What is the Swab for Culture Test?

A swab for culture involves collecting a sample from an affected body site using a sterile swab. The sample is grown in the laboratory to identify bacteria or fungi that may be causing infection.

This test can be performed on many sites, including wounds, skin lesions, throat, nose, genital areas, ears, or areas with discharge. Culture testing allows laboratories to identify organisms and assess their growth characteristics.

Swab culture is especially useful when infections are recurrent, not responding to treatment, or when precise identification of the organism is required.

Why do I need a Swab for Culture test?

Some infections cannot be reliably identified based on symptoms alone. Swab culture testing helps confirm the presence of infection and distinguish between harmless colonisation and clinically significant pathogens.

You may need this test if you experience:

• Persistent or recurrent infections
• Wounds that are slow to heal
• Redness, swelling, or discharge from a site
• Pain or tenderness around a lesion
• Recurrent skin or soft tissue infections
• Symptoms not improving with initial treatment
• Suspected bacterial or fungal infection

Accurate identification supports appropriate clinical decision-making and follow-up.

Benefits of the test

1. Identifies the exact organism
   Allows precise identification of bacteria or fungi.
2. Applicable to multiple body sites
   Flexible testing from skin, wounds, throat, or other areas.
3. Useful for persistent infections
   Helps when symptoms recur or do not resolve.
4. Supports targeted clinical decisions
   Results help guide appropriate follow-up.
5. Distinguishes infection from colonisation
   Helps interpret whether organisms are clinically relevant.
6. Widely used diagnostic method
   A standard and well-established laboratory technique.
7. Useful in wound and skin care
   Commonly used for infected or non-healing wounds.
8. Reduces uncertainty
   Provides clear laboratory confirmation of infection.

Step-by-step: How we offer testing

Clinic-based testing (UK-wide)

• Sample is sent to the laboratory
• Results are issued once analysis is complete

Home or hotel visit (+£60, UK-wide)

• Book a mobile clinician
• Swab taken at your home or hotel
• No clinic visit required
• Sample securely transported to the laboratory

Your results explained

No growth (normal)

• No clinically significant organisms grown
• UK standard: No growth
• Suggests no active bacterial or fungal infection

Low growth / mixed flora

• Small amounts of organisms or mixed bacteria present
• UK standard: Scant growth / mixed skin flora
• May represent colonisation rather than infection

Positive culture (significant growth)

• One or more organisms identified
• UK standard: Organism reported by name
• Indicates active infection requiring clinical interpretation
