When should I test after last high-risk sexual behavior?

The time between one infection and when a test can reliably detect that infection is window period. Different STIs have different window periods, and it depends on test methods. These four STIs (HIV, HBsAg, TP and HSV-2) have window periods up to 12 weeks. Although encouraging, a Negative result may not be accurate until 12 weeks after possible infection in case the person has not yet made antibodies. You can perform this test 4 weeks later since your last high-risk sexual behavior, and should check every 4 weeks until 12 weeks.

How accurate is the staysafe® 4-in-1 STI Rapid Test?

What do I do if my result is Positive?

If your result indicates HIV Positive, do not panic. You MUST consult a healthcare professional who will confirm your result.

1. Please call AIDS Hotline (2780 2211) or Gay Men HIV Testing Hotline (2117 1069) for an urgent appointment
2. 2. You may contact one of government and/or non-governmental organizations (NGOs) that provide confirmatory test, such as AIDS Concern, Community Health Organisation for Intervention, Care and Empowerment, Hong Kong ADIS Foundation, Midnight Blue, Rainbow of Hong Kong.
3. You may consult with your family doctor to have a confirmatory test.


If your result indicates HBsAg/TP/HSV-2 Positive, you should consult a healthcare professional as soon as possible. Do not take medication without prescription, as it may cause serious health problems to you and your partner. You may seek help from a nearby Social Hygiene Clinic (Male) or Social Hygiene Clinic (Female).
