If the HIV antibody is confirmed to be positive, it indicates that the person has been infected with HIV. Because it usually takes 2 weeks to 3 months for the human body to produce enough antibodies after HIV infection, some people can be as long as 6 months. This period from HIV infection to antibody detection is called "window period". At this time, although HIV has been infected, there are no symptoms, so it is contagious to others. Some patients with a long window period will have "false negative" test results, so they should be reexamined after 3-6 months. If they are still negative, they can be confirmed not to be infected.

HIV antibody detection is divided into two steps: general test (primary screening) and confirmation test. Only those who are proved to be positive by confirmatory tests are truly HIV antibody positive. HIV antibody-positive people, if asymptomatic, belong to those with the virus, and there is still a long incubation period from the clinical symptoms of AIDS. In view of this, some high-risk groups of AIDS, such as those who have a history of extramarital behavior, have multiple sexual partners, homosexuals, intravenous drug users, illegal blood donors, those who have used untested blood or blood products, those with sexual history, spouses and children of AIDS patients, should be tested for HIVA antibody as soon as possible. In order to curb the spread of HIV, HIV antibody testing should also be listed as a compulsory item for blood donors. If the above-mentioned subjects are HIV-positive, they should not be afraid of medical treatment, and should actively cooperate with doctors in time to prolong the onset and life span. At the same time, positive people should also be responsible to their families, others and society, and cut off all transmission channels under the guidance of doctors to prevent HIV from spreading.
