For more information, see our Isolation page. If you are experiencing symptoms, stay home, and keep your distance from others. If you do not have symptoms and have not been advised by a medical professional to quarantine at home, you may resume your normal activities. While waiting for your test results, continue to practice physical distancing, wear a face covering when near other people who are not in your household, and wash your hands often. If ending isolation before day 10, it is strongly recommended you wear a mask until after day 10 UNLESS you get two sequential negative antigen tests one day or more apart.IF you are fever-free for 24 hours (without fever-reducing medicines) AND have no or improving symptoms you can end your isolation period. If you have COVID-19, an antigen test is no longer recommended for ending isolation after day five.Once the form is submitted, you will receive links to isolation and quarantine guidelines and available resources. Please fill in this form to self-report your at-home test result.If possible, you can also contact your health care provider for guidance. If you test positive with an antigen test, isolate as described on our Isolation page.Average turnaround time is quite fast, ranging 15 minutes to one hour, depending on the test and/or tester. Antigen tests are also known as rapid tests or at-home tests. With antigen tests, positive results are usually accurate, though negative tests may need to be confirmed. You can contact NPR science correspondent Richard Harris at. Should I get testedRegardless of your vaccination status, if youve been around someone who has COVID-19, you should get tested at least 5 days after your. But unless these tests are proven to be highly accurate, physicians would still need to follow up a positive result with a PCR test to make a medical diagnosis. As a result, they could be used to screen people in hospitals, certain workplaces, or in other instances where it's important to find out quickly whether someone is currently at risk of spreading the disease. How quick is it: These tests should provide results in just a few minutes. Jordan Laser, a lab director at Northwell Health, notes antigen testing is used for rapid strep tests, which are reliable, and rapid flu tests, which are not. Researchers do not expect it to be as accurate as the PCR diagnostic test, but it is possible the antigen tests could be used to screen patients for infection. The company, Quidel Corp., says it will use the first 40,000 tests to get a better idea about the accuracy of its test. How accurate is it: The first of these tests gained FDA clearance on May 8. This is the same technology used in your doctor's office for rapid strep testing. It does this by looking for proteins from the virus (as opposed to the diagnostic test, which looks for genetic material). How it works: Antigen tests can identify virus in nose and throat secretions. Initially it will not be used to diagnose disease, but it may be used to screen people to identify those who need a more definitive test. It may be used as a quick test to detect active infections. What it does: This test identifies people who are currently infected with the coronavirus. Some research labs use a more sophisticated antibody test, called an Elisa (Enzyme-linked immunoassay) that are more accurate but are not as widely available. If you have any symptoms of COVID, test immediately.A positive test is a reliable result no matter how early you take the test or the type of test. COVID symptoms can start anywhere from 2 to 10 days after infection with the virus. How quick is it: These tests generally produce results in a few minutes, based on a drop of blood taken from the finger. COVID tests are pretty accurate once you have symptoms. Still, these tests can provide good information about rates of infection in a community, where errors in an individual result have less impact. And researchers say, even if you were certain you had antibodies to the coronavirus, it's still unknown if that protects you from getting sick again. In general, these tests aren't reliable enough for individuals to act based on the results. Other tests are being validated by individual medical labs or university researchers. A few tests have voluntarily submitted to extra FDA approval. The Food and Drug Administration has allowed them to be marketed without FDA authorization, and quality is a great concern. How accurate is it: There are more than 120 antibody tests on the market. These antibodies generally arise after four days to more than a week after infection, so they are not used to diagnose current disease. Your body produces antibodies in response to an infectious agent such as a virus. It looks for antibodies to the coronavirus.
