ABSTRACT
Diagnostic tests to detect the coronavirus allow the identification of the virus in addition to the antibodies generated by the body of the person who has previously been infected, so the objective of the research is to detect COVID-19 in diagnostic tests carried out in patients. It is a quantitative, descriptive experimental cross-sectional study, which was carried out with a total population of 560 patients from hospital centers. In its results, we observed that 83.4% (n=467) of patients were non-reactive to the Antigen Test and 66.8% (n=374) of patients were negative in the PCR test. In conclusion, the strengths of the COVID-19 detection tests should be complemented since it allows for an accurate and timely diagnosis of patients. © 2022 The Authors.
