STEP TWO Specimen Collection & Handling

1
Insert the swab to shallow nasal area (not more than ¾ of an inch or 1.5 cm) and slowly rotate at least 6 times against nostril wall.
2
Using the same swab, repeat step #1 in your other nostril.
3
Transfer the swab to the sample tube containing diluent solution (lysis buffer).
4
Using the swab, slowly stir the lysis buffer for at least 6 rotations.
5
Leave the swab in the sample tube for 2 minutes. (show times and swabs in tube)
6
Remove the swab from the tube and dispose of it properly.
7
Place the cap/dropper on the sampling tube.

STEP THREE Testing

1
Open the pouch, remove the test cassette, and place on a clean disinfected flat surface.
2
Set timer for 15 minutes.
3
Apply 4 drops from the sampling tube to the center of the sample well (labeled with an “S”) on the cassette. Apply the drops slowly so that the liquid gets absorbed and doesn’t overflow.
4
Start the timer. Read results at 15–20 minutes. Do not read after 30 minutes. Despite results being visible for up to 24 hours, results are invalid after 30 minutes.
5
Properly dispose of the used test cassette, sample tube, and nasal swab as medical waste.

STEP FOUR Results

1
This test contains a built-in control feature (C line) that develops after adding the specimen and sample diluent. Depending on the intensity of the line, results may be visible up to ~24 hours, but results are best at 15 minutes. If no C line or only the T line appears, the test is considered invalid (you will need to retest with a new test kit).
2
NEGATIVE RESULT: If only the C line is present, the absence of black color in test lines (T) indicates that no COVID-19 virus antigen is detected. The result is negative.
3
POSITIVE RESULT: In addition to the presence of C line, if the T line develops, the test result indicates that COVID-19 virus antigen is detected. The result is SARS-CoV-2 virus positive.
4
Samples with positive results should be confirmed with alternative testing method(s) and clinical findings before a diagnosis is made.
5
INVALID: If no C line develops, the assay is invalid regardless of black color in the test lines as indicated below. Repeat the assay with a new test kit.
