When should I get HIV tested?
It’s recommended that you test for HIV and other sexually transmitted infections (STIs) at least once a year if you’re having sex, even if you always use protection. You might want to test more regularly than this, for example, if you are having sex with a new partner or feel you are more at risk.
What is the best time to test for HIV after exposure?
One recommended strategy is to get tested 2-4 weeks, 3 months, and 6 months after a risky exposure. Using a sensitive antigen/antibody HIV test, of those who are infected, most will test positive at 1 month; almost all will test positive at 3 months; and the rest will test positive at 6 months.
What is the maximum window period for HIV?
The median window period is 31 days (interquartile range 26 to 37 days). This indicates that half of all infections would be detected between 26 and 37 days after exposure. 99% of HIV -infected individuals would be detectable within 57 days of exposure.
Is a negative HIV test at 6 weeks conclusive?
If your HIV test is negative, and more than 6 weeks has passed since your last risk (eg unprotected sex), you are HIV negative and no further testing is required.
How long can you stay undetectable?
A person’s viral load is considered “durably undetectable” when all viral load test results are undetectable for at least six months after their first undetectable test result. This means that most people will need to be on treatment for 7 to 12 months to have a durably undetectable viral load.
Can I test positive while on PEP?
After a course of PEP you need to wait 28 days before testing for HIV. This is because PEP can delay infection.
