In March 2020, the World Health Organization (WHO) declared COVID-19 as a pandemic. Diagnostic and screening tests have been important tools for the clinical characterization of diseases such as COVID-19. This study aimed to analyze the presence of Brazilian manufacturers in the COVID-19 products approved by the Brazilian Health Regulatory Agency (ANVISA). This research used the ANVISA database, in which 329 registered products were identified. We classified them into 4 methods, 3 of which were the object of careful analysis. The results showed Brazil’s external dependence on products from other countries, mainly from China.
