This may be the least known and most interesting fact that people don't know about HIV testing. There's an at-home test* for HIV that you can purchase online at Orasure.com or, to find the test at a pharmacy near you, use the store locator.
The test is only $39.99, compared to some HIV screenings at your local health care provider which can cost up to $75. This makes checking yourself for HIV efficient and more private.
Other alternatives to getting tested at the doctor's office or at home include free tests at non-government organizations, community-based organizations or health departments. You can find the free testing location closest to you by visiting hivtest.cdc.gov.
*Much like at-home pregnancy tests, it is possible to receive a false negative or false positive. For this reason, if there is probable cause to believe that you may be infected with HIV, seek the help of a healthcare professional to receive proper diagnosis and treatment.
