How to detect and determine the window period of HIV nucleic acid testing?

One of the more common sexually transmitted diseases at present is AIDS. AIDS is rarely encountered, but once infected, you must go to a regular hospital for examination and treatment. Generally speaking, the main symptoms of AIDS during the window period are no different from those of a cold or fever, so many people are misdiagnosed as having the flu. Generally, the window period for HIV testing is not obvious and requires detailed repeated testing to make a judgment.

During the window period, no HIV antibodies can be detected in the blood of HIV-infected people, and the result is negative. The length of the window period varies from individual to individual, ranging from 2 weeks to 8 weeks, generally 8 weeks, and only a very few people have a window period as long as 3-6 months.
