COVID-19 Antigen Test.
It is a direct diagnostic test for the virus that detects structural particles of the virus in respiratory samples (nasopharyngeal swab). The great advantage, in addition to allowing the result to be obtained in just 15 minutes, is that it has a high sensitivity in the first days of the infection. Sampling is nasopharyngeal and it is not necessary to go on an empty stomach.
COVID-19 Antigen Test.
Antibody tests for COVID-19 are available through healthcare providers and laboratories. Check with your healthcare provider to see if they offer antibody tests and whether you should get one.
A positive test result shows you might have antibodies from an infection with the virus that causes COVID-19. However, there is a chance a positive result means that you have antibodies from an infection with a virus from the same family of viruses (called coronaviruses), such as the one that causes the common cold.
