What’s included
Included tests listed below
Swab culture (bacteria and yeast)
The swab is grown in the laboratory on media chosen for the site it was taken from, and any significant bacteria or yeast that grow are identified and reported. It is a general culture rather than a targeted test for sexually transmitted infections.
Overview
A bacterial culture of a cervical swab, taken by a clinician at the appointment. The laboratory grows what is present and reports any significant organisms and, where reported, antibiotic sensitivities. It is used when a clinician assessing cervical or pelvic symptoms wants a culture alongside, or instead of, PCR testing.
For someone under clinician assessment for cervical or pelvic symptoms where a culture is needed alongside or instead of PCR testing. It is a general culture, not an STI panel.
Who this is for and who it isn’t
Who it’s for
- Women aged 18 and over
- Women under clinician assessment for cervical or pelvic symptoms
- Anyone whose clinician has asked for a culture
Who it isn’t for
- It is not an STI screen, and chlamydia and gonorrhoea need PCR rather than culture. A cervical swab has to be taken by a clinician, so it is clinic only. If you are pregnant, or have had a gynaecological procedure recently, contact your midwife, GP or the team who treated you instead.
- Anyone with a new, severe or worsening symptom: contact your GP or call NHS 111. A test you buy today is not a substitute for being examined.
Common reasons people choose this test
- Cervical or pelvic symptoms under clinician assessment
- Discharge with a negative PCR panel
- Symptoms that came back after a course of treatment
- A clinician who has asked for a culture
These are reasons people choose to test, not signs that something is wrong. A result is one part of a picture your doctor puts together with your history and an examination.
What your result looks like
Every result is shown with the unit and the reference range exactly as the laboratory reported it, with the doctor’s note underneath.

How to prepare
What we can and can’t tell you
The reference range beside each result is the laboratory’s own. A result in range is not a clean bill of health and a result outside it is not a diagnosis. Most ranges cover about 95% of healthy people, so about 1 in 20 healthy people fall just outside any one range. No test result replaces an examination or your own doctor’s judgement, and none of these panels is a cancer screening programme.
Read the full note
A swab culture is not reported against a normal range. Many bacteria and yeasts live on healthy skin and in the genital tract, so what grows is read alongside your symptoms rather than on its own. It is a general culture, not a targeted test for sexually transmitted infections such as chlamydia, Mycoplasma genitalium, trichomonas, herpes or HIV, which need their own tests, and a result with no significant growth does not explain away symptoms that continue.
If you have symptoms that are new, severe or getting worse, contact your GP, an NHS sexual health clinic or NHS 111 rather than waiting for a result.
Frequently asked questions
How is a cervical swab taken?
During a speculum examination, in the same way as a smear. It takes a minute or two.
Why culture rather than PCR?
Culture picks up organisms a PCR panel is not designed to find and, where reported, shows which antibiotics work, which matters for stubborn or recurrent infection.
How long do results take?
The laboratory typically takes 3 to 5 working days from receiving your sample. This does not include kit delivery, sample collection or return postage. A doctor reviews your results before they are released.
Can I choose a home kit or a clinic?
This test uses a swab, not a blood sample, and it is taken at a clinic. We arrange a convenient appointment for you.
Is a doctor involved?
Yes. Every result is reviewed by a GMC-registered doctor who signs it off and explains what it means and what to do next.
Is it confidential?
Your results are available through your secure patient portal. Our privacy policy explains how your information is handled and when it may be shared to provide your care.
What happens to my sample and results?
Your swab is cultured at a UKAS-accredited laboratory (ISO 15189): it is grown on media chosen for the site it came from, and any significant organisms that grow are identified. A GMC-registered doctor then reads every result and signs the report before it is released to your secure portal, so nothing reaches you unreviewed. The report lists what grew, or that no significant growth was found, with the doctor's note on what it means alongside your symptoms and what usually happens next, which is most often a conversation with your GP or a sexual health clinic. If a result needs urgent attention, the reviewing doctor is alerted straight away and we contact you by phone the same working day rather than leaving it in the portal for you to find.
