What is STD/STI Screening?
It’s a test or set of tests to check for infections that may not show symptoms, such as chlamydia, gonorrhoea, syphilis, HIV and others.
For individuals looking for STD screening in Singapore, early detection of STD leads to definitive treatment, reduction in complications of STD, and prevention of spread to other persons.
When symptoms are present, testing can usually be done promptly, and if needed, doctors can advise on suitable STD treatment in Singapore based on the condition diagnosed.
However, it is important to remember that an STD/STI may not have symptoms. When there are no symptoms, we generally recommend testing from 4-6 weeks after sex.
After someone becomes infected with an STD, there is generally a period of time before a test will be able to detect the infection. The period when the test is able to detect infection is called the window period. STD test windows vary.
The window period is different from the incubation period, which is the time it takes before symptoms first appear.
Regular and appropriate STD screening is the only way to confirm that a person is free from infection.
Cross Street Medical offers all relevant STD screening tests. Speak to our doctors about what you may need.
Why is screening important even without symptoms?
Many sexually transmitted infections do not cause noticeable symptoms in their early stages. Regular screening helps detect infections early, allowing timely treatment and preventing long-term complications or transmission to others.
