The failure to detect antibodies to AIDS may be due to the fact that the body is not infected with HIV or is in the window period of AIDS, and it is recommended that a retest be conducted three months after high-risk behavior.
If you have engaged in high-risk behavior, but the result of the AIDS-related specific antibody test is negative, there are usually two possible reasons: first, your body is not infected with HIV, so there is no specific antibody production. The second is that the body is in the window period of HIV infection, although the body has HIV infection, but the amount of relevant specific antibody production is not enough to be detected.
After 3 months of high-risk behavior, if the body has HIV infection, the body’s specific antibody production is higher, and the detection rate can be close to 100%. It is recommended that people who have had high-risk behaviors but have been tested negative for HIV should be retested three months later to confirm the diagnosis. Please consult your doctor for details.
