Urinary symptoms are difficult to ignore. A burning sensation when you urinate, repeated trips to the bathroom or a constant feeling that you need to go can quickly become uncomfortable.
A urinary tract infection is one possible cause.
UTIs are common, particularly infections involving the bladder, but symptoms alone are not always enough to confirm what is happening. A urine test can provide useful additional information.
What does a UTI usually feel like?
One of the most common signs is pain or burning while urinating. You may also feel the need to go more often, even when very little urine is passed.
Other symptoms can include:
- Cloudy urine
- Lower abdominal discomfort
- Urine that smells stronger than usual
- Blood in the urine
- A sudden increase in urinary urgency
Not everyone experiences the same combination of symptoms.
Strong-smelling or darker urine can sometimes be caused by dehydration, for example. Irritation and other infections may also cause symptoms that resemble a UTI.
What does a UTI test measure?
A rapid UTI Test checks urine for markers that may be associated with infection or inflammation.
Depending on the test, these can include leukocytes, nitrite, blood and protein.
Leukocytes are white blood cells that may appear when the immune system is responding to an infection. Certain bacteria can convert nitrates in urine into nitrites, so the presence of nitrite can also support the suspicion of a bacterial UTI.
Blood or protein in the urine may provide additional information, although these markers are not specific to urinary tract infections.
A test strip cannot therefore identify every possible infection or explain every urinary symptom.
Can you have a UTI with a negative test?
Not every bacterium linked to a UTI produces nitrite. The concentration of the urine and the timing of the test can also affect the result.
A negative result should not automatically be taken as proof that there is no infection.
If the symptoms are mild and disappear quickly, further investigation may not always be necessary. If they continue, become more painful or keep returning, it is worth seeking medical advice.
A healthcare professional may decide to send a urine sample to a laboratory. A urine culture can provide more detailed information about whether bacteria are present and, in some cases, which treatment is likely to be effective.
When symptoms need medical attention
A bladder infection is usually the first thing people think of when they hear the term UTI. In some cases, however, an infection can travel further up the urinary tract and affect the kidneys.
Fever, chills, nausea or pain in the back or side should therefore be taken seriously.
Medical advice is also sensible if there is visible blood in the urine, symptoms are severe or infections keep returning.
Pregnant women, children, men with UTI symptoms and people with certain medical conditions may also need professional assessment rather than relying only on a home test.
Why home UTI tests can be useful
For mild symptoms, testing at home can be a convenient first step.
Companies such as GetTested offer rapid tests designed to detect several common urinary markers. Being able to test without visiting a clinic can be useful when symptoms have only just started or when you want more information before deciding what to do next.
A result is most useful when considered alongside the symptoms.
A positive result may support the suspicion of a UTI. A negative result may still require follow-up if the discomfort does not go away.
Do not rely on the test alone
Rapid urine tests can be helpful, but they are not a replacement for medical assessment when symptoms become more serious.
Pay attention to how you feel as well as what appears on the test strip.
If the burning, urgency or discomfort continues, or if you develop a fever or pain around the kidneys, further investigation is more useful than repeatedly testing at home.
Used sensibly, a UTI test can help you decide whether the symptoms are consistent with a urinary infection and whether it is time to seek further advice.
