Tigsun COVID-19 Antigen Rapid Test is used for the qualitative detection of the COVID-19 antigen in human nasopharyngeal swab and oropharyngeal swab samples. The antigen detection kit detects the novel coronavirus N protein antigen, which can be detected in the early stage of viral infection and can be used as direct evidence of viral infection. It can be used as an auxiliary diagnostic index in clinical practice.

        Tigsun COVID-19 Antigen Rapid Test (Lateral Flow Method) is based on the principle of immunochromatography to determine the SARS-CoV-2 antigen in human nasopharyngeal swab and oropharyngeal swab samples.

        The main infection site of the SARS-CoV-2 is the lower respiratory tract. The incubation period of infection is variable. Common symptoms after infection with SARS-CoV-2 include respiratory symptoms, fever, cough, shortness of breath, and difficult breathing. In more severe cases, infection can cause pneumonia, severe acute respiratory syndrome, kidney failure, and even death.
