This type of test measures antibodies to HIV. The body can take up to three months to produce these antibodies. Most people will have enough antibodies to test positive within three to 12 weeks after contracting HIV. At 12 weeks, or three months, 97 percent of people have enough antibodies for an accurate test result.
According to the Centers for Disease Control and Prevention (CDC), primary HIV symptoms may show up two to four weeks after initial exposure. Symptoms can continue for up to several weeks. However, some people may exhibit the symptoms only for a few days.
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.
It takes longer than this for any symptoms of primary HIV infection to show up. Not everyone who acquires HIV has any symptoms or notices them, but when they do, it’s usually at least one week after exposure and can be several weeks afterwards.
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.
PEP is unlikely to work if it’s started after 3 days ( 72 hours ) and it won’t usually be prescribed after this time. It is best to start taking PEP within 1 day (24 hours ) of being exposed to HIV. PEP makes infection with HIV less likely. However, it’s not a cure for HIV and it doesn’t work in all cases.
Nonetheless, having intercourse for only 10 seconds does give STD germs time to pass from one person to another. So if you get any further symptoms, please go for a check-up at a genitourinary medicine (GUM) clinic.
