Antibody test results should not be used to group people together in settings such as schools, dormitories, and correctional facilities; or to exempt someone from screening testing. False-positive results can occur. Occasionally, a person may possess antibodies directed against one microbe, but that cross-react in the laboratory during serologic tests for different pathogens for instance, related microbes. In the case of SARS-CoV-2, additional research is needed to determine what percentage of non-infected individuals might possess cross-reactive antibodies that could lead to these false-positive results.
False-negative tests can occur. Conversely, even in a patient with a true history of infection, it is possible for their blood not to generate a strong enough signal for a positive serology result. Testing and turnaround time may vary from a few hours to days, depending on the workload and throughput of analysers in operation.

There is interest in developing other testing modalities for the confirmation of diagnosis, such as antigen testing and serological assays [ 1 ]. Nevertheless, questions remain regarding the clinical utility of serological testing as a diagnostic tool. Residual sera were collected from this cohort and stored for serological testing. Samples were handled in strict accordance with the WHO biosafety precautions as previously described [ 3 ]. Patients who were asymptomatic at the time of https://ampeblumenau.com.br/wp-content/uploads/2020/02/archive/uncategorized/hotels-around-disney-world-orlando-florida.php testing for contact screening purposes could not be stratified according to time from onset of illness and were excluded.

If test results show that you have antibodies, it indicates that you were likely infected with COVID at some time in the past. It may also mean that you have some immunity.
But there's a lack of evidence on whether having antibodies means you're protected against reinfection with COVID The level of immunity and how long immunity lasts are not yet known.
