Boson Biotech Rapid SARS-CoV-2 (Covid-19) Antigen Test Kit How does the Rapid SARS-CoV-2 (Covid-19) Antigen Test Card work? The qualitative antibody test is based on a double antibody sandwich membrane: medical device for in vitro diagnosis. The kit is designed to detect SARS-CoV-2 nucleocapsid antigen in patient nasopharyngeal swabs.
SARS-CoV-2 antigens present in the sample react with the anti-SARS-CoV-2 antibody-coated particles in the test cassette.
The mixture migrates up the membrane by capillary action and reacts with the pre-coated antibody in the test line region. To serve as a procedural control, a coloured line will always appear in the control line region, indicating that the appropriate volume of sample has been added and that membrane absorption has occurred.
How is the SARS-CoV-2 Antigen Test (Covid-19) performed?
Use the swab to collect the nasal sample (it is recommended to test both nostrils, rotating the swab 3-5 times inside the nose)
The swab should reach a depth equal to the distance from the nostrils to the outer opening of the ear.
Leave the swab in place for several seconds to absorb secretions.
Open the cap of the tube containing the solution.
Insert the swab into the tube.
Turn the swab inside the tube for one minute.
Tightly close the cap of the tube.
Remove the test from the foil pouch and use within one hour.
Place the test on a clean, level surface.
Use a dropper from the tube to add 3 drops of the reagent sample to the sample well (S) of the test, then start the timer.
Wait for the coloured lines to appear. Read the results after 15 minutes. Do not interpret results after 20 minutes. Interpretation of the Results:
Negative: A coloured line appears in the control line region (C). No line appears in the test region (T).
Positive: Two coloured lines appear. A coloured line appears in the control line region (C) and an adjacent line appears in the test region (T).
Invalid: The control line does not appear. Insufficient sample volume or incorrect procedural techniques are the most likely causes.
Review the procedure and repeat the test with a new test.
