CO-Check COVID-19 Rapid Antigen Test is a lateral flow immunoassay intended to be used as an aid for diagnosis by the qualitative detection of nucleocapsid antigen from SARS-CoV-2 in nasal swab from symptomatic individuals who are suspected of COVID-19 infection within 7 days of symptom onset.

Results are for the identification of SARS-CoV-2 nucleocapsid antigen. Antigen is generally detectable in nasal swab 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. Positive results do not rule out bacterial infection or co-infection with other viruses. The agent detected may not be the definite cause of disease. Negative results do not rule out SARS-CoV-2 infection and should not be used as the sole basis for treatment or patient management decisions. Negative results should be considered in the context of a patient's recent exposures, history and the presence of clinical signs and symptoms consistent with COVID-19, and confirmed with molecular assay, if necessary, for patient management.

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.

We aim for maximum accuracy, for your peace of mind
