How to use the AZO Urinary Tract Infection (UTI) Test


Experiencing symptoms of a urinary tract infection (UTI) can be both uncomfortable and worrying. Fortunately, with tools like the AZO UTI Test, you can quickly check for signs of a UTI from the comfort of your home.

This easy-to-use test can help you determine whether it’s time to visit a healthcare professional.

In this blog, we’ll guide you through the straightforward steps of using the AZO UTI Test, ensuring you can perform the test confidently and correctly.

What is a UTI?

A Urinary Tract Infection (UTI) is an infection in any part of the urinary system, which includes the kidneys, ureters, bladder, and urethra. Most infections involve the lower urinary tract — the bladder and the urethra.

Women are at greater risk of developing a UTI than men, due to their shorter urethra, which makes it easier for bacteria to enter the bladder and cause infections.

While UTIs are typically treatable, it’s essential to diagnose and address them early to prevent complications.

Common Symptoms of UTI

Identifying the symptoms of a UTI early is crucial for effective treatment.

Common symptoms include:

  • A strong, persistent urge to urinate
  • A burning sensation when urinating
  • Passing frequent, small amounts of urine
  • Urine that appears cloudy
  • Urine that appears red, bright pink, or cola-colored — a sign of blood in the urine
  • Strong-smelling urine
  • Pelvic pain, especially in women, in the center of the pelvis and around the area of the pubic bone

It’s important to note that symptoms can vary depending on the severity and the specific part of the urinary tract that’s infected. If you experience any of these symptoms, using a test like the AZO UTI Test can be a helpful first step in identifying if a UTI is the cause.

About the AZO UTI Test

The AZO UTI Test is an over-the-counter diagnostic tool that can be used at home to screen for signs of a urinary tract infection. This test works by detecting the presence of nitrites and leukocytes (white blood cells) in the urine – both of which can indicate an infection.

The test strips are easy to use and come with instructions that guide you through the process. Simply dip the test strip into a sample of your urine, and compare the color change to the chart provided.

This offers a quick, initial indication of whether you might have a UTI, but it’s important to consult with a healthcare provider for a definitive diagnosis and appropriate treatment.

Benefits of using the AZO UTI Test

Using the AZO UTI Test offers several benefits:

  • Convenience: The test can be performed in the privacy of your own home.
  • Speed: Results are available in just a few minutes, which means you can take appropriate steps faster if you suspect a UTI.
  • Ease of Use: The test strips are designed to be easy to use, with simple instructions and a clear reading chart.
  • Early Detection: Early detection can lead to timely treatment, potentially averting more serious complications.

This test is particularly beneficial for individuals who have recurrent UTIs and need to monitor their condition regularly. However, while the AZO UTI Test can be a great tool for screening, it’s important to remember that a positive result should always be followed up with a consultation from a healthcare professional to confirm the infection and discuss treatment options.

How to Use the AZO UTI Test

Before you start the AZO UTI Test, it’s crucial to prepare properly to ensure the accuracy of the results.

First, read the instructions carefully to familiarize yourself with the process. Make sure you have a timer on hand, or use PURI Apps’s built in timer, as timing plays a crucial role in the test’s accuracy. It’s also important to use the test first thing in the morning, when your urine is most concentrated. Avoid drinking excessive fluids before the test to prevent dilution of your urine, which can affect the results. Wash your hands thoroughly and ensure the area is clean to prevent contamination.

Now that you’re prepared, let’s walk through the testing process:

1. Remove the Test StripOpen the foil pouch and immediately remove one test strip. Close the pouch tightly to protect any remaining strips from moisture.
2. Conduct the TestEither urinate directly on the test strip pad or dip it into a clean container of urine for about 1 to 2 seconds until both test pads are fully saturated.
3. Wait for ResultsLay the strip flat on a non-absorbent surface and start the timer. Wait exactly 2 minutes. Avoid moving the strip during this time to ensure the test pads are not disturbed.
4. Read the resultsAfter two minutes, the test is complete, and it is time to read the results.

Interpreting the Results

Once you’ve waited the necessary two minutes, compare the colors on the test strip to the color chart included in the test kit:

  • Normal/Negative: If the color matches the negative control, no leukocytes or nitrites were detected.
  • Positive for Nitrites: A pink or red color indicates the presence of nitrites, which could suggest a bacterial infection.
  • Positive for Leukocytes: A purple color indicates the presence of white blood cells (leukocytes).

If either or both fields show a positive result, it’s advisable to contact your healthcare provider for further analysis and possible treatment.

Best Practices for Accurate Results

For the most reliable results from your AZO UTI Test, consider the following best practices:

Best PracticeReason
Test Early in the DayUse your first morning urine for the highest concentration of bacteria.
Follow Instructions CarefullyDeviations from the instructions can alter the results.
Store Properly Keep unused strips in their sealed pouch at room temperature, away from moisture and heat.
Check Expiry Date Expired tests might not provide accurate results. Always check the expiry date on the package before testing.

Understanding False Positives and Negatives

While the AZO UTI Test is a helpful tool, it’s important to understand its limitations, including the possibility of false positives and false negatives:

False PositiveUse of medication , high vitamin C intake, or menstruation.
False NegativeDiluted urine, which can occur if you consume a lot of fluids before the test.

If your results are positive or if you have symptoms despite a negative result, visiting a healthcare provider is key. They can perform more comprehensive tests and offer appropriate treatments tailored to your condition.

Home Testing vs. Lab Testing

When it comes to detecting a urinary tract infection (UTI), the two main avenues are home testing, like using the AZO UTI Test, and lab testing, typically done at a medical facility.

Home testing offers privacy and immediacy. You can perform the test discreetly at your convenience and have results within minutes. This immediacy can be crucial for starting treatment early and managing symptoms quickly. However, while home tests can indicate whether you might have a UTI, they aren’t as thorough as lab tests, which analyze urine for a variety of markers and can identify the specific bacteria causing the infection.

Lab tests, on the other hand, while being more detailed, require a visit to a healthcare provider and take longer to return results. This could be a setback if you are seeking immediate relief from painful symptoms. Moreover, lab tests can be more expensive than home tests, depending on insurance coverage and lab fees.

Deciding between the two often depends on the severity of symptoms and whether you need a definitive diagnosis for specific treatment.

Pros and Cons of the AZO UTI Test

The AZO UTI Test strips are an excellent tool for a quick screening at the first sign of UTI symptoms. One of the biggest advantages of the AZO UTI Test is the convenience factor. It can be done at home and takes only a few minutes to yield results. Furthermore, it’s relatively cost-effective compared to a doctor’s visit and lab work.

However, there are drawbacks to consider. The AZO UTI Test, while useful for indicating the presence of an infection, does not identify the type of bacteria involved or the severity of the infection. This can be critical because different bacteria may require different antibiotics.

There’s also the chance of a false positive or negative result, meaning the test might indicate a UTI when there isn’t one, or vice versa, which could lead to unnecessary anxiety or delayed treatment.

FAQs about the AZO UTI Test

Q: How accurate is the AZO UTI Test?

A: The AZO UTI Test is designed to detect nitrite and the presence of white blood cells (leukocytes) which are common indicators of UTI. While generally reliable, like all medical tests, there can be cases of false positives or negatives.

Q: Can I use the AZO UTI Test during menstruation?

A: It is recommended to avoid using the AZO UTI test during menstruation as blood can interfere with the result, leading to inaccurate readings.

Q: How often can I use the AZO UTI Test?

A: You can use the AZO UTI Test as needed to check for the presence of a UTI, especially if symptoms appear. However, it’s crucial to consult with a healthcare provider if symptoms persist or worsen, regardless of the test results.

Troubleshooting Tips

Using the AZO UTI Test is typically straightforward, but here are a few tips to ensure you get the most accurate results:

  • Ensure your hands and the testing area are clean to avoid contaminating the test strip.
  • Follow the instructions carefully, particularly the timing, as leaving the test strip in the urine too long or not long enough can skew results.
  • Store the test strips in a cool, dry place. Exposure to moisture and heat can degrade them, potentially leading to incorrect outcomes.
  • If you get a positive result, follow up with your healthcare provider for further testing and appropriate treatment. If the test result is negative but you still experience symptoms, it’s also a good idea to consult a professional, as not all UTIs may produce detectable levels of nitrites or leukocytes early on.

By taking these steps, you can more reliably use the AZO UTI Test as a helpful tool in managing urinary health.


Navigating the discomfort of UTI symptoms can be distressing, but with the AZO UTI Test, you can quickly take a proactive step in determining your health status from the comfort of your home. It offers a reliable way to indicate if a visit to the healthcare provider is necessary. Remember to follow up with a medical professional for diagnosis and appropriate treatment as the test is not a substitute for professional medical advice. Stay vigilant about your health and don’t hesitate to consult with a healthcare provider if you’re experiencing any troubling symptoms.
