The Covid-19 rapid antigen test is a rapid immunochromatographic nasopharyngeal swab for the qualitative detection of Sars-CoV-2 antigens present in the human nasopharynx. For professional in vitro diagnostic use only. The Covid-19 Rapid Antigen Test (Nasopharyngeal swab) is a rapid immunochromatographic test for the qualitative detection of Sars-CoV-2 antigens present in nasopharyngeal swab samples. The results detect Sars-CoV-2 antigen. The antigen is generally found in swabs of the upper respiratory tract during the acute phase of the infection. Positive results indicate the presence of viral antigens, but a clinical correlation with the patient’s medical history and other diagnostic information is required to determine the infectious state. The positive results do not exclude bacterial infection or co-infections with other viruses. s. The identified agent may not be the determining cause of the disease. Negative results do not exclude SARS-CoV-2 infection and should not be used as the sole basis for therapy or other patient management decisions, including infection control. Negative results should be treated as preliminary and confirmed by a molecular test if necessary for patient management. Negative results should be evaluated in conjunction with recent exposures, patient history, and in the presence of clinical signs and symptoms consistent with SARS-CoV-2. The new coronavirus (SARS-CoV-2) belongs to the β genus. COVID-19 is an acute respiratory infectious disease. It mainly affects humans. Patients infected with the new coronavirus are currently the main source of infection; even asymptomatic infected individuals can be a source of infection.
