Sexual Health FAQ
Frequently asked clinical questions about our London STI clinic.
When Should You Get Tested for STIs?
Regular sexual health screening is an important part of looking after your wellbeing. Public Health England and BASHH recommend testing if you have had unprotected sexual contact, are starting a new relationship, have multiple partners, or are experiencing any symptoms such as unusual discharge, discomfort, or skin changes.
It is important to be aware of the 'window period' — the time between potential exposure and when an infection becomes detectable. For bacterial infections like Chlamydia and Gonorrhoea, testing is typically accurate from 14 days post-exposure. For HIV, our 4th generation antigen/antibody tests provide reliable results from 28 days, with conclusive results at 90 days post-exposure.
Many sexually transmitted infections are asymptomatic, meaning you may have an infection without experiencing any noticeable symptoms. This is why routine screening is the only way to be certain of your sexual health status.
