exact same parameters your vet would check during a standard urinalysis. Monitoring them at home allows you to track changes over time, which is especially useful for senior pets.

It is crucial to use specifically calibrated animal urinalysis strips because the normal baseline parameters for dogs and cats differ significantly from those of humans. For example, the specific gravity of healthy feline urine is naturally much more concentrated than human urine, so a human test strip would likely yield inaccurate or misleading results.

Additionally, the threshold for what constitutes abnormal protein levels varies between species. Using a human test could result in a false positive, causing unnecessary worry, or a false negative, meaning you might miss early signs of chronic kidney disease (CKD) when intervention is most effective.

These ONE STEP strips are designed exclusively for veterinary use, ensuring the chemical pads react appropriately to the unique composition of cat and dog urine. This guarantees that the results you read against the colour chart are accurate and reliable for your pet.

One of the earliest and most common signs of chronic kidney disease (CKD) in both dogs and cats is polydipsia (increased thirst) accompanied by polyuria (increased urination). You might notice your pet drinking from their bowl more frequently, seeking out unusual water sources, or needing to go outside more often. Cats may start leaving larger, heavier clumps in their litter tray.

As the disease progresses and the kidneys lose their ability to filter toxins, you may observe a decrease in appetite, unexplained weight loss, and lethargy. Your pet might also experience vomiting, diarrhoea, or develop a dull, unkempt coat. In advanced stages, they may suffer from bad breath with a chemical or ammonia-like odour due to the build-up of urea in the bloodstream.

Because animals instinctively hide illness, these symptoms often don't become obvious until up to 75% of kidney function has already been lost. This is why proactive screening with urine test strips is so valuable for older pets. Similar to how we monitor our own health, early detection is key to managing chronic conditions effectively.

Collecting a urine sample requires a bit of patience, but it is entirely non-invasive. For dogs, the easiest method is to take them out on a lead. When they lift their leg or squat, gently slide a clean, shallow container (like a washed takeaway tub or a specialised urine collection ladle) into the urine stream. Try to catch the 'mid-stream' sample, as this is less likely to be contaminated by bacteria from the lower urethra.

For cats, collection can be slightly trickier. The most effective approach is to empty their litter tray completely, clean it thoroughly, and replace their normal litter with a non-absorbent alternative. You can purchase special hydrophobic veterinary litter (often plastic beads), or use clean aquarium gravel. Once the cat has urinated, you can easily pour or pipette the liquid into a clean container.

It is important to test the urine as soon as possible after collection—ideally within 30 minutes. If you cannot test it immediately, store the sample in the refrigerator, but ensure you allow it to return to room temperature before dipping the test strip, as cold urine can affect the chemical reactions on the pads.

The Urine Protein:Creatinine (UP/C) ratio is a simple calculation that helps determine if protein loss in the urine is clinically significant. To calculate it, you first read the protein result from the test strip and note the corresponding numerical value from the colour chart. Next, you read the creatinine result and note its numerical value.

You then divide the protein value by the creatinine value. For example, if the protein pad shows 30 mg/dL and the creatinine pad shows 100 mg/dL, the UP/C ratio is 30 ÷ 100 = 0.3. The kit includes detailed guidance on how to interpret this final number, as the thresholds for concern differ slightly between dogs and cats.

Generally, a UP/C ratio of less than 0.2 in cats and 0.4 in dogs is considered normal. Values above these thresholds indicate proteinuria, which warrants veterinary investigation. By using the ratio, you account for the urine's concentration—a trace amount of protein in very dilute urine is far more concerning than the same amount in highly concentrated urine.

If the test strip indicates low specific gravity (dilute urine), high protein, or an elevated UP/C ratio, your first step should be to contact your veterinarian to schedule an appointment. Do not panic, as abnormal results can sometimes be caused by temporary issues like a urinary tract infection (UTI) rather than chronic kidney disease.

Take a clear photograph of the test strip next to the colour chart immediately after the 60-second reading time, and show this to your vet. They will likely want to perform a comprehensive blood panel to check Blood Urea Nitrogen (BUN) and SDMA levels, alongside a laboratory urinalysis to confirm the diagnosis and assess the exact stage of any renal dysfunction.

If kidney disease is diagnosed, your vet will recommend a management plan. This typically involves transitioning your pet to a prescription renal diet that is restricted in phosphorus and high-quality protein, which significantly reduces the workload on the kidneys. They may also prescribe medications to manage blood pressure or protein loss, and advise on strategies to increase your pet's water intake.

For healthy adult dogs and cats under the age of 7, testing their urine once a year as part of an annual health review is usually sufficient. This establishes a baseline for their specific gravity and protein levels, making it easier to spot subtle changes later in life.

Once your pet reaches their senior years (typically around 7 or 8 years old, depending on the breed), the risk of chronic kidney disease increases significantly. For these older pets, testing every 3 to 6 months is recommended. Proactive monitoring is the best way to catch renal decline in its early, silent stages before clinical symptoms like weight loss and lethargy appear.

If your pet has already been diagnosed with early-stage kidney disease, or if they are on medications that can affect renal function (such as certain NSAIDs for arthritis), your vet may suggest testing more frequently. Regular home testing allows you to track the effectiveness of dietary changes and medications without the stress and expense of frequent clinic visits.

Yes, your pet's diet and water intake can significantly influence the results of a urinalysis, particularly the specific gravity and protein readings. A diet very high in protein can sometimes cause a temporary, mild increase in urinary protein excretion. Conversely, if your pet has recently consumed a large volume of water, their urine will naturally be more dilute, resulting in a lower specific gravity reading.

To obtain the most accurate and consistent results, it is best to test the first urine passed in the morning. This 'first morning void' is typically the most concentrated sample of the day, making it the most reliable indicator of the kidneys' true concentrating ability and the best sample for detecting abnormal protein leakage.

If you have recently changed your pet's diet, especially to a prescription renal or urinary formula, you should wait a few weeks before testing to allow their system to adjust. Always ensure your pet has access to fresh water, but try to maintain their normal routine prior to collecting a sample to avoid artificially skewing the results.

Absolutely. While these strips are excellent for early detection, they are equally valuable for monitoring pets that have already been diagnosed with chronic kidney disease (CKD). Regular home testing allows you to track the progression of the disease and the effectiveness of your management strategy in a stress-free environment.

By monitoring the UP/C ratio and specific gravity every few weeks, you can quickly identify if protein loss is worsening or if the kidneys are losing further concentrating ability. This real-time data empowers you to have more informed discussions with your vet, potentially allowing for timely adjustments to medications or diet before a crisis occurs.

Home monitoring is particularly beneficial for cats, who often find trips to the vet highly stressful. Stress can temporarily alter physiological parameters, so testing at home often yields a more accurate reflection of your pet's day-to-day baseline.
