UK healthcare guide · Updated 30 September 2026
A painful blister, a new partner or an unexpected symptom can leave you unsure what to ask for at a sexual health clinic. If you are looking for an NHS sexual health clinic herpes test, start by telling the service whether you have a visible sore. That detail helps staff arrange the right appointment and decide whether a herpes swab is possible.
This guide follows the practical steps of a clinic visit using published NHS and clinic information. Appointment booking procedures and laboratory times vary locally, so the examples below are useful planning information rather than a promise about your own visit.
Before you go: can you walk in?
Sexual health clinics may also be called GUM clinics. The NHS says some accept people without an appointment, but recommends checking first. A clinic’s opening hours do not necessarily mean that every service is available throughout the day. NHS: visiting a sexual health clinic.
For a concrete London example, 56 Dean Street’s testing page directs people with genital ulcers or painful blisters to call for an appropriate appointment. People wanting a routine check without symptoms can use a home sampling kit or collect one from reception. Walking in to collect a kit is a different service from being examined for a new sore.
There is no single national walk-in waiting time. If you are reading a GUM clinic walk-in review in the UK, check when it was written and whether the person attended for symptoms, a routine screen or an urgent concern. A useful call to reception is: “I have a new painful genital sore. Do I need an appointment, and which clinic should I attend?” Ask whether you should leave extra time beyond the appointment itself.
Checking in and discussing your symptoms
You will usually give contact details and speak with a clinician about your symptoms and sexual history. Note when the sore first appeared and any treatment you have already used. If the words are difficult to say aloud, bring a short written description.
You can ask for a chaperone, or request a female or male clinician; availability may affect the wait. Staff should explain the suggested examination and tests. You can ask what a sample is for before it is collected. NHS: finding STI testing and treatment.
How herpes testing differs from a routine STI screen
A routine urine or blood screen does not automatically include a herpes test. For suspected genital herpes, a clinician usually takes a swab from a visible blister or ulcer. Sexual Health Wirral explains this diagnostic route and advises attending while symptoms are present. Tell reception about the sore when booking rather than selecting a symptom-free screening appointment.
The swab may briefly sting if the area is tender. Other samples may be recommended according to your history, but they answer different questions. Ask: “Was this sample tested for herpes, and will the result identify HSV-1 or HSV-2?”
Herpes antibody blood tests need careful interpretation. The BASHH 2024 anogenital herpes guideline describes limitations, including delayed antibody development and false positive results. A blood test is not a simple substitute for examining and swabbing an active sore. If you have no symptoms, ask a sexual health clinician whether testing would be useful in your circumstances.
When will results arrive?
The NHS describes same-day results for some tests and a wait of one or two weeks for others. Ask which timeframe applies to your samples and how to contact the clinic if nothing arrives. Silence should not be treated as a negative result.
Herpes-specific timing may differ from a clinic’s headline screening turnaround. Croydon Sexual Health’s herpes information gives a usual wait of one to three weeks. That local estimate is a useful reminder to ask about the actual test you had.
Before leaving, write down the expected result date and the clinic’s contact route. Also ask what to do if the symptoms worsen while you wait. A diagnosis cannot tell you exactly when the infection was acquired or who passed it on. NHS: genital herpes.
Confidentiality and text messages
NHS sexual health visits are confidential; your GP is not normally informed without your permission. There are safeguarding exceptions if staff believe someone is at risk of harm. Results may be sent by text, phone or unmarked letter, depending on the service.
If someone else can see your phone, discuss a safer contact method at reception. Check that the clinic has the right number, and ask what the message will contain. You can also turn off lock-screen message previews on your own device.
NHS clinic or private STI test?
NHS STI information and testing are free. When comparing a private STD test with the NHS, ask about the sample type, the infections included and whether the price covers a clinician’s interpretation and follow-up. Paying for a larger panel does not automatically make it the appropriate herpes test.
Private services may offer appointment or delivery options that fit your schedule. Check the full cost and the timing from sample receipt, rather than assuming a quoted laboratory turnaround includes postage. For active painful sores, consider whether waiting for a postal kit would delay clinical assessment.
Moving Beyond the Clinic Visit
Walking out of a sexual health clinic with an unexpected diagnosis can feel isolating. Practical medical information helps, but questions about relationships may remain after the appointment.
For a personal perspective, read James’s account of dating with herpes in London. His story explores the emotional adjustment after diagnosis and finding confidence again. You can also explore PositiveSingles UK for peer connection. A dating community can offer social support; clinical questions belong with a qualified healthcare professional.
A simple checklist before you go
- Check the clinic’s current booking instructions and mention visible sores.
- Bring the dates of your symptoms and a list of medicines you take.
- Ask which tests will be done and whether a herpes swab is included.
- Choose a contact method that is private for you.
- Record when results are expected and who to contact if they do not arrive.
If this is your first suspected outbreak, contact a sexual health clinic promptly. If you are pregnant, tell your midwife or GP about possible genital herpes. The NHS genital herpes guidance explains why assessment and treatment matter.
