COVID 19 Self Test Rapid Antigen Test is a rapid visual immunoassay for the qualitative, presumptive detection of COVID-19 antigens from throat swab, nasopharyngeal swab and nasal swab specimens. The test is intended for use as an aid in the rapid differentia l diagnosis of acute COVID-19 virus infection.
PRINCIPLE
The COVID-19 Antigen Rapid Test Device (Colloidal Gold) detects COVID-19 antigens through visual interpretation of color development on the strip. COVID-19 antibodies are immobilized on the test region of the membrane respectively. During testing, the extracted specimen reacts with anti- COVID-19 antibodies conjugated to colored particles and precoated onto the sample pad of the test. The mixture then migrates through the membrane by capillary action and interacts with reagents on the membrane. If there is sufficient COVID-19 antigens in the specimen, colored band will form at the according test region of the membrane. The presence of a colored band in the test region indicates a positive result for the particular viral antigens, while its absence indicates a negative result. The appearance of a colored band at the control region serves as a procedural control, indicating that the proper volume of specimen has been added and membrane wicking has occurred.

FAQ
Q:What does antigen self test mean?
A:Antigen tests* are rapid tests that usually produce results in 15-30 minutes. Positive results are accurate and reliable. However, in general, antigen tests are less likely to detect the virus than NAAT tests, especially when symptoms are not present. Therefore, a single negative antigen test cannot rule out infection
Q:How do I use a rapid antigen test?
A: Open the rapid antigen test box. and make sure it has not passed its expiry date. Insert the soft end of the stick into one nostril all the way. Move the stick around in the nostril for 15 seconds
Q: What is the difference between a regular COVID test and an antigen test?
A:All COVID-19 tests can only give results that amount to a snapshot in time. That's why it makes sense to wait to take a test either until you have symptoms or until about five days after you've been exposed to someone who has tested positive for COVID-19. Taking a test immediately after exposure doesn't do much good.
Q: How to do covid self test rapid antigen test?
A: gently into 1 of their nostrils until you feel some resistance. inside of their nostril in a circular motion 10 times. If you did not swab the tonsils, swab both nostrils, making 10 complete circles in each nostril. For best performance, test the swab as soon as possible after wiping your nostril.
Q: When should you take a COVID antigen test?
A: If you have symptoms, test immediately, and then test again per the instructions if your first result is negative. If you were exposed to someone who has COVID-19 and you do not have symptoms, wait at least 5 full days after your exposure before testing. If you test too early, you may have an inaccurate result.
