How to Read UTI Test Strips – A Friendly Guide

How to read UTI test strips - Understand the color codes and patterns on dipstick tests for accurate urinary tract infection diagnosis.

A UTI can make your bladder feel like it’s under attack. Going to the bathroom is usually a relief from work, emails, or kids. But with a UTI, you feel the constant need to go, and it burns when you do. It’s hard to know if it’s a UTI right away. Imagine if an infection changed your pee to purple! Sadly, that’s not how UTIs work. They can be tricky to spot, often feeling like other problems. That’s where UTI Test Strips from Uqora come in. They’re a simple way to check for a UTI at home.1

Key Takeaways

  • UTI Test Strips from Uqora are an at-home diagnostic tool that can detect substances in the urine commonly associated with UTIs.
  • Research indicates a 98% sensitivity for UTI detection using Uqora UTI Test Strips, which detect both nitrites and leukocyte esterase.1
  • The test strips can indicate the presence and abundance of white blood cells (leukocyte esterase) and nitrites in the urine, which are markers of a potential UTI.
  • Interpreting the color changes on the test strip can provide valuable insights into the likelihood of a UTI, but medical consultation is still recommended for proper diagnosis and treatment.
  • Proper sample collection and handling is crucial for accurate test results.

Understanding UTI Test Strips

Urinalysis is a test that checks a urine sample for health issues. It looks at many things to check the patient’s health. Urine test strips help find problems like kidney disease, UTI, and diabetes. These rapid test strips easily show if something in the urine is not right. They give results fast, which is why they are popular for checking urine.

What are UTI Test Strips?

UTI Test Strips detect Leukocyte esterase and Nitrites in urine.1 Leukocyte esterase comes from white blood cells being broken down. White blood cells help fight infections, so they often show a UTI.1 Nitrites form when certain bacteria change urea, a type of waste.1

Benefits of Using UTI Test Strips

1Studies say UTI Test Strips are 98% successful when they find nitrites and LE. This makes them good for testing at home.1 They help people know about their health at home. But, it’s still smart to see a doctor even if the test is negative.1

Preparing for the UTI Test

It’s crucial for health workers and caregivers to know how to read a urine test strip correctly. They must understand the result’s meaning. For a urinalysis test, use a fresh mid-stream urine sample.2 Start by urinating a little into the toilet, then collect your sample. If the sample will be over 2 hours old at test time, keep it in the fridge.2 When a sample is open to the air too long or left at room temperature, get a new one.2 Keep in mind that urine samples are easily contaminated by outside bacteria. Always take care when collecting and handling them. Use a sterile urine kit, like a Urine A & B Sample Kit.2

Gathering Supplies

Before you start the test, wash your hands well with soap and water.2 This step lowers the risk of getting incorrect results due to contamination.

Proper Hand Hygiene

Good hand hygienefor uti test> is key when getting ready for a urine sample collectioncollection>. Be sure to wash your hands advanced to keep out bacteria. This helps ensure your test results are accurate.

Collecting the Urine Sample

To start, urinalysis tests need a fresh mid-stream urine sample.2 The patient should first pee for a few seconds, not in the sample container.2 After collecting, if testing takes over 2 hours, keep the sample cold.2 Any sample left in the air or not refrigerated for long is no good. You should get a new one to test properly.2 Be careful not to let the sample touch anything before you collect it. Using a sterile urine collection kit, like a Urine A & B Sample Kit, is best.

Midstream Urine Collection

For a mid-stream sample, start by peeing into the toilet. Then let your urine flow into the collection container.2 This method avoids bacteria that might be at the start or end of the stream.

Handling the Sample Properly

After collecting the urine, it’s important to prevent it from getting contaminated.2 Test the sample quickly. If you can’t test it within 2 hours, store it in the fridge.2 This protects the sample from bacteria growth. Testing the sample soon and handling it right are key to getting correct test results from the urine strips.

Dipping the Test Strip

Always read the manufacturer’s instructions first. They might differ a bit from kit to kit.2 Before testing, lightly swirl the container to mix the urine sample. To start, hold the end of the strip with the rough side. Dip it into the urine so that every reagent pad is in the sample. Immediately take the strip out. Let extra urine drip off the strip’s edge, not down the test area.

Timing is Key

The colors can start to change in about 30 seconds. But, sometimes, it takes up to two minutes for the results.1

Avoiding Contamination

2 For accurate results, collect your urine sample mid-stream. If you’ll test it more than 2 hours later, keep it in the fridge. A sample that’s been out too long or exposed to air should not be used. It could have bacteria that contaminate the test. Always be careful in collecting and handling the urine.

Interpreting the Results

Compare the test strip to the color chart to see the changes. Different urine test strips need special reading steps, so check the instructions first. If new colors appear after a few minutes, ignore them. The longer urine sits on the strip, the more likely it is to show a wrong result.1

Understanding the Color Codes

The Uqora UTI Test Strip’s first line shows if white blood cells (WBC’s) are in the urine. It changes from white to pink if WBC’s are found. White means no WBC’s, and bright pink means lots of WBC’s.1 The second line checks for nitrites, changing color from white to purple. No color means no nitrites, and deep purple means there are nitrites.1

Leukocyte Esterase (LE)

LE is a signal of white blood cells breaking down. These cells are linked with fighting infections, often found in a UTI.1


Nitrites form when bacteria break down a type of waste. Knowing about both LE and nitrites gives UTI tests a high accuracy, at 98%. This makes the Uqora test strips a reliable choice for home testing.1

Reading the Test Strip

If both pads on the Uqora UTI Test Strip are purple, a UTI is likely.1 This means the body is fighting an infection if leukocyte esterase (LE) is found in the urine.1 A negative nitrite result doesn’t rule out a UTI. But, it might mean the UTI is not severe.1

Positive for LE and Nitrites

Both LE and nitrite pads turning color suggests a UTI is likely.1 These results need a doctor’s check and might need treatment.1

Positive for LE, Negative for Nitrites

If the LE pad changes color, signaling white blood cells, a UTI might be detected.1 Then, consulting a doctor for further tests or treatment is wise.1

Negative for Both LE and Nitrites

No color changes in LE or nitrite pads means a UTI is less likely.1 But, if UTI symptoms are there, talking to a doctor is still vital. It’s important to retest since a negative doesn’t always mean no infection.1

how to read uti test strips

Urine test strips are quick and simple indicators of your urine’s infection condition.1 For detailed advice, see a doctor or urologist. First, pee into a clean container.

Next, remove a strip from its container. Close the container tightly. Dip the strip in urine for 2 seconds. After that, tap it on the container’s side to get rid of extra drops. Then, observe the reagent patches.

First, look at the pH, which is the second from the bottom. Then, check the Protein (middle). After that, observe for Blood (bottom). Next, look for Nitrites, the second one from the top.2 Finally, check for Leukocytes (white blood cells) at the very top.1 If there’s more color after 20 to 30 seconds, it might mean more bacteria and at higher levels.

Factors Affecting Test Accuracy

Using urinalysis test strips correctly is key to better results. False positive results might be more common than false negatives.3 A high level of ascorbic acid in the urine can skew urine dipstick tests. This can happen with people who take a lot of vitamin C. They might get false negative results.3

Dietary Factors

Not getting enough nitrates in your diet can hide nitrites in the urine.3


AZO, a common drug, can change test results by affecting urine color.3

Timing of the Test

Nitrite detection is best if the urine sits in the bladder for about 4 hours.3 But, nitrite test strips can also be influenced by air exposure or urine color from some over-the-counter UTI treatments.3

When to Consult a Healthcare Provider

If you see a small result on a UTI test strip, tell your doctor right away.4 It’s crucial to get treatment early if there are UTI symptoms. Remember that a negative result might still mean you have an infection.4 Test strips aren’t perfect. They check for certain things in your urine. But sometimes, other tests are needed too, like rapid tests. These quick tests can help your doctor decide on the best treatment when combined with other information.

When you suspect a UTI, getting medical advice is key.4 It helps stop the infection from spreading and lowers the chance for problems later. Doctors might ask about your symptoms, if you’ve had UTIs before, your health history, and more.5 You can also ask when you should start feeling better and what to do if you don’t. They’ll talk to you about treatment and how to prevent future UTIs.

6 Common UTI signs are pain or a burning feeling when you pee, needing to pee often and right away, pelvic pain, wetting the bed at night, and urine with blood.6 Having 3 or more UTIs in a year, or 2 in 6 months, is called recurrent UTIs.6 Most UTIs are because of E. coli bacteria, but others can cause them too, like fungi and viruses.

5 Sometimes, a doctor will treat a suspected UTI without a test. But, if they need to be sure, you will provide a urine sample.5 This sample might be quickly checked with a dipstick or sent to a lab for detailed testing. Lab results may take a few days.

Maintaining Urinary Tract Health

To keep your urinary tract healthy and avoid UTIs, follow these steps. First, focus on staying hydrated. Then, consider making dietary adjustments. Last, pay attention to practicing good hygiene.

Staying Hydrated

Drinking plenty of water is key for a healthy urinary tract. More water flushes out bacteria. It also helps maintain a clean urinary tract. Trust the UTI test strip – the less colored, the better.

Dietary Considerations

Your diet affects your urine’s acidity. Talk to a dietitian to make your urine more alkaline. This can make it harder for bacteria to thrive.1 Eating foods high in vitamin C, like citrus fruits, also supports your urinary tract.4

Hygiene Practices

Good personal hygiene is crucial. Always wipe from front to back after using the bathroom. This stops bacteria from getting into the urinary tract.4 Choose loose, comfortable clothes and avoid tight underwear. This helps keep your urinary tract healthy.4

By staying hydrated, watching your diet, and keeping clean, you can maintain urinary tract health. This lowers your risk of getting UTIs. For any questions or more advice, talk to your healthcare provider.1,4,7

The results show quickly, which is good when waiting for other results. If you doubt a result, test again with fresh urine.1

If you show UTI symptoms but the test is negative, it doesn’t mean you don’t have a UTI. In this case, a urine culture is needed to be sure.1

Combining UTI Test Strips with Other Diagnostic Tools

Checking your urine’s health can show how you’re doing. But it might not show everything. While UTI Test 5V® reliably checks for ongoing infections, it can’t specify the bacteria type.1 If home treatments don’t work, ask a clinic to test your urine and find the exact infection type.10

Urine Culture

A urine culture lab test pinpoints the bacteria behind a UTI. It also figures out the best antibiotics to treat it. This test complements UTI test strips by giving deeper information.1

Physical Examination

Aside from UTI test strips, a doctor’s check-up is key.10 They look for signs like pain and tenderness. These signs help tell what the infection is and how bad it is.

Using UTI test strips along with urine culture and check-ups is best.110 It gives you and your healthcare team a full view to plan the right treatment.
