Overview of the Swab (Vulval) Test
The Vulval Swab test collects material from the external vulval area for microbiological culture, helping identify organisms that may contribute to local infection or inflammation.
The test assesses 1 specialist microbiology marker: Swab (Vulval).
The vulva includes the external female genital structures surrounding the vaginal opening.
Vulval itching, soreness, redness or discharge can arise from several different causes.
These include Candida infection, bacterial infection, dermatological conditions, allergic or irritant reactions and selected sexually transmitted infections.
A vulval culture focuses specifically on microorganisms present at the external genital site.
It is different from a High Vaginal Swab, which samples higher within the vagina, and different from molecular STI PCR tests designed to detect specific sexually transmitted pathogens.
A sterile culture swab is collected from the clinically affected area.
The laboratory then incubates the specimen and identifies clinically significant bacterial or fungal organisms where present.
Culture can be particularly useful when symptoms are recurrent, unusual or have failed to respond as expected to empirical treatment.
Interpretation needs care because normal genital and skin microorganisms can be present without causing infection.
The laboratory finding therefore needs to be considered alongside symptoms and the exact site from which the specimen was collected.
Where symptoms suggest a sexually transmitted infection rather than routine vulval infection, targeted PCR testing may be required instead.
What Does the Swab (Vulval) Test Check?
The test cultures material from the vulval area to identify bacterial or fungal organisms that may be associated with local infection. This test measures 1 specialist microbiology marker.
Swab (Vulval)
Cultures a professionally collected specimen from the external vulval area to identify clinically significant bacterial or fungal organisms where local infection is suspected.
Who May Benefit From the Swab (Vulval) Test?
A Vulval Swab can be useful where external genital symptoms suggest infection and direct microbiological assessment is required.
People with persistent vulval itching or irritation - Infection is one of several possible causes of external genital symptoms.
People with redness, soreness or inflammation of the vulval skin - Culture can help determine whether bacteria or fungi are present.
People with recurrent suspected Candida affecting the vulval area - Direct microbiological testing can be useful where symptoms repeatedly return.
People with local discharge or exudate from the vulval skin - A clinically affected area can be sampled directly.
People whose symptoms have not responded to initial treatment - Culture can help clarify whether infection is actually present.
People with recurrent vulval infections - Laboratory identification may help distinguish repeated infection from non-infectious vulval disease.
People with diabetes or immune suppression and recurrent symptoms - These conditions can increase susceptibility to selected infections.
People advised to undergo site-specific vulval culture - Professional collection can provide a specimen from the exact symptomatic area.
How to Prepare
There is no home or hotel collection option for this swab test.
The sample is collected in clinic from the appropriate symptomatic vulval area to support accurate site-specific microbiology.
Symptoms and Reasons to Consider the Swab (Vulval) Test
Vulval symptoms can arise from both infectious and non-infectious conditions, so culture is most useful where infection is clinically suspected.
Persistent vulval itching - Candida and other infections can cause itching, although dermatitis and irritation are also common.
External genital redness or soreness - Inflammation can occur with infection or non-infectious skin conditions.
Crusting, discharge or exudate from vulval skin - Visible material may allow targeted specimen collection.
Recurrent symptoms after treatment - Direct culture can help establish whether an organism remains present.
Fissuring or irritated skin with suspected secondary infection - Damaged skin can become secondarily infected.
Local pain or tenderness - Infection can contribute to discomfort.
Previous recurrent Candida or bacterial culture results - Repeat testing may help assess a new symptomatic episode.
Persistent symptoms with uncertain cause - A negative culture can also support consideration of dermatological or other explanations.
A Vulval Swab does not test comprehensively for every sexually transmitted infection.
Ulcers, blisters, significant pelvic symptoms or exposure to an STI may require dedicated PCR or sexual-health testing.
Persistent vulval symptoms despite negative infection testing can require gynaecological or dermatological assessment.

When Will I Receive My Results?
The specialist microbiology turnaround for a Vulval Swab culture is approximately 2–4 days after laboratory receipt.
The swab must be incubated to determine whether clinically significant organisms grow.
Further identification or sensitivity testing can occasionally extend reporting.
Turnaround begins once the correctly collected clinic specimen reaches the laboratory.
Understanding Your Results
A negative or no-significant-growth result means no clinically significant bacterial or fungal organism was recovered under the laboratory culture conditions.
This can make infection less likely, but non-infectious vulval conditions can still cause significant symptoms.
A positive result means an organism has been cultured.
The result needs to be interpreted according to the organism, amount of growth and clinical symptoms.
Normal skin or genital flora can sometimes appear in culture without being the cause of symptoms.
Candida or a clinically significant bacterial pathogen may be more relevant when symptoms and examination findings are compatible.
If STI exposure is a concern, a negative routine Vulval Swab does not replace targeted PCR testing for Chlamydia, Gonorrhoea, Trichomonas or other sexually transmitted pathogens.
