Description
Qualitative membrane-based immunoassay for the determination of SARS-CoV-2 antigens in human oral fluid samples.
Single-use test designed to detect the novel SARS-CoV-2 coronavirus that causes COVID-19 in human oral fluid.
The test is designed for home use with self-collection of oral fluid samples from symptomatic individuals suspected of being infected with the COVID-19 virus.
The test provides a preliminary result only, the final confirmation must be based on clinical diagnostic results.

How to use
Do not put anything in your mouth, including food, drink, chewing gum, or tobacco products for at least 10 minutes before testing.
Wash your hands with soap and water for at least 20 seconds before testing. If soap and water are not available, use a hand sanitizer with at least 60% alcohol.

Sample collection
Remove the funnel and the plastic tube from the packaging, insert the funnel on the tube. Cough deeply 3-5 times.
Note: Wear a face mask or cover your mouth and nose with a cloth while coughing and keep distance from bystanders.
Gently spit the oral fluid into the funnel. The oral fluid (without bubbles) should reach the height indicated by the reference line. If insufficient fluid is collected, repeat the sample collection steps.
Insert the used funnel into the bio-safety bag.

Sample preparation
Place the tube in the plastic holder. Pull to open the buffer solution and pour all the solution into the tube with the oral fluid. Insert the cap on the tube.
Gently squeeze the tube 10-15 times.

Carrying out the test
Remove the test device from the sealed pouch and use it within one hour. The best results are obtained if the test is performed immediately after opening the foil pouch.
Place the test cassette on a flat surface. Invert the tube and pour 2 drops of solution into the well (S) of the test device and then start the timer. Do not move the cassette while the test is running.
Read the results after 15 minutes. Do not interpret the results after 20 minutes.

After completing the test, place all test kit components in the bio-safety bag and dispose of according to local regulations. Do not reuse any of the used kit components.
Wash your hands thoroughly after disposing of the test.

Reading the results
Notify your healthcare provider about the results and carefully follow local instructions / regulations for COVID-19 cases.

- POSITIVE: * two colored lines appear. One colored line should appear in the control region (C) and another colored line should appear in the test region (T). A positive result means that the person is very likely to be infected with COVID-19. Positive samples must be confirmed. Immediately self-isolate as prescribed by local regulations and contact your treating physician or health care district as directed by local authorities. The test will be verified by a confirmatory molecular test (PCR) and instructions on the following steps will be provided.

- NEGATIVE: only one colored line appears in the control region (C). No colored lines appear in the test line region (T). COVID-19 is unlikely. However, it is possible that the test will give an incorrect (false negative) result in some people with COVID-19. This means that you may have contracted COVID-19 even if the test gave a negative result. In case of symptoms such as headache, migraine, fever, loss of taste and smell, please contact the nearest health care point according to local authority rules. Also, you can repeat the test with a new kit. If suspected, repeat the test after 1-2 days, as the coronavirus cannot be determined at all stages of the infection. Even with a negative result, the rules of spacing and hygiene must continue to be observed.

- INVALID: the control line does not appear. Insufficient sample volume or incorrect procedure are the most likely causes of missing control line. Review the procedure and repeat the test with a new kit or contact your doctor or a COVID-19 diagnosis center.

* NOTE: The intensity of the color in the test line region (T) varies depending on the number of SARS-CoV-2 antigens present in the sample. Therefore the presence of any shade of color in the test region (T) should be interpreted as a positive result.
