Chemiluminescence for antigens is usually ruled out at 3 to 4 weeks. Chemiluminescence is categorized into third-generation antibodies and fourth-generation antibody-bound antigens, which can generally be ruled out if the test is negative after 4 weeks. For the fourth generation antibody-binding antigen test, if the test result is negative after about 3 weeks, this possibility can be ruled out. AIDS is diagnosed primarily by testing for AIDS antibodies or nucleic acids, and there is no way to infer whether or not you have AIDS infection from your symptoms. Since the production of antigens precedes the production of HIV antibodies, the test results are often more accurate through two-way antigen-antibody testing. In addition, if HIV infection is suspected, consider a blood test or an HIV test strip. If the test is positive after the window period, the diagnosis is basically confirmed and systematic and standardized anti-HIV treatment is required. Anti-HIV treatment is the most effective measure to treat AIDS, and requires long-term medication as prescribed by the doctor, such as nucleoside reverse transcriptase inhibitors.
