COVID-19 & Influenza A/B Antigen Combo Test Kit , Influenza A/B
Rapid , Test Kit
Product Description
REAGEN This kit is used for in vitro qualitative detection of COVID-19 &
Influenza A/B antigen in human oropharyngeal swabs and
nasopharyngeal swab samples.
Mechanism Of Reaction
REAGEN This kit adopts the detection principle of double antibody
sandwich method. The binding pad of the detection card contains
colloidal gold-labeled mouse N protein monoclonal antibody I; the
detection line (T&A/B line) of the nitrocellulose membrane is
coated with mouse N protein monoclonal antibody Antibody II,
quality control line (line C) is coated with goat anti-mouse
antibody.
The collected samples are processed by the sample extract and
added. During the test, when the extract containing the N protein
of the COVID-19 & Influenza A/B is added to the sample hole of the
test card, under the action of chromatography, the sample moves to
the end of the absorbent paper and first passes through the binding
pad. The N protein and colloidal gold labeled mice The source N
protein monoclonal antibody I specifically binds and continues to
move to the absorbent paper end. When the sample moves to the
T&A/B line, the N protein bound to the labeled antibody
specifically binds to the N protein monoclonal antibody II coated
in the T&A/B line in a double antibody sandwich mode, and stays
at the T&A/B line; the remaining liquid continues to absorb
water The paper end moves. When it moves to the C line, the mouse N
protein antibody I labeled with colloidal gold specifically binds
to the goat anti-mouse antibody in the C line. The T&A/B line
shows a red band, indicating that the COVID-19 & Influenza A/B
antigen is positive. No matter whether the T&A/B line is
colored or not, the C line should show red. If the C line is not
colored, the test is invalid and the sample needs to be tested
again.
Interpretation Of Results
Negative: A purple-red band, only the quality control line (C line) is
colored.
Positive: Two purple-red strips, the detection line (T&A/B) and the
quality control line (C line) are both colored .
Precision
REAGEN The sensitivity of the test kit was 95.5%, the specificity was
98.3%, and the accuracy was between 90%-99.0%.
