The COVID-19 Antigen Saliva Test kit is a lateral flow immunoassay intended for the preliminary screening and qualitative detection of nucleocapsid protein antigen from severe acuterespiratorysyndrome coronavirus SARS-CoV-2which causesthe Coronavirusdisease(COVID-19),in direct saliva sample from individuals suspected of coVD-19 by their healthcare provider within the first seven days of symptom onset.The COVID-19 Antigen Saliva Test kit is for professional use only and is intended to be used as an aid in the diagnosis of SARS CoV-2 infection.
SARS-CoV-2is anenvelopedsingle-stranded RNAvirus ofthe Baenus COVD-19 is an acute respiratory infectious disease. People are generally susceptible.Currently. the patients infected bytheSARS-CoV2are the main source ofinfection:asvmptomatic infected peope car also be an infectious source Based on thecurrentepidemiologica investigation, the incubation period is 1to 14 daysmostly 3to 7 days The main manifestations include feverfatigue and drycough.Nasa congestion, runny nosesore throatmyalgia and diarhea are found in a few cases.
Results are for the identification of SARS-CoV-2 nuceocapsid protein antigen. The SARS-CoV-2 antigen is generally detectable in upper respiratory specimens during the acute phase ofinfectionPositive results indicate the presence of SARS-CoV-2viralantigenshowever cinicai corelation with patient history and other diaanostic information is key to determine status of infection.Positive results don't preclude bacterialinfection or co-infection with other yiruses.eaatveresuts To patients with symptom onset for more than seven days should be treated as presumptive and confirmation with a molecular assayand patient management may be performed according to local regulations as needed.
