In more than 97% of people, this period lasts between 2 and 12 weeks.In a very small number of people, the process takes up to 6 months. good strategy would be to go back for a test 3 months after your possible exposure; the result you get after 3 months will be 99% certain.

Diagnosis of HIV/AIDS Most people develop detectable antibodies approximately 30 days after infection, although some seroconvert later. The vast majority of people (97%) have detectable antibodies by three months after HIV infection; a six-month window is extremely rare with modern antibody testing. During the window period, an infected person can transmit HIV to others although their HIV infection may not be detectable with an antibody test.

- There are different types of HIV Tests, and each type has a different window period. We have a more in depth article about HIV test window periods. A test taken at least 12 weeks (3 months) after exposure to the virus provides highly accurate results.

- During this window period, people infected with HIV will not have antibodies in their blood high enough to be detected by an HIV test. Most of the people develop detectable HIV antibodies within 6 to 12 weeks of infection. In very rare cases, it can take up to 6 months also.ntibodies are the body's response to an infection. If a person has antibodies against HIV in his/her blood, it means the person has been infected with HIV. The time between the infection and development of antibodies is called the window period.

HIV/AIDS HIV is most commonly diagnosed by testing your blood or saliva for antibodies to the virus. Unfortunately, it takes time for your body to develop these antibodies — usually up to 12 weeks.hese tests include: 1  CD4 count. 2  CD4 cells are a type of white blood cell that's specifically targeted and destroyed by HIV. 3  Even if you have no symptoms, HIV infection progresses to AIDS when your CD4 count dips below 200. 4  Viral load. 5  This test measures the amount of virus in your blood.

HIV Test Window Periods Antibody tests (Rapid tests) — give a positive result based on antibodies to HIV, not the virus itself. 1  2-8 weeks (up to 2 months) after infection, most people will have enough antibodies to test positive. 2  12 weeks (3 months) after infection, about 97% of people will have enough antibodies to test positive.here's a period of time after a person is infected during which they won't test positive. This is called the “hiv window period.”. The window period can be from 9 days to 3-6 months, depending on the person's body and on the HIV-test that's used.

Comprehensive, up-to-date information on HIV/AIDS treatment and prevention from the University of California San Francisco If someone with HIV is diagnosed with one of these opportunistic infections (even if the CD4 count is above 200), he or she is said to have AIDS. AIDS usually takes time to develop from the time a person acquires HIV--usually between 2 to 10 years or more. Once a person has been diagnosed with AIDS, she or he is always considered to have AIDS, even if that person's CD4 count goes up again and/or they recover from the disease that defined their AIDS diagnosis.

HIV Testing Antibody tests detect the presence of antibodies, proteins that a person’s body makes against HIV, not HIV itself. Most HIV tests, including most rapid tests and home tests, are antibody tests. It can take 3 to 12 weeks for a person’s body to make enough antibodies for an antibody test to detect HIV infection. In general, antibody tests that use blood can detect HIV slightly sooner after infection than tests done with oral fluid.
