STI Checks
-
This is a highly confidential, discrete service. No notes have to be shared.
If you have recently had sex without a condom, a condom has broken or slipped, or you are concerned that you may have been exposed to an STI, it is important to test at the right time.
The window period is the time between becoming infected and the infection being reliably detected by a test. Testing too soon after exposure can sometimes give a negative result even though an infection is present.
As a general guide:
When to test after possible exposure:
Chlamydia: 2 weeks
Gonorrhoea: 2 weeks
HIV: A laboratory 4th-generation test is highly reliable from around 45 days (6½ weeks)
Syphilis: Up to 12 weeks may be required for a reliable result
Hepatitis B: Up to 12 weeks may be required
Hepatitis C: The timing depends on the test used and the type of exposure; further testing may be recommended
Genital herpes (HSV)Testing is generally most useful when symptoms such as blisters or sores are present
If in doubt book a consultation to discuss your needs with one of our doctors.
-
Don't wait for the window period if you have symptoms.
Symptoms such as unusual discharge, pain when passing urine, genital sores or ulcers, pelvic or testicular pain, or a new rash should be assessed by a healthcare professional. Testing may be appropriate sooner, and you may need a clinical examination or additional samples.
If you have had a recent high-risk exposure to HIV, seek urgent specialist sexual-health advice rather than waiting for a routine test, as post-exposure treatment (PEP) may be appropriate and needs to be started promptly.
