Thrush check-up (Vulvovaginal candidiasis (thrush) assessment)

An assessment to confirm whether your symptoms are caused by thrush (a common yeast called candida) and to rule out other conditions that can look similar.

✓ Medically reviewed by a GMC-registered consultant · last reviewed September 2026 · next review September 2027 · how we review

In short

A thrush assessment confirms whether candida is the real cause of your symptoms — many similar-looking conditions are not thrush.
Thrush is common and is not classed as a sexually transmitted infection; you do not usually need to treat a partner who has no symptoms.
Most thrush settles within 1–2 weeks of antifungal treatment; recurrent thrush (four or more episodes a year) may need a longer treatment plan.
If you are unsure, pregnant, keep getting symptoms, or treatment has not worked, get assessed rather than self-diagnosing repeatedly.

What is a thrush (candida) assessment?

Thrush is a very common infection caused by a yeast called candida, which normally lives harmlessly on the skin and inside the body. Thrush happens when candida multiplies and causes itching, soreness and discharge. It is not classed as a sexually transmitted infection, although it can sometimes be passed on during sex.

A thrush assessment is the appointment where a clinician listens to your symptoms, may examine the area, and sometimes takes a swab. The aim is to confirm whether candida really is the cause, because several other conditions — including some skin conditions, bacterial vaginosis, and sexually transmitted infections — can feel or look very similar.

The assessment also looks for anything that might make thrush keep coming back, such as poorly controlled diabetes. It cannot, on its own, treat the cause of recurrent thrush, but it points you towards the right treatment and any further checks.

Many people treat occasional thrush themselves with pharmacy antifungal medicine. An assessment matters most when you are not sure of the diagnosis, when it keeps returning, when treatment has not worked, or when you are pregnant.

Types, options & approaches

There may be different ways to do this. The right approach depends on the clinical question and your circumstances.

Talking through your symptoms (history)

The clinician asks about itching, soreness, discharge, pain passing urine or during sex, how often it happens, what you have already tried, and anything that might make thrush more likely, such as antibiotics, pregnancy or diabetes.

Examination

Looking at the affected skin and, in women, sometimes an internal (speculum) examination. This helps tell thrush apart from skin conditions, eczema, or other infections.

Vaginal or skin swab

A swab can confirm candida and identify the type of yeast. It is not always needed for a first, typical episode, but is useful when the diagnosis is unclear, when symptoms keep returning, or when usual treatment has failed.

Tests for other causes

If the picture does not fit thrush, the clinician may test for sexually transmitted infections or bacterial vaginosis, or check for diabetes, so the real cause is not missed.

Recurrent thrush review

If you get thrush four or more times in a year, the assessment focuses on confirming the diagnosis with a swab and planning a longer course of treatment and good skin care.

Thrush versus other common causes of similar symptoms

Feature	Thrush	Other causes
Discharge	Thick, white, often like cottage cheese	Bacterial vaginosis: thin, grey, fishy smell
Main symptom	Itching and soreness	STIs may cause discharge, pain or no symptoms
Smell	Not usually smelly	A strong smell points away from thrush
Best check	Often clinical; swab if unclear	Swabs or STI tests confirm the difference

Symptoms overlap a lot, which is exactly why guessing can be wrong. A clinician or swab can tell these apart.

Preparing for your test

Note how many times you have had these symptoms in the last year, and what treatments you have tried.
Avoid using antifungal cream or pessaries for a day or two before a swab if you can, as recent treatment can affect the result — ask the clinic what they prefer.
Try not to be on your period for a planned swab, as this can make sampling harder.
Avoid scented soaps, douches and washes before the appointment, as these can irritate the skin and confuse the picture.
Bring a list of your medicines, including recent antibiotics, steroids or hormone treatments.
Mention if you are or might be pregnant or breastfeeding, as this changes which treatments are safe.
Tell the clinic if you have diabetes or a weakened immune system.

What happens

The clinician will ask about your symptoms and what you have already tried. With your consent, they may examine the affected skin, and in women may offer an internal examination using a speculum to look at the vagina and cervix.

If the diagnosis is not clear, or if symptoms keep coming back or have not responded to treatment, a swab may be taken from the affected area. This is quick and is sent to a laboratory to confirm candida and, if needed, identify the exact type of yeast.

If the picture suggests something other than thrush, the clinician may suggest tests for sexually transmitted infections or other causes. They will explain what they think is going on and the treatment options before you leave.

Is this test right for me?

A good consultation should explore whether it's the right choice for you now — including reasons to wait or consider something else.

May not be suitable if…

Self-treatment is not appropriate if you are under 16 or over 60, pregnant, or have never had thrush confirmed before.
A simple thrush assessment is the wrong pathway if you have severe pelvic pain, fever or feel very unwell — this needs urgent assessment for other causes.
It is not the right approach to keep treating recurrent symptoms as thrush without ever confirming the diagnosis with a swab.
It will not address an underlying problem such as poorly controlled diabetes, which needs separate management.

Delay or rearrange if…

You are using antifungal cream or pessaries, as recent treatment can affect a swab — discuss timing with the clinic.
You are on your period, for a planned swab.
You have new symptoms suggesting another infection that should be tested for at the same time.
You are pregnant — get advice on safe treatment before using anything.

Alternatives to discuss

Pharmacy self-care with antifungal medicine for a typical recurrence in someone previously diagnosed.
An NHS GP or sexual health clinic appointment rather than private.
Testing for bacterial vaginosis or STIs if the picture does not fit thrush.
Reviewing skin care and irritants, which is central to managing recurrent thrush.

Before you decide

Use this as a shared-decision checklist. The aim is not just “can this be done?”, but whether it is right for you, now, with the risks and alternatives clearly understood.

What matters most to me?

Think about symptoms, daily life, work, caring responsibilities, sport, fertility, travel, appearance and anxiety — the right choice depends on your priorities, not just the medical facts.

What are all my options?

Ask about waiting, monitoring, medicines, rehabilitation, a smaller or larger procedure, a different test, NHS referral, or a second opinion where that would help.

What would make me pause?

Active infection, pregnancy, unstable medical problems, smoking, medicines that increase bleeding, poor support at home, or feeling pressured are all reasons to slow down and get tailored advice.

What happens if I do nothing today?

For some problems, waiting is safe; for others, delay can make treatment harder. A good consultation should explain the trade-off in plain English.

Benefits

Confirms whether candida really is the cause, rather than guessing
Rules out conditions that look similar but need different treatment, including some STIs
Identifies things that make thrush keep coming back, such as poorly controlled diabetes
Guides the right treatment, including a longer plan for recurrent thrush
Offers reassurance and clear information when you are worried

Risks & complications

More common

Mild, brief discomfort during an internal examination or swab
Slight spotting after a swab
Feeling self-conscious or embarrassed (clinicians do this routinely and without judgement)

Less common

The swab does not give a clear answer and needs repeating
A normal swab despite real symptoms, because samples can miss yeast
Symptoms turning out to be something other than thrush, needing further tests

Rare but serious

Missing a different, more serious cause if assessment is rushed or self-diagnosis is relied on repeatedly

The main risk is not the assessment itself but getting the wrong diagnosis. Treating something as thrush when it is not — for example bacterial vaginosis, a skin condition, or an STI — can delay the right treatment. Ask your clinician what else it could be and whether a swab would help if you are not improving.

Published figures to discuss

Thrush is common and usually responds to treatment, but figures vary because thrush is often diagnosed on symptoms alone, swabs are not always taken, and candida can be found in people with no symptoms. We have not put precise percentages on diagnosis or recurrence because they depend heavily on the population and how the diagnosis was made.

Figure	Reported range	How to interpret it	Source / confidence
Symptoms not actually due to thrush	Common diagnostic pitfall	BV, herpes, dermatitis, vulval pain syndromes and STIs can mimic thrush, especially when symptoms recur.	Guide sourcesClinical context
Recurrent vulvovaginal candidiasis	Recognised pattern, usually defined as repeated episodes over a year	Recurrent symptoms should prompt confirmation, diabetes/immunosuppression review and a longer management plan.	Guide sourcesClinical context

These are literature figures, not a personalised prediction. Your own risks and likely benefits depend on your circumstances, your health, and how your care is carried out and followed up.

What happens afterwards

There is no physical recovery from a thrush assessment. "Afterwards" mainly means starting any treatment and knowing when to expect swab results or to return.

Straight after the appointment

You can return to normal activities immediately. If a swab was taken, you may have very light spotting for a short time.

First few days

If you start antifungal treatment, itching and soreness usually begin to ease. Swab results, if taken, are often back within a few days.

1–2 weeks

Most thrush clears within 7 to 14 days of starting treatment. If symptoms have not settled, contact the clinic — you may need a different treatment or further tests.

If recurrent

For thrush that keeps coming back, a longer treatment plan over several months may be started, with review to check it is working.

What's normal — and not a worry

Itching and soreness easing over several days of treatment
A short wait for swab results if one was taken
Mild irritation from antifungal creams in some people
No immediate change if you are waiting on results before starting treatment

Aftercare

Use any antifungal treatment exactly as directed, and finish the course even if you feel better.
Avoid scented soaps, shower gels, douches and feminine hygiene products, which irritate the skin.
Wear loose cotton underwear and avoid tight synthetic clothing where you can.
Avoid sex until you are comfortable, and remember some antifungal products can weaken condoms and diaphragms.
If you are pregnant or breastfeeding, only use treatments your clinician has approved.
Go back if symptoms do not settle within 1–2 weeks, or keep returning.
Keep any follow-up or review appointment for recurrent thrush.

Before your test

A note of how often symptoms have happened this year
A list of treatments already tried
Your current medicines, including recent antibiotics
Whether you are or might be pregnant
Questions about what else it could be
The clinic's contact route if you do not improve

⚠ Get urgent help if…

Fever, severe pelvic or lower tummy pain, or feeling very unwell — this is not typical of thrush and needs urgent review
Symptoms that do not improve after 1–2 weeks of treatment
Thrush returning four or more times in a year
Bleeding between periods or after sex, or an unusual or smelly discharge
A sore, ulcer, lump or rash on the genitals that does not settle
Being pregnant with thrush symptoms — get advice before treating
Thrush with poorly controlled diabetes or a weakened immune system

Who to contact: your clinician, clinic or test provider first (keep their number to hand). For urgent advice when you can't reach them, call NHS 111. In an emergency, call 999.

General guidance — it doesn't replace the specific advice your specialist gives you.

Results & realistic expectations

A clear result means your clinician is confident the cause is candida and can recommend treatment, or has identified another cause that needs different treatment. A swab can confirm candida and the type of yeast, which matters when usual treatment has not worked.

A normal swab does not always rule thrush out, because samples can miss yeast, and a positive swab in someone with no symptoms does not always need treating. Results are interpreted alongside your symptoms, not on their own.

How long it lasts

An assessment reflects your situation at that time. Thrush can come back, especially around periods, pregnancy, after antibiotics, or with diabetes. If symptoms return, the diagnosis may need confirming again rather than assuming it is the same thing.

Related tests, treatments or support

A thrush assessment is often done alongside a wider sexual health check, especially if there is any chance of a sexually transmitted infection or if symptoms do not fit thrush neatly. Testing for other causes at the same time avoids repeated visits.

Follow-up & long-term care

Most people do not need routine follow-up after a single, typical episode that responds to treatment. You should return if symptoms persist, recur, or change. For recurrent thrush, follow-up is planned to check the longer treatment course is working and to review skin care.

Good vulval skin care — avoiding soaps and irritants — is the mainstay of preventing recurrent thrush.
Managing diabetes well, if you have it, reduces how often thrush returns.
A planned longer antifungal course may be used for recurrent thrush, with review.

Repeat, follow-on and what comes next

A swab may need repeating if it is unclear or treatment has not worked.
If symptoms persist or recur, the diagnosis may need revisiting rather than assuming it is the same thing.
Recurrent thrush often needs a longer treatment course and a review, not just repeated short treatments.

Ask what happens if the result is unclear or needs repeating, and what is included if further tests or follow-up are needed.

What good aftercare looks like

Clear advice on how to use treatment and how long it should take to work.
A named route to come back if symptoms do not settle or keep returning.
A plan to confirm recurrent thrush with a swab and arrange a longer treatment course.
Sensible vulval skin-care advice and a check for triggers such as diabetes.

What affects the cost

Costs vary a great deal between people and providers, and we don't publish prices. What matters is understanding what drives the cost and making sure your quote is complete. The main things that affect it:

Whether the appointment is a short consultation or a longer assessment for recurrent symptoms
Whether a swab or other laboratory test is taken
Tests for other causes, such as STIs or blood sugar, if needed
Whether antifungal treatment is included or bought separately
Any follow-up appointment for recurrent thrush
The clinician's professional fee and the clinic facility fee

Make sure your written quote includes

The clinician's consultation fee
Whether any swab or laboratory test is included, and its cost
Whether additional tests for other causes are included
Whether medicines are included or prescribed separately
Any charge for a follow-up or review appointment
What happens, and what it costs, if results are inconclusive or symptoms recur

On the NHS? Thrush assessment and treatment are widely available on the NHS through GPs, pharmacies and sexual health clinics; private appointments may be used for speed, privacy or choice.

You're entitled to your total cost in writing — including reports, follow-up and what happens if the result is inconclusive — before you decide.

Frequently asked questions

Is thrush a sexually transmitted infection?

No. Thrush is caused by candida, a yeast that normally lives on the body. It is not classed as an STI, although it can occasionally be passed on during sex. You do not usually need to treat a partner who has no symptoms.

Do I need to see a doctor, or can I treat it myself?

If you have had thrush diagnosed before and recognise the symptoms, a pharmacist can recommend treatment. See a clinician if you are unsure, pregnant, under 16 or over 60, keep getting it, or treatment has not worked.

Why does my thrush keep coming back?

Recurrent thrush means four or more episodes in a year. Triggers include antibiotics, hormonal changes, pregnancy and poorly controlled diabetes. An assessment, usually with a swab, helps confirm it and plan a longer treatment course.

Could my symptoms be something other than thrush?

Yes. Bacterial vaginosis, skin conditions, eczema and some STIs can feel similar. That is why a clinician or a swab can be helpful, especially if treatment has not worked.

Can I have a swab during my period?

It is usually best to avoid sampling during your period, as it can make the swab harder to interpret. Ask the clinic about timing when you book.

Is thrush dangerous?

Thrush itself is usually harmless and treatable. The main risk is mistaking something else for thrush. Fever, severe pelvic pain, or a sore or lump that does not settle are not typical of thrush and need review.
