CerTest SARS-CoV-2 (Ag-Nasal Sample-Self Test) is a test for self-testing for lay users.

CerTest SARS-CoV-2 (Ag-Nasal Sample-Self Test) is a coloured chromatographic immunoassay (one step assay) for the qualitative detection of nucleoprotein (N) antigen of SARS-CoV-2 from human nasal swab samples from patients suspected of COVID-19 infection. It offers a simple and a highly sensitive screening assay as an aid in the diagnosis of SARS-CoV-2.

The test is for in vitro diagnostic use only. This test can be used for non-prescription home use (self-testing) with nasal swab samples.

An unseen pneumonia spread swiftly in Wuhan, China, in December 2019. Scientists sequenced and recognized a novel β-coronavirus. The disease, caused by the Severe Acute Respiratory Syndrome Corona Virus 2 (SARS-CoV-2), is called as Coronavirus disease 2019 (COVID-19).

Clinical forms of this disease comprise from mild to very severe symptoms: pneumonia, fever and respiratory symptoms are the most frequent. Other symptoms of viral infection include a sore throat, aches, pain, and shortness of breath. In some cases, runny nose, nausea, and diarrhoea also occur.

The outbreak of newly discovered coronavirus begins mainly via discharge from the nose or droplets of saliva, once an infected individual sneezes or coughs, and the estimated time for incubation is within 2 weeks.
