SARS-CoV-2 detection refers to the methods and techniques used to identify and confirm the presence of the coronavirus that causes COVID-19 in individuals. This area of research involves developing various diagnostic tests, such as PCR tests, antigen tests, and antibody tests, to detect the virus in samples taken from patients. Researchers are also studying new technologies and approaches for more efficient and accurate detection of SARS-CoV-2, as well as exploring the use of biomarkers and other indicators to improve the sensitivity and specificity of diagnostic tests. Effective and timely detection of SARS-CoV-2 is crucial for controlling the spread of the virus and for guiding public health responses to the COVID-19 pandemic.
