BV Testing
BV is now considered sexually transmissible following recent Australian research, but it is not a classic STI — it involves a shift in your own vaginal bacteria, not an organism caught from someone else. Testing is mainly for symptoms such as discharge or a fishy odour; BV with no symptoms usually does not need testing or treatment.
BV, thrush, and trichomoniasis can all cause discharge but need different treatments. The symptom alone cannot tell them apart, so a test confirms which one it is — treating the wrong cause will not fix the symptoms.
What BV actually is. Bacterial vaginosis is an imbalance in vaginal bacteria: the normal “good” lactobacilli decrease and a mix of anaerobic bacteria takes over, which raises the vaginal pH above its normal level. The classic sign is a thin grey or white discharge with a fishy odour, often more noticeable after sex or during a period. It is one of the most common causes of vaginal discharge, affecting around 30% of women.
Why the thinking changed. BV was long regarded as a simple bacterial imbalance with no sexual link. A 2025 Melbourne trial (the StepUp study) changed that: it found reinfection from a regular partner is a major driver of recurrence. It can still occur in women who have never been sexually active, and its discharge can look similar to trichomoniasis or thrush.
How the test works. The lab uses modern molecular (NAAT) testing on a self-collected vaginal swab, measuring the balance of vaginal bacteria directly — more reliable than the older clinical criteria. Pathology is covered by Medicare and most Private Health Insurers.
When to test. Test when you have symptoms — unusual discharge, odour, or irritation — or when symptoms have not settled after treating something else. It is worth testing while symptoms are present.
What a positive result means. A Specialist GP calls you to arrange treatment, and if BV and another cause are both found, both are usually treated. There is an alcohol-interaction caution with some treatments, which the Specialist GP will explain. Symptoms usually settle within a few days.
Recurrent BV. BV commonly comes back — over half of women have a recurrence within a year. Recent evidence has changed how this is managed: treating a regular partner with a penis at the same time as the person with BV significantly reduces recurrence. If yours keeps returning, a Specialist GP can talk through partner treatment and longer-term options rather than simply repeating the same short course each time.
What disturbs the balance. BV is not caught like a classic STI, but it is linked to sexual activity — new or multiple partners and unprotected sex can shift the vaginal microbiome. Douching, scented washes, and some lubricants can make it worse. Avoiding these, and treating a regular partner where advised, helps reduce how often it returns.
Frequently asked questions
Strictly speaking, no. BV is an imbalance in the normal vaginal bacteria, where the usual lactobacilli decrease and anaerobic bacteria take over. It is more common in sexually active women and certain sexual practices increase the risk, but it can also occur in women who have never been sexually active. BV is sometimes confused with an STI because the symptoms overlap with trichomoniasis (discharge, fishy odour) — but the bacteria that cause BV are different from STI bacteria.
The newer molecular tests have higher sensitivity than the older wet-mount microscopy approach — they detect cases that would have been missed clinically. They also do not require the lab to look at the sample under the microscope, which makes the test more practical at standard pathology providers. The trade-off is cost: the molecular test fee may be higher than basic microscopy. The Specialist GP discusses which approach makes sense at the consult.
Yes — that pattern is one of the classic presentations of BV. The fishy odour from BV becomes more noticeable after sex because semen is alkaline, which brings out the volatile amines produced by the BV bacteria. A vaginal swab for BV (with trichomoniasis testing on the same sample) is the standard approach. The Specialist GP can arrange this on a phone consult.
Sometimes, but a test is usually preferred because: BV symptoms overlap with other causes of vaginitis (trichomoniasis, candida, atrophic vaginitis), the bacteria pattern can change between episodes, and confirming BV before treatment is more reliable than self-diagnosis. For women with frequent recurrent BV who have a well-established pattern, the Specialist GP may sometimes arrange treatment based on symptoms alone — this is discussed at the consult.
Self-collected vaginal swab is the standard sample for the molecular BV test, so the collection part can be done at home. The swab is then taken to a pathology collection centre for processing. Some pathology providers accept the sample by post for routine testing, though same-day drop-off is more reliable. The Specialist GP sends the referral by SMS after the consult and discusses the practical options.
Typically 2 to 4 business days for the molecular test, depending on the pathology provider. Some providers process samples on specific days of the week which can add a day or two. If the result is urgent (severe symptoms in pregnancy, for example), the Specialist GP can sometimes have the result expedited.
A clinical diagnosis (based on history and examination findings) is reasonable for an initial BV presentation in a woman with classic symptoms (thin discharge, fishy odour, no STI risk factors). The Amsel criteria are still used in some sexual health clinics. A test becomes more important when symptoms recur, when BV has failed to clear after treatment, when there are other risk factors that make trichomoniasis or another cause possible, or when the symptoms are atypical.
Not routinely as part of antenatal screening in most parts of Australia. If you have vaginitis symptoms during pregnancy, testing is appropriate because untreated BV in pregnancy is associated with preterm birth and other complications. Treatment in pregnancy is safe and uses pregnancy-compatible regimens. The Specialist GP coordinates with your maternity team if any treatment is given.
Not automatically — the molecular BV panel tests for the BV-associated bacteria but does not cover chlamydia or gonorrhoea. However, a single vaginal swab can usually cover BV, trichomoniasis, chlamydia, and gonorrhoea testing if all are sent at once. The Specialist GP discusses what to include based on your symptoms and sexual history.
The pathology lab fee for BV testing has a Medicare item number that applies in specific situations (symptomatic presentations, recurrent BV, pregnancy with symptoms). The newer molecular panels may have a separate fee depending on the pathology provider. See our fees page for Clinic365 consult fees, and the Specialist GP can confirm the pathology fee structure at booking.
