Croatia to start serology testing for COVID-19 next week

Capak told the national broadcaster HTV that the performance of the survey should take 10 to 14 days to provide a wider insight into the situation.

Experts at the institute and Zagreb's hospital for infectious diseases are making preparations for the testing so that they can establish how reliable serological tests would be.

Serological surveys are often used by epidemiologists to determine the prevalence of a disease in a population. These surveys are sometimes performed at random, anonymous sampling from samples taken for other medical tests or to assess the prevalence of antibodies of a specific organism or protective titre of antibodies in a population.

Capak thinks that yet not enough number of Croatians are immune to this infection to provide for "collective protection" against this novel virus. However, this will change for the better later, according to his explanation.
