The short explanation
A negative HIV test at two weeks is reassuring but not final. HIV tests have a window period, the time between infection and when a test can detect it. Depending on the type of test, this can range from about two weeks to three months. So a repeat test is usually advised at around six weeks and again at three months after the exposure to be sure. Anxiety while waiting is very common. Talking to a counsellor at an ICTC or STI clinic can help; they are trained to support people in this situation. If you were not given PEP and the exposure was more than 72 hours ago, PEP is no longer useful, but testing and support are.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Use condoms with partners until you have your final result.
- Testing for other STIs, such as syphilis and hepatitis B, is also usually recommended.
- ICTCs in government hospitals provide free, confidential testing and counselling.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This answer cannot tell your HIV status. Testing at the right times gives the answer.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Which HIV test did I have, and what is its window period?
- When should I repeat the test?
- Should I be tested for other STIs?
- Can I speak with a counsellor about my anxiety?
When to seek help
Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.
Emergency — call 112 now
- Call 112 or go to the nearest emergency department if you have a new exposure within the last 72 hours, to ask about PEP, or if you have thoughts of harming yourself.
Book an appointment soon
- See a doctor within a few days if you develop fever, rash, sore throat or swollen glands after the exposure.
Raise it at a routine appointment
- Book repeat HIV tests at about six weeks and three months after the exposure.
