Home Use 15mins Result POCT Covid Swab Rapid Test Kit SARS-CoV-2 Antigen Diagnostic Test
The rapid test kit is used for qualitative determination of novel coronavirus (SARS-CoV-2) antigen in human nasal swab samples in vitro.
1 test/box, 5 tests/box, 25 tests/box for your option!
STORAGE OF ANTIGEN RAPID TEST
• Store at 39 ~ 86 º F (4 ~ 30 º C) in the sealed pouch up to the expiration date.
• Keep away from direct sunlight, moisture and heat.
• DO NOT FREEZE.
HOW TO OPERATE THE ANTIGEN RAPID TEST?
1. Remove a Test Device from the foil pouch by tearing at the notch and place it on a level surface.
2. Holding Extraction Reagent bottle vertically, add BUFFER to the Extraction tube.
3. Insert the nasopharyngeal (and oropharyngeal) swab sample(s) into the extraction solution, then, mix the swab 10 times.
4. Remove the swabs while pressing against the solution tube in order to extract most of the specimen
5. Place the dropper cap and drop 3 drops (60~70μl) into the sample well.
6. Read the result in 10-15 minutes. Do not read results after more than 20 minutes.
What is the difference between an antigen test and a molecular test?
An antigen test detects specific proteins on the surface of the virus. These tests are quicker and less expensive, but have a higher chance of missing an active infection, according to the FDA.
A molecular (PCR or polymerase chain reaction) test detects the virus’s genetic material. These tests require a more complex technology to get results, and it usually takes a day or two to get those results (depending on lab capacity, results may take up to a week).
If an antigen test shows a negative result and you have reason to believe you may have the virus (because of symptoms or exposure), your doctor may order a molecular test to confirm the results.
If antigen tests are less accurate, why would we use them?
Experts say the value in the rapid antigen tests is in the frequency of the testing rather than the accuracy, with repeated testing recommended. According to Science, getting a false negative in an antigen test two or three times in a row is rare. This strategy lines up with the NPR report mentioned above, which would employ daily testing of those in high-risk areas.
