The PCR test became deeply embedded in Brazilian and global culture during the COVID-19 pandemic (2020-2023). In Brazil, it was frequently required for travel, employment, and hospital visits. The term 'teste PCR' became ubiquitous in media, healthcare settings, and everyday conversation. While rapid antigen tests became more common for initial screening, PCR tests remained the gold standard for confirmation due to their higher accuracy, leading to the phrase 'confirmar com PCR' (confirm with PCR).
