Principle The COVID-19 Ag Rapid Saliva Test Device uses double antibody sandwich immunoassay. The NC membrane pre-immobilized with monoclonal antibodies against SARS-CoV-2 antigen and anti-mouse polyclonal antibodies, and the colloidal-gold conjugated with monoclonal antibodies specific to SARS-CoV-2 antigen. If SARS-CoV-2 antigen present in the sample, a complex formed between the anti-SARS-CoV-2 conjugate and the antigen will be caught by the specific anti- SARS-CoV-2 monoclonal coated on the T region. Results appear in 10 to 20 minutes in the form of a red line that develops on the strip. Whether the sample contains the SARS-CoV-2 antigen or not, the solution continues to migrate to encounter another reagent (an anti-mouse IgG antibody) that binds the remaining conjugates, thereby producing a red line on the region C. Kit Content 1) Test device (individually packed in a foil pouch with desiccant). 2) Instruction for use. Materials required but not provided Timer Precautions • For in vitro diagnostic use only. • Do not re-use the test device. • Do not use after the expiration date. • Do not use the test kit if the pouch is damaged or the seal is broken. • Perform test at room temperature 15 to 30°C. •Wear gloves when hanging the samples, avoid touching the reagent membrane and sample window. • All samples and used accessories should be treated as infectious and discarded according to local regulations. • Avoid using blood samples.
