Doctor's Assessment Included
Every result includes a professional assessment from a BIG-registered doctor. For treatment decisions, discuss your results with your GP.
Urine Culture
A urine culture helps identify bacteria causing urinary tract infections in men. While UTIs are less common in men than women, they can be associated with prostate conditions and tend to be more complicated, making accurate culture-guided treatment important.
What It Measures
A urine culture involves incubating a urine sample under controlled conditions to promote the growth of any bacteria or organisms present. The type and quantity of organisms are then identified.
Antibiotic sensitivity testing (antibiogram) is typically performed alongside the culture to determine which antibiotics the identified organisms are susceptible to, enabling your healthcare provider to prescribe the most effective treatment.

Why It Matters
Urine cultures are essential for accurately diagnosing urinary tract infections and ensuring appropriate treatment. While simple UTIs may respond to empirical antibiotic therapy, complicated or recurrent infections require culture-guided treatment to prevent antibiotic resistance.
Untreated or improperly treated UTIs can progress to more serious conditions such as pyelonephritis (kidney infection) or sepsis. Identifying the specific causative organism helps prevent these complications.

When to Test
A urine culture may be recommended when UTI symptoms are present, such as burning during urination, frequent urge to urinate, or cloudy urine. It is particularly important for recurrent UTIs, complicated infections, or when initial antibiotic treatment has not been effective.
It may also be ordered during pregnancy as part of routine screening, or for individuals with urinary catheters or structural abnormalities of the urinary tract.

Symptoms
Low Levels
A negative urine culture indicates no significant bacterial growth, which generally suggests a healthy urinary tract without active infection.
High Levels
Burning or pain during urination
Frequent and urgent need to urinate
Cloudy, dark, or strong-smelling urine
Pelvic pain or pressure
Fever and chills if infection has spread

Recommendations
Male
If Low
Negative urine culture indicates no bacterial infection. No treatment needed.
If High
Positive urine culture indicates a urinary tract infection. Consult your healthcare provider for appropriate antibiotic treatment.
Lifestyle Tips
Stay well hydrated to help flush bacteria from the urinary tract. Practice good hygiene, including wiping front to back and urinating after intercourse. Avoid holding urine for extended periods.
Wear breathable, cotton underwear and avoid irritating feminine hygiene products. Cranberry products may offer modest benefit for some individuals, though evidence is mixed. Complete any prescribed antibiotic courses fully, even if symptoms improve.

Frequently Asked Questions
How long does a urine culture take?
A urine culture typically takes 24 to 72 hours to produce results, as the sample must be incubated to allow bacteria to grow. Antibiotic sensitivity results may take an additional day. Your healthcare provider will inform you when results are available.
What does a positive urine culture mean?
A positive urine culture means that bacteria or other organisms were detected in your urine sample above a threshold that may indicate infection. The results will identify the specific organism and which antibiotics it is sensitive to, guiding your treatment.
Can a urine culture detect all types of infections?
Standard urine cultures are designed to detect common bacterial infections. Some organisms, such as certain fungi or sexually transmitted infections, may require specialised testing. Your healthcare provider will determine the appropriate tests based on your symptoms.
