How to choose an at-home UTI test in the UK

Share this article

A home UTI test can show whether a urine sample has markers that are often linked to infection. It cannot confirm or rule out a UTI on its own. This guide explains what to look for in a kit, how the main routes compare, and when to get care instead.

What do UTI test strips check?

The U-Test UTI Test Kit is a urine dipstick screen. It checks the two markers on its chart: nitrites and leukocytes. Nitrites can appear when certain bacteria are present. Leukocytes are white blood cells, which can be raised when the body is responding to inflammation or infection. The result takes about two minutes to read. The U-Test UTI guide explains what each marker does and does not mean.

What to look for in a UTI test kit

  • Which markers it screens. The product page should name them.
  • Clear reading instructions. Time the reading as the leaflet says and compare against the chart.
  • Honest limits. A strip cannot say which bacteria are involved, or whether an antibiotic is needed.
  • Plain claims. Be wary of "diagnoses" or "confirms" wording.
  • Safety guidance. A good guide says when to get help whatever the strip shows.

How much does a UTI test cost?

The current price of the U-Test UTI Test Kit is shown on the product page, so it is always up to date. Remember that you do not have to buy a kit to be assessed. In England, a pharmacist can assess women and girls aged 16 to 64 who are not pregnant or breastfeeding and who may have a UTI, and can provide the same medicines as a GP where appropriate. Your GP or NHS 111 can also advise. Check what your local service offers.

Strip, pharmacist or GP?

Route Useful for Limit
Home dipstick A quick look at nitrites and leukocytes Cannot confirm or rule out a UTI
Pharmacist Assessment of symptoms and advice on next steps Not suitable for everyone; they may refer you
GP or NHS 111 Assessment, and further tests such as a urine culture if needed Appointment or call needed

When not to rely on a home test

Get urgent advice from a GP or NHS 111, rather than relying on a strip, if you have a high temperature, shivering, pain in your back or side, or blood in your urine. Men, anyone aged 65 or over, children aged 15 or under, anyone who is pregnant, anyone with a catheter, and anyone whose symptoms have not improved within 48 hours should also get clinical advice. Call 999 or go to A&E if you or your child are confused, very drowsy or have trouble speaking.

Common questions

Does a negative strip mean I do not have a UTI?

No. A strip can miss an infection. If you still have symptoms, speak to a pharmacist, your GP or NHS 111.

Can I use a home UTI test in pregnancy?

If you are pregnant and have urinary symptoms, get urgent advice from your GP, midwife or NHS 111 rather than relying on a home result.

Can a UTI go away on its own?

Sometimes symptoms settle without antibiotics, and a GP may suggest waiting a short time. Do not rely on that. Get advice if symptoms last, get worse or do not improve within 48 hours.
