COVID-19 Ag test ,( SARS-CoV-2) antigen Rapid Test is for the rapid, qualitative detection of the nucleocapsid protein antigen from SARS-CoV-2 in human nasal swab,oropharyngeal swab or nasopharyngeal swab specimen. The test is for in vitro diagnostic use only.
The benefit of having a SARS-CoV-2 Antigen test available
The SARS-CoV-2 virus causes respiratory tract infection. It is transmitted mainly via respiratory droplets after close contact, and primary viral replication is presumed to occur in mucosal epithelium of the upper respiratory tract (nasal cavity and pharynx)1 . At these locations viral load peaks within the first week after symptom onset, and then declines2 .
A SARS-CoV-2 antigen test detects the presence of the SARS-CoV-2 virus from part of the upper respiratory tract swab specimens by identifying a nucleoprotein that is carried by the virus. The test identifies current infection during the acute phase of COVID-19, while the virus is still present in large quantities in the respiratory tract.
Features and benefits of the SARS-CoV-2 Antigen Rapid Test
Besides laboratory PCR testing, antigen assays can also be offered as rapid testing in near-patient settings. The SARS-CoV-2 Rapid Antigen Test is a rapid chromatographic immunoassay intended for the qualitative detection of specific antigens of SARS‑CoV‑2 present in the human nasopharynx. This test is intended to detect antigen from the SARS‑CoV‑2 virus in individuals suspected of COVID‑19. This product is strictly intended for professional use in laboratory and Point of Care environments. Similar to laboratory instruments, it detects a SARS-CoV-2 antigen, the nucleoprotein.
