Under normal circumstances, HIV infection is divided into several stages: window period, incubation period, and onset period. The specific time of the incubation period varies from person to person. When the human body is infected with AIDS, how long it takes to be detected is a very important question. In other words, how many weeks does a normal person produce HIV antigen?
Normal people cannot be diagnosed with AIDS. If it is a normal person, it will not produce blood AIDS antibodies without HIV infection. Therefore, no matter when it is checked, the AIDS antibody is negative. However, if you are infected with HIV, you can usually check for AIDS antibodies in your blood within 2-4 weeks, and you can get blood AIDS antibody positive.
Generally speaking, high-risk behaviors can be found in the blood within two weeks at the earliest. However, since the time of AIDS antibody production is related to personal physical conditions, it is generally considered The AIDS test window period is half a year. If the blood test for AIDS antibody is positive within six months, and the confirmation test is also positive, the diagnosis of AIDS can be confirmed.
However, if the HIV test result is negative within half a year, then HIV infection is not considered, but the possibility of HIV infection cannot be completely ruled out. At present, the detection methods for HIV infection have been progressing, and the window period has been significantly shortened. For example, DNA and RNA testing only takes a few days; the fourth-generation antigen antibody test requires about two weeks; the third-generation antibody test requires about three weeks.
