Sample collection in USA

Laboratory testing for the respiratory coronavirus disease 2019 (COVID-19) and the associated SARS-CoV-2 virus includes methods that detect the presence of virus and those that detect antibodies produced in response to infection. Detection of antibodies, called serology, can be used both for clinical purposes and population surveillance. As of March 2020, most countries have limited virus testing to vulnerable individuals, so it is not possible to reliably calculate the prevalence of the virus. Detection of the virus is frequently done by real time reverse transcription polymerase chain reaction (rRT-PCR) method on respiratory samples obtained by various methods, including nasopharyngeal swab or sputum sample. Blood test to detect antibodies produced by the body as a result of an infection is under development. Chest CT scans can sometimes help identify and characterize lung pathology, and have yielded non-specific findings with COVID-19 infection. Some countries have drive-through testing where samples are taken from suspected individuals by a healthcare professional using appropriate precautions.
