A negative test 8 weeks after high-risk behavior does not rule out AIDS.
AIDS has a window period, that is, a period of time when the body has not produced enough antibodies after infection with HIV. AIDS window period is generally 12 weeks, and 8 weeks has not exceeded the upper limit of the window period of AIDS, so 8 weeks after high-risk behavior check AIDS antibody is negative, can not rule out infection, need to be 12 weeks after high-risk behavior and then test again, if the results are still negative, basically can be ruled out all AIDS infection.
AIDS is an infectious disease caused by human immunodeficiency virus infection, mainly destroying the human immune system, inducing a variety of diseases, including a variety of serious infections and tumors, such as oral candidiasis, Kaposi’s sarcoma, and so on, and the serious case will endanger the patient’s life.
Most patients can produce HIV antibodies in their blood about 6 weeks after HIV infection, at which time HIV antibodies can be detected as positive by blood test, but due to individual differences in the length of the window period, it is generally necessary to exceed the upper limit of the window period to conduct the test again. If both tests are positive, the diagnosis of HIV infection can be confirmed.
After high-risk behavior, you need to go to a regular hospital to get a clear diagnosis.
