UTI test kit at home is a qualitative IVD self-test that detects leukocytes, blood, nitrite and protein in urine. All four test areas are read after 2 minutes using the supplied colour chart. The test can provide an initial indication of changes in the urine, but it cannot by itself confirm or rule out a urinary tract infection.
Why choose this UTI test kit at home?
This at-home UTI test kit checks four different urine parameters from the same sample. It therefore provides information from several test areas instead of checking only one parameter such as nitrite.
- leukocytes, blood, nitrite and protein on one test strip
- results read after 2 minutes
- simple urine sample
- supplied colour chart for visual interpretation
- CE 0123-marked IVD self-test for home use
What does the four-parameter UTI test check?
The test qualitatively detects four parameters in urine: leukocytes, blood, nitrite and protein.
Leukocytes are white blood cells that may be present in increased amounts when inflammation is present in the urinary tract.
Blood may produce a reaction on the test area. Blood in urine can have several different causes and is not specific to a urinary tract infection.
Nitrite may be produced when certain Gram-negative bacteria convert nitrate in urine into nitrite. However, not all bacteria associated with urinary tract infections produce nitrite.
Protein is detected by a colour change on the test area. Protein can also be present in urine for reasons other than a urinary tract infection.
The test does not identify the microorganism responsible for a possible infection and does not determine the cause of an abnormal result.
Who is this UTI self-test for and when should it be used?
The test is intended for self-testing when you want to check leukocytes, blood, nitrite and protein in urine as an initial assessment at home.
The manufacturer recommends using urine collected early in the morning because it is generally most concentrated at that time.
If symptoms are severe, continue despite a negative result or your general condition worsens, contact a healthcare professional.
What should you consider before taking the test?
For women, the manufacturer states that the test should not be performed during menstruation or within three days after menstruation has ended. The urine sample should not be contaminated with vaginal discharge.
For the nitrite result, the urine should have remained in the bladder long enough. According to the manufacturer, a bladder time of less than 4 hours may result in a negative nitrite result even when bacteria are present.
The results may also be affected by antibiotic treatment, ascorbic acid or vitamin C, certain medicines, high urine specific gravity, alkaline urine and substances that strongly alter urine colour. Lighting conditions and colour vision may also affect visual interpretation.
How to use the UTI test kit at home
- Collect urine in the supplied plastic cup or another clean container without detergent or disinfectant residue.
- Open the foil pouch and remove the test strip without touching the reagent areas.
- Immerse all four test areas in the urine sample for approximately 1–2 seconds.
- Remove the strip and wipe off excess urine against the edge of the container or on absorbent material.
- Wait 2 minutes and compare each test area with the supplied colour chart.
Do not interpret the result after 3 minutes. Always follow the instructions for use supplied with the test.
How are leukocytes, blood, nitrite and protein interpreted?
Each test area is interpreted separately by comparing its colour with the corresponding colour scale.
Leukocytes: a purple colour change indicates that leukocytes have been detected in the urine.
Blood: a green colour or green spots may indicate the presence of blood.
Nitrite: an even pink-to-red colour indicates the presence of nitrite. Pink spots or colour only around the edges should not be interpreted as a positive result.
Protein: a green colour change indicates the presence of protein.
A positive result in one or more test areas does not automatically mean that you have a urinary tract infection. The manufacturer recommends consulting a healthcare professional about a positive result.
Does a negative result rule out a UTI?
No. A negative result from a UTI test kit at home cannot reliably rule out a urinary tract infection.
The nitrite test area may remain negative if the microorganism does not convert nitrate into nitrite, if the urine has remained in the bladder for less than 4 hours, during antibiotic treatment or when the diet contains little nitrate.
If symptoms of a urinary tract infection continue despite a negative result, contact a healthcare professional for further assessment.
How reliable is the UTI test kit?
The manufacturer’s instructions for use do not provide numerical clinical sensitivity or specificity values for this product. The test is designed to detect leukocytes, blood, nitrite and protein, but results may be affected by the interfering factors described in the instructions for use.
Visual interpretation can also be affected by lighting, colour vision and substances that alter the colour of urine. It is therefore important to follow the specified reading time and colour chart carefully.
What does the pack contain and how should the test be stored?
The pack contains:
- 1 test strip
- plastic cup
- colour chart
- instructions for use
You will also need a timer or a clock with a second hand.
Store the test dry in the sealed pouch at 2–30 °C. It may be stored at room temperature or refrigerated. Do not freeze. Do not use the test after the expiry date or if the foil pouch is damaged.
Frequently asked questions about the UTI test kit at home
What does the UTI test kit at home detect?
The UTI test kit at home detects leukocytes, blood, nitrite and protein in urine. Each parameter is interpreted separately using the supplied colour chart.
What does a positive result mean?
A positive result means that at least one test area has reacted for the relevant parameter. It does not automatically mean that you have a urinary tract infection.
Can only one of the four parameters be positive?
Yes. Each of the four test areas is interpreted separately, so one or more parameters may be positive while the others remain negative.
Can I rely on a negative UTI test result?
A negative result does not reliably rule out a urinary tract infection. For example, some bacteria do not produce nitrite, and insufficient time in the bladder may also produce a negative nitrite result.
When should the urine sample be collected?
The manufacturer recommends collecting urine early in the morning because it is usually most concentrated at that time.
Can antibiotics, medicines or vitamin C affect the result?
Yes. Antibiotics, high levels of ascorbic acid or vitamin C and certain medicines can affect the reaction of some test areas.
How quickly is the result ready?
The result is read after 2 minutes. Colour changes that occur after 3 minutes should not be used when interpreting the result.
Order the UTI test kit at home with four parameters when you want to check leukocytes, blood, nitrite and protein from the same urine sample.
