About 1 in 7 Americans who have HIV don't know it. The CDC recommends that everyone between ages 13 and 64 get a test at least once. If you fall into a high-risk category -- perhaps you have multiple sex partners, have used injectable drugs, or have a partner who is HIV positive -- then you ought to test regularly (ideally every 3 to 6 months). Free tests can be a huge help.
HIV tests are now relatively easy to get and fairly affordable. You can even buy an FDA-approved at-home oral HIV test called OraQuick for around $40 at many drugstores or online. But if money is tight or you need to test often, a free HIV test is the way to go.
Before getting an HIV test, keep these things in mind:
Combination tests look for both HIV antibodies and a protein (or antigen) called p24. If you have HIV but your body hasn't made antibodies yet, you'll have high levels of p24. Nucleic acid tests look for the HIV virus in the blood.
There are pros and cons to each type of test, so pre-test counseling may be helpful. Most clinics and community centers that offer free HIV tests also offer counseling. Some locations offer all the different types of HIV tests or just one of them. Whatever test you get, it is likely to be accurate as long as you take it at the right time. Accuracy rates are around 99% to 100%.
When you test matters. Getting your test at the right time is more important than the type of free HIV test you get. It takes a little while for detectable signs of HIV to show up in your bloodstream. Some tests can be positive as early as 10 days after exposure. Other tests (antibody tests) can take months. You might not test positive for 3 to 6 months after the virus gets in your body.
Depending on the timing, you may need to do several tests to confirm the results. If you had a very recent (less than 72 hours ago) possible exposure to HIV, it's too soon for a test. But it's exactly the right time to talk to a doctor about starting PEP (post-exposure prophylaxis). That's a medication that can prevent you from getting HIV in the first 72 hours after unprotected sex, risky drug use, or other possible exposure.
