One out of 10 County residents living with HIV is unaware of their status. Everyone should be tested for HIV at least once in their lifetime, and more frequently if they have ongoing risk.

Risk factors include:

  • You are sexually active and identify as gay or bisexual, or are a man who has sex with other men
  • You have an HIV positive partner
  • You have anal sex without using condoms
  • You have multiple sexual or drug using partners whose HIV status is unknown
  • You recently had a sexually transmitted disease
  • You inject drugs and/or share needles with others
  • You exchange sex for drugs, money, housing or other needs

While HIV testing is already free and widely available throughout San Diego County, Getting to Zero seeks to ensure HIV testing is offered during all routine doctor visits.

If you have health insurance/primary health plan talk to them about HIV care. If you do not have health insurance, these clinical providers here have programs/HIV specialists that may help you.

Testing types:

Centers for Disease Control and Prevention testing types

  • Antigen/antibody tests look for both HIV antibodies and antigens. Antigens are foreign substances that cause your immune system to activate. If you’re infected with HIV, an antigen called p24 is produced even before antibodies develop. Tests that detect both antigen and antibodies are recommended for testing done in labs and are now common in the United States. There is also a rapid antigen/antibody test available.
  • Antibody tests detect the presence of antibodies, proteins that a person’s body makes against HIV, not HIV itself. Most rapid tests and home tests are antibody tests.
  • Conventional testing involves getting blood drawn from a vein at a licensed medical professionals office. The sample is then sent to a laboratory and a follow up will be determined based on the blood results. Results are delayed.
  • Same-day tests are antibody tests. The test looks for antibodies to HIV in your blood or oral fluid. Same-day tests that use blood can typically detect HIV sooner after infection than tests with oral fluid. Rapid antibody screening test results are ready 30 minutes or less.
  • Oral fluid antibody self-tests provide rapid results. This requires you to swab your own mouth to collect an oral fluid sample and use a kit to test it. Results are available in 20 minutes.
  • At home collection kits involve pricking your finger to collect a blood sample, sending that sample by mail to a laboratory and call for results as early as the following business day. This test will remain anonymous.

An initial HIV test usually will either be an antigen/antibody test or an antibody test. If the initial HIV test is a rapid test and it is positive, the person will be sent to a health care provider to get follow-up testing. If the initial HIV test is a laboratory test and it is positive, the laboratory will usually conduct follow-up testing on the same blood sample as the initial test. Although HIV tests are generally very accurate, follow-up testing allows the health care provider to be sure the diagnosis is right.


How Soon After Exposure to HIV Can an HIV Test Detect If You Are Infected?

No HIV test can detect HIV immediately after infection. If you think you’ve been exposed to HIV, talk to your health care provider as soon as possible.

The time between when a person gets HIV and when a test can accurately detect it is called the window period. The window period varies from person to person and also depends upon the type of HIV test.
