Even if a person with AIDS is on medication, AIDS can still be detected, whether by drawing blood or using test strips. Even if the virus cannot be detected in the blood, the patient’s antigens and antibodies can still be detected in the blood by drawing blood or using test strips, and the diagnosis can be confirmed by testing for AIDS antigens and antibodies. Generally, antibodies to AIDS can be detected in the blood 3-4 weeks after infection, and antigens can be detected in the blood 2-3 weeks after infection, so the results of combined antigen-antibody testing are relatively accurate, and testing with test strips or other methods is also possible.
