Now that we're well into the coronavirus epidemic, the actions we must adopt to successfully combat the spread have become evident: a string of conscientious methods like wearing masks, washing hands, and distancing, large-scale testing with fast turnaround times; and contact tracing for people who test positive in order to stop the spread. Combined, these are our best bets while awaiting better treatments and widespread vaccination. Which tests should you employ?Start here: There are tests that diagnose current infection and tests that determine whether you previously had SARS-CoV-2, the virus responsible for COVID-19. The FDA has granted emergency use authorization (EUA) for hundreds of COVID-19 diagnostic tests. The EUA permits the makers to offer tests without official FDA approval since there is a public health emergency. This coronavirus that is novel, COVID-19 is actually a brand new disease. Information about available tests is not complete and choices for testing are constantly changing. Tests differ in regards to precision, cost, tests for people of various years of age, and the ease of using. This blog post provides an overview of the main types of tests. For more details on individual tests, check the FDA's updated list of approved tests, which includes hyperlinks to test manufacturers' websites. Diagnostic tests for current infections If you're looking to determine whether or not you have the virus, there are two types of tests available: molecular tests as well as antigen testing. Molecular tests (also called PCR tests test for viral RNA, test for nucleic acids)
What is the procedure? Nasal swabs, throat Swabs, and tests of saliva or other bodily fluids. Where can you find this test? In a hospital, a medical office, in your car, or even at home. The FDA has authorized בדיקת קורונה that does not require prescription. What's the point of this test? Tests using molecular technology are for genetic material only derived from viruses. How long will it take to see results? It all depends on the lab's capacity. It could take up to 24 hours for the results to be made available, however it is not uncommon for them to take more than a day. Many places report much longer time to finish. How about accuracy? The rate of false negatives a בדיקות קורונה PCR which means you aren't infected even though you do actually have the virus varies depending the length of time that infection has been present in one study, the false-negative rate was 20% when the test was conducted five days after symptoms began, but much more (up to 100%) earlier in infection. False positive rates refer to the number of times the test says you are infected with the virus. This should be very near to zero. False positive results are usually due to contamination of the lab or problems with how the lab performed the test. This is not due to the limitations of the test. A molecular test with a nasal swab is usually the most effective option because it has fewer false negative results than other diagnostic tests , or samples from throat swabs or saliva. Patients in hospital, even, may have other types of samples taken. How much does testing cost? Costs vary widely, ranging from under $10 to hundreds of dollars, depending on the health insurance you have to cover the test or if you'll pay out out of the pocket. It also depends on which test you take and the location it's conducted. It is important to inquire about costs prior to the time, particularly if you are told to go to the ER or a private testing facility. Some communities offer free tests. To learn more you can go to the site or contact your local government. The final line If we could have quick, extremely accurate, and cheap tests at home We could check ourselves prior to going to work, heading off to school, or otherwise having a conversation with others. We could more rely on the testing to determine when it is safe to remove ourselves, wear a mask or take other measures. But we're not there yet.
