Intended Use
COVID-19 Antigen Rapid Test Cassette is for in vitro qualitative detection of specific antigens to SARS-CoV-2 present in human throat or nasal cavity. It cannot be used as the basis for the diagnosis and exclusion of COVID-19.
This reagent is used to detect cases with suspected symptoms of COVID-19 within 7 days. If suspected symptoms are more than 7 days, it is recommended to test with COVID-19 antibodies or nucleic acid reagents.
The main clinical symptoms of COVID-19 are: Fever, dry cough, fatigue, a few patients will have stuffy nose, runny nose and diarrhea.
Principle
This kit uses double antibody sandwich immunoassay to detect specific antigens to SARS-CoV-2 in human throat or nasal cavity. The membrane was precoated with SARS-CoV-2 specific antibody on the test zone and goat anti mouse IgG antibody on the control zone.
During the test, the specimen is allowed to react with SARS-CoV-2 specific antibody-colloidal gold particles conjugate, which was predried on the test. The conjugate binds to the SARS-CoV-2 forming an Antibody~Antigen complex.
Sample Collection
☀ Throat Swab Sample
Take a disposable sampling swab out, insert it into the throat of the patient. Use the swab to gently wipe the pharyngeal tonsils on both sides of the patient for at least 3 times, and then wipe them on the posterior pharyngeal wall for at least 3times. Withdraw the swab from the throat.
☀ Nasal Swab Sample
Take a disposable sampling swab out, insert it into the nostril of the patient. Carefully insert the swab into the nostril. Gently rotating, pushing the swab until meet resistance at the level of the turbinates (less than one inch into the nostril). Rotate the swab several times against the nasal wall then remove it from the nostril.
Interpretation of Results
☀ Positive: One color line in the control zone (C) and one color line in the test zone (T). This indicates that the sample contains SARS-CoV-2 antigen.
☀ Negative: Only one color line in the control zone (C). This indicates that no SARS-CoV-2 antigen has been detected.
☀ Invalid: If no color line appears in the control zone (C), the test is invalid. Discard the test cassette and perform with new cassette.
Limitation
☀ The kit is only used to detect human throat swab or nasal swab.
☀ The accuracy of the test depends on the process of sample collection. Improper sample collection, improper sample storage or repeated freezing and thawing of samples will affect the test results.
☀ The test results of this reagent are for clinical reference only and should not be used as the sole basis for clinical diagnosis and treatment. The clinical management of the patient should be considered in combination with other laboratory tests of the patient's symptoms/signs history and treatment response.
