Whether negative or positive antibodies are better requires a determination of what kind of antibodies are present and what they do. Different antibodies are judged by different criteria, but in most cases it is considered better to be negative because negative is a condition that is not infected and is normal, while positive may be a condition of infection. However, there are some cases of positive antibodies, which may indicate that the body’s immune function is normal, or that the injected vaccine and other substances are working, which is normal. There are two specific cases: 1. In most cases, a positive antibody indicates the presence of an infection. After infection, the body’s immune system recognizes the infection and produces specific antibodies, making the antibody test positive, such as AIDS antibodies, anti-thyroid antibodies, etc.; 2. This is a normal phenomenon. In addition, some patients may also have positive antibodies during special periods or when they have just been cured of an infectious disease. Therefore, antibody positivity is not the only basis for disease diagnosis. It is recommended that a comprehensive analysis be conducted in conjunction with other test results to clarify the cause of the disease and then treat the symptoms to avoid delaying the disease.
