The COVID-19 (SARS-CoV-2) RNA by PCR test is a diagnostic test used to detect the presence of genetic material (RNA) from the SARS-CoV-2 virus in respiratory specimens, typically collected via nasal or throat swabs. The test is critically important because it is the gold standard for diagnosing COVID-19 infection, enabling early identification, isolation, and treatment of cases, supporting public health responses, monitoring disease spread, and contributing to efforts aimed at controlling and mitigating the impact of the COVID-19 pandemic.
