Rapid chromatographic immunoassay for the qualitative detection of SARS-CoV-2 antigens present in human nasopharynx. Rapid-VIDITEST COVID-19 Antigen is a rapid chromatographic immunoassay for the qualitative detection of SARS-CoV-2 antigens in nasopharyngeal swab specimens from individuals with suspected SARS-CoV-2 infection in conjunction with clinical presentation and the results of other laboratory tests.Results are for the detection of SARS-CoV-2 Antigens. An antigen is generally detectable in upper respiratory specimens during the acute phase of infection. Positive results indicate the presence of viral antigens, but clinical correlation with patient history and other diagnostic information is necessary to determine infection status. Rapid Tests: Rapid-VIDITEST tests are one step immunochromatographic assays for qualitative detection of a variety of viral and bacterial antigens in human samples. Depending on the specified antigen the specimens are taken as nose/throat swabs, lavages, aspirations, urine and stool samples: ?Simple use ? Result within 15 minutes ? Easy interpretation ? Laboratory equipment not needed CE-IVD certified.
