COVID-19 IgG IgM and Influenza A&B antigen Sealing Tube Test Strip Colloidal Gold
INTENDED USE
Amazing COVID-19 Ag/Ab IgG/IgM and Influenza Ag AB Sealing Tube Twin Test Strip is a lateral flow immunochromatographic assay for the simultaneous rapid in vitro differential detection of COVID-19 and Influenza virus.
The kit has two strips. One is for the qualitative detection of COVID-19 nucleocapsid protein antigen and Influenza virus type A in human nasopharyngeal, nasal secretion, saliva or and serum directly collected from individuals suspected of COVID-19 by their healthcare provider within the first seven days of symptom onset.
Another is for the qualitative detection of COVID-19 antibody IgG/IgM in human serum, plasma sodium citrate, sodium heparin, dipotassium EDTA and whole blood sodium citrate, sodium heparin, dipotassium EDTA or fingerstick whole blood and Influenza virus type B in human nasopharyngeal, nasal secretion, saliva or/and serum specimens to aid identifying individuals with an adaptive immune response to COVID-19, indicating recent or prior infection and patients with suspected COVID-19 infection in conjunction with clinical presentation and the results of other laboratory tests.
PRINCIPLE
There are two test strips in the Amazing COVID-19 Antigen IgG IgM Filmseal Tube Twin Test.
COVID-19 antigen test strip is based on sandwich lateral flow immunochromatographic assay highly sensitively detecting COVID-19 nucleocapsid protein in human nasopharyngeal, nasal secretion, saliva or and serum specimens, having an invisible T test zone and C control zone. When the sample is applied into the test tube, the liquid will laterally flow on the surface of the test strip. If there is enough COVID-19 antigen in the sample, a visible T band will appear.
COVID-19 IgGIgM test strip is based on lateral flow immunochromatographic assay highly sensitively detecting COVID-19 IgG and IgM in human whole blood, serum, or plasma specimens, having an invisible IgGT1 zone, IgMT2 zone, and C control zone. When the sample is applied into the test tube, the liquid will laterally flow on the surface of the test strip. If there is enough COVID-19 IgG or and IgM in the sample, a visible IgGT1 or and IgMT2 band will appear in the corresponding area. The C band of two strips should always appear after a sample is applied, indicating a valid result. By this means, the kit can accurately indicate the presence of COVID-19 antigen, IgG, and IgM in the sample.
