Screening Tests in the Era of COVID-19: Implications for the Plastic Surgeon

Summary: The novel coronavirus, severe acute respiratory syndrome coronavirus 2, responsible for the coronavirus disease of 2019 (COVID-19) pandemic, has claimed over 2 million lives to date and brought the global economy to a halt, including elective surgery. As the authors emerge from lockdown, new protocols must be implemented to minimize risk by means of appropriate screening of their patients, surgical adjustments to reduce viral transmission in case of undiagnosed infection, and the development of accurate severe acute respiratory syndrome coronavirus 2 tests while awaiting the distribution of an effective vaccine. Many serology and molecular tests have received emergency use authorization from the U.S. Food and Drug Administration, but they have not yet been independently verified. There are three main types of diagnostic tests available: (1) imaging studies, (2) molecular tests, and (3) serology tests. Imaging studies reveal bilateral lower lobe pneumonia and ground-glass opacities that are suggestive of disease. Quantitative reverse transcription polymerase chain reaction identifies specific segments of viral RNA, indicating the active presence of the virus in the test subject, which is most useful for elective surgery screening. Finally, serology studies detect the presence of immunoglobulin M and immunoglobulin G antibodies to the virus, indicating a current or past infection. Each test offers its own benefits and limitations.
