Antigen tests are rapid diagnostic tests that detect the presence or absence of the antigen in the person's body. One of its applications is the detection of SARS-CoV-2, the virus that causes COVID-19. This type of test should be performed during the first 7 days after infection, since this is when the viral load is at its highest.
The sample for subsequent analysis is generally taken nasal (the test will indicate whether it is a nasal test or a saliva test) since the viral load in nasopharyngeal secretions is higher than in saliva. It is important to carry out the test by carefully following its instructions.
The antigen tests that we have at lafarmaciaonline.com comply with the recommendations of the European Union: minimum specificity of the test of 97% and minimum sensitivity of the test of 90%.
