    Sweet Cures urine test strips are quick and easy to use to detect 5 main elements (leukocytes, nitrites, proteins, pH, blood) and know exactly what is happening in your urine. You can manage their pH, check them for the presence of nitrites or an infection, and monitor their evolution. An information sheet is included, but you should consult your doctor or urologist to interpret the results.

    How to use urine test strips

    UTItest 5V is suitable not only for healthcare professionals who perform tests, but also for individuals. We therefore include a very simple guide for people who have no technical knowledge, as well as a complete medical information brochure for professionals who master the technical details.

    Precise instructions can be found in the box

    The test strips quickly and easily indicate the infection status of your urine. Consult your doctor or urologist for a detailed interpretation of your results.

    1. Urinate in a clean container.
    2. Take out a test strip and close the box tightly. Dip the strip into the urine for 2 seconds. Tap the side of the strip on the edge of the container to remove excess urine. If the excess urine is transferred from one reagent to another on the test strip, the results will be incorrect.
    3. Observe the reagent strips on the test strip. The first thing to check (after 20 to 30 seconds) is the pH, on the 2nd strip from the bottom.

    a/ If the reagent has turned orange, the urine is too acidic.

    b/ If it has turned dark green, the urine is too alkaline.

    You can balance your urinary pH through your diet. Consult a dietician.

    1. Check the proteins (in the middle). A turquoise-green hue is a sign of protein. The darker the shade, the more protein. This usually means that your kidneys are suffering from an infection. Check with your doctor for advice.
    2. Check the red blood cells. A green colour indicates blood. If the reagent turns dark green within 60 seconds, there is a lot of blood in your urine. There can be many reasons for this, so do not be overly concerned and consult your doctor.
    3. Check for nitrite (2nd band from top). Nitrates are broken down into nitrite by bacteria, so a pink colour indicates the presence of bacteria in your urine.
    4. Check the last reagent (top) for leukocytes (white blood cells). A pink stain appearing within 2 minutes indicates the presence of inflammation and possibly bacteria.

    The more intense the colouring becomes in the time period indicated, the more certain it is that bacteria are present and the more concentrated they are. To have your urine tested to obtain detailed information about the bacterial strain and possible kidney damage, or for a better interpretation of the test results, consult your doctor or a specialist.

    Other points for consideration

    While monitoring the quality of your urine is important to interpret your progress, it is not enough. UTItest 5V can tell you with a high degree of reliability whether you still have a urinary tract infection, but it cannot define the strain of bacteria involved. If natural remedies are unable to cure the infection, have a culture taken from your urine by a competent laboratory to identify infectious agents.

    Advantages of the urine test

    • A simple home test. Boxes of 50 strips allow repeated testing over a long period of time.
    • A quick check of the pH of your urine. A pH of 7.5 to 8 (alkaline) in most cases contributes to slow bacterial growth and helps prevent infections. Our grandmothers knew this and used to drink barleyat with lemon juice to promote an alkaline environment that was not welcoming to most bacteria that cause urinary tract infections.
    • Checking blood cells, proteins and nitrites. The presence of red and white blood cells indicates inflammation or infection. Protein indicates possible kidney infection. Normally, nitrites are only detected in urine in the presence of bacteria.
    • The guarantee of good medical reliability.
    • Simple instructions for home use.
    • A diagnostic aid appreciated by Sweet Cures customers for years. We have sold thousands of test kits and have always had excellent feedback on their effectiveness and ease of use compared to other brands.
    • Receipt of the shipment usually the next day.
    • The help of a very efficient customer service, with ten years of experience.

    Principles and limitations of urine testing


    The test reveals the presence of glanulocytic esterases. These esterases cleave an indoxyl ester, and the indoxyl released reacts with a diazonium salt to produce a purple dye.

    The resulting leukocyte esterase may be positive in the absence of observable cells if the leukocytes have lysed. Positive results can sometimes be found in random urine samples taken from women. They are due to contamination of these samples by vaginal discharge. High glucose concentrations (55-110 mmol/l) or high specific gravity may decrease the intensity of the result. The presence of cephalexin, cefalotin or tetracycline may cause a decrease in reactivity, and high levels of these drugs may cause a false negative reaction. The reactive zone does not react with lymphocytes.


    The test is based on the principle of the Griess test, which is specific for nitrites. All degrees of uniform pink should be interpreted as positive.

    Positive test results suggest the presence of 105 (100,000) or more organisms per ml of urine, but colour development is not proportional to the number of bacteria present. A negative result in itself does not prove that there is no significant bacteriuria. Negative results may occur when urinary tract infections are caused by organisms that do not contain reductase to convert nitrate to nitrite; when urine has not been retained long enough in the bladder (4-8 hours) for nitrate reduction to occur; or when nitrate is absent from the diet, even if organisms containing reductase are present and incubation in the bladder is sufficient. Ascorbic acid concentrations of 2.8 mmol/l or higher may cause false negative results in samples containing a nitrite ion concentration of 35 μmol/l or less.

    Protein :

    The test is based on the protein error principle of pH indicators.

    The reactive zone is sensitive to albumin. A high pH (greater than 9) may affect the test. Residues of disinfectant containing quaternary ammonium groups or chlorhexidine in the urine collection container may cause a false positive result.

    pH :

    This test contains a mixed indicator that causes a marked change in colour between pH 5 and pH 8.5. It may be necessary to repeat the test several times at intervals of 3 hours to determine the dominant pH. High or low pH, or sudden pH changes may indicate the presence of bacteriuria.


    Hemoglobin and myoglobin catalyze the oxidation of the indicator by means of the organic hydroperoxide in the test strip.

    This test is very sensitive to haemoglobin and can complement the microscopic examination. The sensitivity of this test can be reduced in urine with a high specific gravity (very concentrated). The test is also sensitive to myoglobin and hemoglobin (a hemoglobin concentration of 150-620 μg/l is approximately equivalent to 5-15 intact red blood cells per microliter). Captopril and iodine may also decrease reactivity. Blood is often found in the urine of menstruating women. Some oxidizing contaminants such as hypochlorite can promote false positive results. The presence of microbial peroxidase associated with a urinary tract infection can also lead to a false positive result. Ascorbic acid concentrations of 2 mmol/l or more can cause false negative trace results.

    Values and scope

    The values depend on the presence or absence of interfering samples.


    Tests Reference values Scope

    Leukocytes Granulocytes: 15-40 /μl Negative - 500 cel./μl

    Nitrites 13-22 μmol/l Negative - positive

    Proteins Albumin: 0.10-0.15 g/l Negative - 5 g/l

    pH Unit: 0.5 pH pH from 5 to 8.5

    Blood Hemoglobin: 0.15-0.60 mg/l Negative - 200 cel./μl


    Reagent composition

    Based on the dry weight content of each reagent per 100 strips:

    Leukocytes: 1.4 mg indoxyl ester, 0.7 mg diazonium salt

    Nitrite: 0.65 mg sulfanilamide, 0.45 mg Naphthyl ethylenediamine dihydrochloride

    Protein: 0.36 mg Tetrabromophenol Blue

    pH: 0.06 mg methyl red and 1.3 mg bromothymol blue

    Blood: 35.2 mg cumene hydroperoxide, 3.3', 5.5' and 15 mg tetramethylbenzidine


    1. Handling: Use a clean container to collect urine. For blood, false positive readings may result from the presence of strongly oxidizing disinfectant residues in the sample collection container. Do not add preservatives to the urine to be tested.
    2. Operation: Incorrect results may be obtained when the strip is stirred in the container. Soak for approximately 2 seconds. If the immersion time is too short or too long, the result may be impossible to interpret.

    Sample Collection and Preparation

    Collect the urine in a container and test as soon as possible. Do not centrifuge. The use of urine preservatives is not recommended. If the test cannot be performed within one hour after urination, refrigerate the sample immediately. Allow the sample to return to room temperature before testing.

    Test procedure

    1. Take a strip from the bottle and close the cap tightly.
    2. Immerse all test areas of the strip in fresh, well-mixed urine. Remove the strip immediately to prevent the reagents from dissolving in the urine.
    3. When removing it, tap the side of the strip on the edge of the container to remove excess urine. Dry its profile on absorbent paper. Avoid rubbing the surface of the strip (the reagents may become contaminated with each other).
    4. Compare each reagent area to the corresponding color blocks on the color chart and read them off within the specified time. Adherence to the reading time is essential for good results.
    5. View your results by direct comparison with the colours on the map.

    NOTE: All reagent areas will be read within 1 to 2 minutes to distinguish a positive from a negative specimen. Color changes after 2 minutes have no diagnostic value.

    Quality control

    For good results, the performance of the test strips will be confirmed by comparing them with known negative and positive samples or controls. This procedure is recommended after 25 test strip uses and at each box and lot change. Users and laboratories should establish their own standards for performance standards.


    The results are obtained by direct comparison with the colours of the card printed on the container label. The colour card shows the nominal values. The actual values will vary around the nominal values.


    Inadequate storage may reduce the performance of the test strips. Allow them to return to room temperature before use. Do not use damaged, discolored, or blackened test strips. Avoid contamination with volatile chemicals. Do not touch the test strip test papers.

    Please Note

    In principle, diagnosis or treatment is not based solely on the result of a single test, but must be established in the context of all other medical elements. Knowledge of the effect of drugs or their metabolites on individual tests is not yet complete. In case of doubt, it is preferable to repeat the test after discontinuation of a given drug. Large amounts of ascorbic acid in the urine can artificially produce false negative results, more or less low, for the presence of blood or nitrite in the urine.


    Store the strips at a temperature of 3 to 30°C, away from moisture, direct light, and heat. Keep them in their original bottle. Leave the desiccants in the bottle. Do not take a strip out of the bottle unless you use it right away. Replace the cap tightly and immediately after removing the test strip. Unused strips in a closed bottle should be used within 3 months. Do not use the test strips after the expiration date printed on the label.

    Food supplements should be used as part of a healthy lifestyle and a varied and balanced diet.

    Strips for urine testing

    Product corresponding to my expectations, easy to use, the results seem valid, the only problem is the manual which is not in French.

    s.k. (Sierentz, FR)
    quick and accurate

    I've been using these strips for prevention since I had a UTI in 2019.
    I was able to establish a good correlation with the lab results.
    and since I use them every 2 weeks, the results reassure me and confirm some feeding drifts, especially the pH.
