CO-Check COVID-19 Rapid Antigen Test is a lateral flow immunoassay intended for the qualitative detection of Nucleocapsid antigen from SARS-CoV-2 in nasal or nasopharyngeal swab from individuals who show COVID-19 symptoms. It can also be used as a screening test in asymptomatic patients who are suspected to be infected by COVID-19
It is a 15- minute testing you can perform anytime and anywhere

How to be test?
*Pink / Purple line appears in both the "C" and "T" region
Protein antigen of the SARS-CoV-2 virus were found in your sample.
*Pink / Purple line appears in only the "C" region
Protein antigen of the SARS-CoV-2 virus were not found in your sample.
*No Pink / Purple line in the "C" region
The test is unable to determine whether there are proteins antigen of the SARS-CoV-2 virus or not. A new test is needed.
