We are at the beginning of the COVID-19 epidemic. The steps that must be taken to stop the spreading have been laid out clearly. These include conscientious preventive measures like wearing masks, distancing, and washing your hands, as well as quick testing; and a contact trace for those who are positive. In combination, these are the best choices as we await more effective treatments and mass vaccination. Which tests should you choose to use?Start here Here are some tests that detect current infection, as well as tests that show whether you have previously been diagnosed with SARS-CoV-2 the virus responsible for COVID-19. The FDA has granted an emergency use authorization (EUA) for hundreds of COVID-19 diagnostic tests. Since there is an emergency in the public domain it allows companies to sell their tests without the formal FDA approval. Because this novel coronavirus is indeed novel, and COVID-19 is a brand new disease, the information on the available tests isn't complete, and testing options keep changing. Tests vary in terms of accuracy, cost, recommended usage for individuals of different age groups, and ease of use. This blog post outlines the major features of various kinds of tests. Find more details regarding individual tests on FDA's updated list. The post also contains links to the websites of the manufacturers of tests. Diagnostic tests for current infections There are two kinds of testing that can be utilized to find out whether you are infected: antigen and molecular tests. Tests for molecularity (also called PCR tests, tests for viral RNA, and nucleic acids test)
What is the procedure? Swabs of the throat, nasal swabs, and tests of saliva and other bodily fluids. This test can be taken at any location. In a hospital, the medical office, in your car, or even at your home. The FDA has granted בדיקות קורונה PCR which does not require a prescription. What do the tests look for? Molecular tests are for genetic material that comes from viruses. What is the typical amount of time required to see the results? Everything depends on the lab's capacity. It could take up to 24 hours for the results to be released, but it's not unusual to see them take longer than one day. Longer turnaround times are reported in many places. How accurate is your information? The rate of false negatives a מעבדות קורונה which indicates that you don't have the virus when you actually do have the virus is dependent on how long the infection has been present for: in one study, the false-negative rate was 20% when the test was carried out five days following the time symptoms started, but was much higher (up to 100%) early in infection. False positive rates are the amount of times that the test claims you have the virus. This should be close to zero. Most false-positive results are thought to be caused by lab contamination or other problems in the way the lab conducted the test, and not to the test's limitations the test itself. A molecular test using the nasal swab is typically the best choice, as it is less likely to give false negatives than other diagnostic tests , or samples taken from throat swabs or saliva. Patients admitted to the hospital, however they may be able to have different types of samples taken. How much does testing cost? The price of the test may vary from as little as 10 dollars to hundreds of dollars, depending on whether you have insurance that covers it , or the cost will be paid out of pocket. Also, it depends on the test you get and where the test is conducted. It is important to inquire about the cost prior to time, particularly if you are told to go to the ER or a private testing center. Some communities offer free tests. To learn more, you can visit the website or call the local office of your government. The bottom line If we had fast, highly accurate, and inexpensive tests at home We could check ourselves prior to going to work, going to school, or having a conversation with others. We could rely more on the tests to know when it is safe to remove ourselves, wear a mask or take other measures. However, we're not there yet.
