What does COVID-19 nucleic acid negative antibody positive mean?

Affected by the epidemic, many people now go to local hospitals for nucleic acid testing. However, some people find out why their antigens are positive and their nucleic acids are negative. What the hell is going on here? If this happens, there may be three reasons. The first aspect is caused by the cure after infection. The second aspect is weak positive. The third aspect is caused by novel coronavirus vaccine.

1, cured after infection. During the test, the antibody test result was negative and the body recovered after active treatment. At this time, there is no new coronavirus in the body. At this time, in the process of nucleic acid detection, then the nucleic acid will definitely show negative. So some people are cured after infection, then this phenomenon will occur.

2. Weak positive. If one's own cells apoptosis, then the antigen will also be exposed. In the process of testing, if the test conditions are not ideal and the inspectors do not operate correctly, there is a great chance that the antigen will be positive. However, during this period, the patient does not have COVID-19's disease, so it will naturally be negative during the nucleic acid test.

3. novel coronavirus vaccine. You should know that the vaccine itself is inactivated. The so-called inactivation technology refers to the immune preparation made by pathogenic microorganisms in a special way. If a person is vaccinated, it is likely that the antigen test will be positive during the test. This situation is normal, so don't worry too much.

So is this situation an infection?

In fact, this situation can be regarded as infection or not, and what causes it need to be analyzed in detail? If this phenomenon is caused by a vaccine, it is definitely not an infection; But if it is caused by other reasons, whether it is cured or not, it can be included in the scope of infection.
