It is possible for a negative HIV test to turn positive four weeks after a patient has had high-risk sex.
A negative test result within 4 weeks after high-risk sex does not exclude a positive test result after 4 weeks. This is because a negative test result may occur if the body does not produce enough antibodies before the 4-week period, and a positive test result may occur after the 4-week period when the antibody titer has increased.
After being diagnosed with HIV, patients are advised to seek treatment at a regular hospital. As long as they receive standardized and effective treatment, HIV can be controlled, allowing them to live a normal life.
In addition, AIDS is a more serious disease, once the disease progresses, there is no cure, so patients need to pay attention to early treatment.
