Frequently Asked Questions
Common questions about abnormal vaginal discharge and testing.
Q
Is abnormal vaginal discharge always a sign of an STI?
+
No. Abnormal discharge is often caused by non-STI conditions such as bacterial vaginosis, candidiasis (thrush), or normal hormonal changes during your cycle. STIs including chlamydia, gonorrhoea, and trichomoniasis can also cause it. Colour and smell alone can't tell you which — a laboratory test is the only reliable way to know the cause.
Q
Is it safe to buy medication for discharge without getting tested first?
+
Treating discharge without knowing the cause risks masking symptoms, delaying the right treatment, and — for STI causes — makes it harder to protect a partner from infection. The World Health Organization notes that inappropriate selection and overuse of antibiotics is one driver of rising antibiotic resistance in gonorrhoea. Testing first means treatment, if needed, targets the actual cause.
Q
Can a swab test tell me exactly what's causing my discharge?
+
A PCR test detects a pathogen's genetic material directly and can identify infections such as chlamydia, gonorrhoea, or trichomoniasis. Which specimen is collected affects what the test can find, so it matters that the sample matches your specific symptoms. Non-infectious causes, like bacterial vaginosis or candidiasis, are usually assessed by other means during the same visit.
Q
How soon after a possible exposure should I get tested?
+
Tests for infections like chlamydia, gonorrhoea, and trichomoniasis have an early window period after a possible exposure. Testing too soon can give a false negative result, and repeat testing may be needed depending on how much time has passed since the exposure. Speak to our clinical team about timing for your specific situation.
Q
Is testing for abnormal discharge confidential at CA Medlynks?
+
Yes. Testing takes place in a private consultation room with confidential protocols, and you'll discuss your symptoms directly with our clinical team rather than describing them at a front desk. This is the same standard of confidentiality used across all testing at CA Medlynks.
