Which Is The Best Covid-19 Test?

COVID-19


Now that we're well into the COVID-19 pandemic, steps we need to adopt to successfully combat the spread have become evident: a string of conscientious precautions like wearing masks washing your hands and distancing; widespread testing with quick turnaround times; and contact tracing for those who are positive, to slow the spread. In combination, these are the best choices as we await better treatments and the widespread introduction of vaccination.


Which tests should you choose to use?


Start here Start here: There are tests to identify current infections and tests that determine whether you previously had SARS-CoV-2, the virus that causes COVID-19.


FDA has issued an emergency use authorization (EUA) for hundreds of COVID-19 diagnostic test. Because of an emergency in the public domain it allows companies to market their tests without formal FDA approval.


This novel coronavirus, COVID-19 is actually a brand new disease. Information about available tests is not comprehensive and the choices for testing are constantly changing. Tests vary in precision, cost, tests for people of various ages, and convenience. This blog post provides the key features of the most popular types of tests. You can find more information about individual tests on the FDA's updated list. It also includes links to the websites of test manufacturers.


Current infection diagnostic tests


If you want to know whether or not you're suffering from the virus There are two kinds of tests available: molecular tests and antigen tests.


Molecular tests (also called PCR tests or tests for viral RNA, and nucleic acid test)




How is it done?


Testing of saliva and other bodily fluids including throat swabs, nasal swabs, and swabs.


Where can you take this test?


In a hospital, the office of a doctor or even in your car or at your home. The FDA has approved for use in the following locations, and doesn't need the prescription of a doctor.


What's the point of this test? The tests for molecular genetic material only derived from viruses.


What is the typical time to get the results?


Everything depends on the laboratory's capabilities. Results may be ready in a matter of hours, but they usually will take at least a week or two days. A lot of places have reported much longer turnaround times.


What is the accuracy of your data?


The percentage of false positives (a PCR (which say you don't have a virus) varies depending upon the length of time that the virus has been present. One study found that false negative rates were at 20% for five days after the first symptoms began, but higher rates (up to 100%) when testing was conducted earlier in the infection.


False positive rates are the percentage of the test says you are infected with the virus. This should be close to zero. False positives are generally due to laboratory contamination, or issues with the method the lab performed the test. It is not because of limitations in the test.


A molecular test using the nasal swab is typically the best option, because it is less likely to give false negative results than other diagnostic tests , or samples of throat swabs, or saliva. People who are in the hospital, though they may be able to have different types of samples taken.


How much does testing cost?


Cost varies widely, from less than $10 to hundreds of dollars, based on the health insurance you have to cover the test, or if you'll have to pay out out of pocket. It also depends on which test you get and where the test is conducted.


It's essential to inquire about cost ahead of time, particularly if you have been told to visit the ER or a private testing facility. Certain communities provide free tests. For more information, you can visit the website or contact the local office of your government.


The final line


We could easily, precisely, and cheaply conduct tests at home before we went to school or to work. If tests were more precise, we could more confidently rely on tests to determine when it's safe to relax distancing, masking and other precautions. We aren't there yet.
