COVID Rapid Antigen Test, 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.
ABOUT MUTATED VIRUSES
Currently, these variants mainly affect the RBD fragment of the S protein, regardless of whether it is N501Y in the UK, 501Y.V2 in South Africa or B.1.617 in India. The constant fragment (N protein) used as the target fragment in the COVID-19 rapid antigen detector was not mutated.
PROCEDURE
Specimen treatment:
1. After the sampling, place the swab specimen into the tube.
2. Roll the swab at least 20 times while pressing the swab against the bottom and side of the extraction tube.
3. Roll the swab head against the inside of the Extraction Tube as you remove it. Try to release as much liquid as possible. Dispose of the used swab in accordance with your biohazard waste disposal protocol.
4. Put on the tube tip.
5. Add 3 drops of extracted sample into the sample well. Do not handle or move the Test Device until the test is complete and ready for reading.
6. As the test begins to work, color will migrate across the membrane. Wait for the colored band(s) to appear. The result should be read at 10 minutes. Do not interpret the result after 20 minutes.
FAQ
Q:
What does a rapid antigen test test for?
A: "Unlike the PCR test, the antigen test can only determine if you have an active virus in your body. The rapid test can't detect small amounts of the virus or asymptomatic cases as accurately as the PCR test can," Heather said
Q:What is the difference between a regular COVID test and an antigen test?
A: PCR tests are accurate but can take a long time to produce results. Antigen tests, the other major type of coronavirus test, while much faster, are less accurate. Antigens are substances that cause the body to produce an immune response – they trigger the generation of antibodies.
Q: When to use a COVID 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.
