The update of the standard on the National Testing Strategy for SARS-CoV-2, released by the General Directorate of Health (DGS), indicates that these rapid antigen tests of the self-test type(nasal harvest) must still be carried out “under the supervision of a professional from the entity or establishment..whenever the number of participants/spectators is greater than 1,000, in an open environment, or greater than 500, in a closed environment”.

The DGS also explains that in cultural events "whose ticket sales have already started" at the date of the updated standard, whenever the number of spectators corresponds to that indicated, "it is recommended that the promoter assess the possibility of carrying out laboratory screenings ”. The standard also defines that tests for Covid-19 are now recommended in family events with more than 10 people, such as weddings and baptisms, public services and companies.

The health authority also recommends regular testing in the work context, in places with greater risk of transmission, such as farms and the construction sector, every 14 days, a frequency that should also be applied in public services and workplaces with 150 or more workers, regardless of their employment relationship, type or nature of the legal relationship. Positive results in rapid antigen tests must be confirmed by PCR tests within 24 hours, “in order to ensure the implementation of adequate and proportional Public Health measures, assuming the result obtained in the TAAN [Nucleic acid amplification test , PCR] as valid”, indicates the DGS.
