【INTENDED USE】
The COVID-19 Antigen Rapid Test (Oral Fluid) is a single-use test kit intended to detect the novel coronavirus SARS-CoV-2 that causes COVID-19 in human oral fluid. This test is designed for home use ¹with self-collected oral fluid samples. The test is intended for use in symptomatic individuals meeting the case definition for COVID-19, and to test asymptomatic individuals limited to contacts of confirmed COVID-19 cases or probable cases and to at-risk health workers. The COVID-19 Antigen Rapid Test (Oral Fluid) obtain preliminary results only, the final confirmation should be based on clinical diagnostic results.
【SUMMARY】
The novel coronaviruses belong to the β genus. COVID-19 is an acute
respiratory infectious disease. People are generally susceptible. Currently,
the patients infected by the novel coronavirus are the main source of
infection; asymptomatic infected people can also be an infectious source.
Based on the current epidemiological investigation, the incubation period is 1
to 14 days, mostly 3 to 7 days. The main manifestations include fever,
fatigue, and dry cough. Nasal congestion, runny nose, sore throat, myalgia,
and diarrhea are found in a few cases.
【PRINCIPLE】
The COVID-19 Antigen Rapid Test (Oral Fluid) is a qualitative membrane-based
immunoassay for the detection of SARS-CoV-2 Antigens in the human oral fluid
specimen.
【REAGENTS】
The test device contains anti-SARS-CoV-2 antibodies.

【TESTING】
Before Testing
Do not place anything in the mouth including food, drink, gum, or tobacco
products for at least 10 minutes prior to collection. Wash your hands with
soap and water for at least 20 seconds before testing. If soap and water are
not available, use hand sanitizer with at least 60% alcohol.
Step 1: Specimen collection
Remove the funnel and plastic tube; fit the funnel onto the tube.
Deeply cough 3-5 times.
Note: Wear a face mask or cover your mouth and nose with a tissue when
you are coughing and keep your distance from other people.
Gently spit oral fluid into the funnel.
The oral fluid (non-bubble) should just reach the height of the scale line.
Note:
If there’s not enough oral fluid collected, repeat the above specimen
collection steps. Place the used funnel into the plastic Biosafety Bag
Step 2: Specimen preparation
Tear to open the buffer and add an entire buffer to the tube with oral fluid.
Fit the tube tip onto the tube. Gently squeeze the tube 10-15 times to mix
well.
Step 3: Testing
Remove the test device from the sealed foil pouch and use it within one hour.
Best results will be obtained if the test is performed immediately after
opening the foil pouch.
Place the test cassette on a flat and level surface. Invert the tube and add 2
drops of solution to the specimen well(S) of the test device and then start
the timer. Do not move the test cassette during test development.
Step 4:
Read the result in 15 minutes. Do not interpret the result after 20 minutes.
After the test is completed, place all the components of the test kit in a
plastic Biosafety Bag and dispose of them according to local regulation. Do
not reuse any used components of the kit. Wash hands thoroughly after test
disposal.
【READ RESULTS】
Please share your test result with your healthcare provider and carefully
follow your local COVID guidelines/requirements.
POSITIVE:* Two colored lines appear*. One colored line should be in the
control region (C) and another colored line should be in the test region (T).
NOTE: The intensity of the color in the test line region (T) will vary
based on the amount of SARS-CoV-2 antigen present in the sample. So any shade
of color in the test region (T) should be considered positive.
A positive result means it is very likely you have COVID-19, but the positive
samples should be confirmed. Immediately go into self-isolation in accordance
with the local guidelines and immediately contact your general
practitioner/doctor or the local health department in accordance with the
instructions of your local authorities. Your test result will be checked by a
PCR confirmation test and you will be explained the next steps.
NEGATIVE: One colored line appears in the control region (C). No apparent
colored line appears in the test line region (T). You are unlikely to have
COVID-19. However, it is possible for this test to give a negative result that
is incorrect (a false negative) in some people with coved-19. This means you
could possibly still have COVID-19 even though the test is negative. In
addition, you can repeat the test with a new test kit. In case of suspicion,
repeat the test after 1-2 days, as the coronavirus cannot be precisely
detected in all phases of infection. Even with a negative test result,
distance and hygiene rules must be observed, migration/traveling, attending
events and etc should follow your local COVID guidelines/requirements.
INVALID: Control line fails to appear.**
Insufficient specimen volume or incorrect procedural are the most likely
reasons for control line failure. Review the procedure and repeat the test
with a new test or contact your doctor or a COVID-19 test center.
【LIMITATIONS】
- Failure to follow the testing steps may give inaccurate results.
- The COVID-19 Antigen Rapid Test (Oral Fluid) is for self-testing in vitro diagnostic use only.
- The results obtained with the test should be considered with other clinical findings from other laboratory tests and evaluations.
- If the test result is negative or non-reactive and clinical symptoms persist, it is because the very early infection virus may not be detected, It is recommended to test again with a new test 1-2 days later or go to the hospital to rule out infection.
- Positive results of COVID-19 may be due to infection with non-SARS-CoV-2 coronavirus strains or other interference factors.

【Q&A】
-
How do I know if the Test worked well?
COVID-19 Antigen Rapid Test is a rapid chromatographic immunoassay for the qualitative detection of SARS-CoV-2 antigens present in human oral fluid. When the control line(C) appears, it means the test unit is performing well. -
How soon can I read my results?
You can read your results after 15 minutes as long as a colored line has appeared next to the Control region(C), do not read the result after 20 minutes. -
When is the best time to run the test?
Test can be done at any time of the day. However, It is recommended to collect
the first oral fluid in the morning. -
Can the result be wrong? Are there any factors that can affect the test result?
The results will only give accurate results as far as the fresh human oral fluid is used and followed the instructions carefully. Nevertheless, the result can be incorrect.
Non-SARS-CoV-2 coronavirus strains or other interference factors may cause a preliminary Positive Result. -
How to read the test if the color and the intensity of the lines are different?
The color and intensity of the lines have no importance for result interpretation. The test should be considered Positive whatever the color intensity of the test line (T) is. -
What do I have to do if the result is positive?
A positive result means the presence of SARS-CoV-2 antigens. A positive result means it is very likely you have COVID-19 and the result should be confirmed. Immediately go into self-isolation in accordance with the local guidelines and immediately contact your general practitioner/doctor or the local health department in accordance with the instructions of your local authorities. Your test result will be checked by a PCR confirmation test and you will be explained the next steps. -
What do I have to do if the result is negative?
A negative result means that you are negative or that the viral load is too low to be recognized by the test. However, it is possible for this test to give a negative result that is incorrect (a false negative) in some people with COVID-19. This means you could possibly still have COVID-19 even though the test is negative.
In addition, you can repeat the test with a new test kit. In case of suspicion, repeat the test after 1-2 days, as the coronavirus cannot be precisely detected in all phases of infection. Distance and hygiene rules must still be observed. Even with a negative test result, distance and hygiene rules must be observed, migration/traveling, attending events and etc should follow your local COVID guidelines/requirements.
