Description
Lateral flow immunoassay method for the qualitative detection of SARS-CoV-2 nucleocapsid antigen in nasal swab of subjects with symptoms or other epidemiological reasons suggesting COVID-19 infection.
The test is intended for use by non-professionals aged 15 and, as appropriate, by adults to test another subject under 15. Individuals over the age of 65 must seek assistance in performing the test.
The test provides only a preliminary screening result for the SARS-CoV-2 virus. Positive results must be confirmed by a laboratory PCR test.
People with a negative test result who continue to experience symptoms similar to those of COVID-19 should see their doctor.

How to use
Test preparation
Make sure all test components are at room temperature (15-30 ° C).
Have a watch, timer, or stopwatch handy.
Check that the package is intact. Do not use the test if the package is visibly damaged.
Open the test cassette package only at the time of use. Use the test cassette within one hour of opening the package.
Wash your hands with soap and water and dry them thoroughly.

Carrying out the test
Open the tube containing the Extraction Reagent by carefully removing the film. Insert the tube into the tube holder (hole on the package).
Remove the swab from the bag: open the package from the end of the stick. Do not touch the swab head. Remove the swab and gently insert the entire swab head into the nostril to a depth of approximately 2.5 cm. Rotate the swab against the wall of the nostril for at least 5 times. Remove the swab, insert it into the other nostril and repeat the same operation. Do this carefully: false negative results may occur if the nasal swab is not performed correctly.
Insert the swab into the tube containing the extraction reagent. Rotate the swab 5 times into the reagent, pressing the swab head against the bottom and side of the tube. leave the buffer in the reagent for 1 minute. Remove the swab by squeezing the sides of the tube so that the liquid comes out of the swab. Close the tube tightly with the cap.
Open the sealed pouch containing the Test Cassette and remove it. Place the test box on a flat surface.
Hold the tube vertically over the sample well and add 3 drops into the well, gently squeezing the sides of the tube. A false negative result may occur if fewer than 3 drops of sample are added to the well. The result will not be affected if an additional 1-2 drops of sample are added, provided that the control line (C) can be read.
Start the clock / stopwatch or timer. Read the test result after 15-20 minutes, do not read the result if more than 20 minutes have passed. Incorrect results may occur if the test results are read before 15 minutes or after 20 minutes.
After testing, collect the used kit parts and swab samples in a disposal bag and dispose of them with household waste. Wash hands thoroughly after handling.

Interpretation of results
- POSITIVE: two lines appear, the control line (C) and the test line (T). The color intensity of the test line (T) can be very weak, the result is however to be interpreted as positive. A positive test result indicates that you probably are
