Details about Urine Microscopy & Culture
What is the Urine Microscopy & Culture test?
Urine Microscopy & Culture is a laboratory test that examines a urine sample in two stages. Microscopy looks at urine under a microscope to identify white blood cells, red blood cells, bacteria, crystals, and casts. Culture involves growing any bacteria present to confirm infection.
This combined approach provides both immediate indicators of infection or inflammation and definitive identification of bacterial growth. It is one of the most reliable tests for diagnosing urinary tract infections (UTIs).
The test can also provide insight into non-infective urinary abnormalities.
Why do I need a Urine Microscopy & Culture test?
Urinary symptoms can be caused by infection, inflammation, stones, or other urinary tract issues. This test helps determine the underlying cause accurately.
You may need this test if you experience:
- Burning or pain when passing urine
- Frequent or urgent urination
- Cloudy or strong-smelling urine
- Lower abdominal or pelvic pain
- Blood in the urine
- Fever with urinary symptoms
- Recurrent urinary symptoms
- Monitoring response to previous treatment
The test helps distinguish true infection from non-infective causes of symptoms.

Follow these guidelines for accurate results
Sample Timing
Where possible, attend your blood test between 7am and 12pm. Please wait until any short-term illness or infection has fully resolved before testing. Avoid intense exercise for 24–48 hours beforehand, as this can affect certain markers.
Fasting & Hydration
Fasting is not always required, but some tests may recommend it. If fasting is advised, avoid food for 8–12 hours before your appointment and drink water only. Stay well hydrated, as this helps with sample collection and accuracy.
Medications & Supplements
Continue prescribed medications unless advised otherwise by your clinician. Avoid vitamin, mineral, or biotin supplements for at least 24–48 hours before your test, as these can interfere with results. If you are unsure about any medication or supplement, please let us know before your appointment.
Hormones & Menstrual Cycle
For hormone-related tests, timing within your menstrual cycle may be important. If relevant, follow any specific guidance provided on your test page.
If you have any questions or special circumstances, our team is happy to advise before your appointment.
