How to determine the window period for HIV nucleic acid testing? During the window period of HIV nucleic acid testing, this diagnosis is effective

At present, a common sexually transmitted disease is called AIDS. AIDS is rarely encountered. Once infected, you must go to a regular hospital for examination and treatment. Generally, there is no difference between the main performance of AIDS in the window period and cold and fever, so many people will be misdiagnosed as influenza. Generally, the window period of AIDS detection is not obvious, which requires detailed repeated testing to judge.

In the window period, the blood test of people infected with AIDS virus could not detect AIDS virus antibody, and the result was negative. The length of the window period was different among individuals, ranging from 2 weeks to 8 weeks, generally 8 weeks, and only very few people had a window period of 3-6 months.

Suggestion: It is recommended to go to a regular hospital for systematic examination and symptomatic treatment after diagnosis

The window period refers to the period from the onset of HIV infection to the production of antibodies in the body that can be detected using current routine testing methods. Usually 3 months, a few may take longer. HIV infected individuals in the window period also have infectivity. Therefore, it is recommended to conduct regular testing with an interval of 3-6 months; The test results during the window period are usually negative. In the early stage of AIDS virus (HIV) infection, about 50%~70% of infected people will have acute symptoms. Usually occurring 1-2 weeks after infection, symptoms such as fever, sore throat, headache, diarrhea, fatigue, and weakness appear, which are not significantly different from common colds and fever., It lasts for about 2-4 weeks, and can improve itself and enter the incubation period of AIDS. It is difficult to determine whether AIDS virus infection is excluded by symptoms alone. Other reasons can also cause it. The window period of AIDS is 14-90 days.
