V-Chek Sars-CoV-2 Rapid Ag Test is a rapid chromatographic immunoassay for the qualitative detection of specific antigen to SARS-CoV-2.

  • Rapid: results within in 15 mins
  • Easy to use
  • Specimen: Nasopharyngeal swab / Nasal Swab / Oropharyngeal
  • Visual interpretation of results
  • Early diagnostics, early medical treatment and reduce the closed contacts
  • High specificity, more than 95%
  • Good coincidence rate with RT-PCR test, especially for samples that with Ct value less than 25
  • Ideal testing tools for on-site test and places that with limited access to RT-PCR laboratory significantly improve the detection capability

This reagent uses double-antibody sandwich to legally detect the antigen of novel coronavirus (SARS-CoV-2) in nasopharyngeal swab and oropharyngeal swab samples. During detection, the gold labeled anti-SARS-CoV-2 monoclonal antibody in the labeling pad binds to the SARS-CoV-2 antigen in the sample to form a complex, and the reaction complex moves forward along the nitrocellulose membrane under the action of chromatography, It is captured by the anti-SARS-CoV-2 monoclonal antibody pre-coated by the detection zone (T) on the nitrocellulose membrane, and finally a red color reaction line is formed in the T zone. If the sample does not contain SARS-CoV-2 antigen, a red color reaction line cannot be formed in the T zone. Regardless of whether the sample to be tested contains SARS-CoV-2 antigen, a red reaction line will always form in the quality control area (C).
