STI window periods - helping you know when is best to get tested

The window period is the time between when a person comes in contact with a sexually transmitted infection (STI) and when the STI will show up on a test.

It is important to consider the window period when getting tested. Tests done too early may not be accurate. The time will vary from a few days to six months depending on the infection and the test. You can pass on an STI during the window period.

Find out the window periods for different STIs to help you know when you need to get tested.
