![]() How is the test done?Īn antigen test works by looking for specific viral markers called antigens. It’s possible that you’ll also see this type of test referred to as a COVID-19 rapid test. Similar to the molecular test, the antigen test can be used to determine if you currently have COVID-19. The actual cost for a molecular test is estimated to be between $75 to $100. The Families First Coronavirus Response Act (FFCRA) currently ensures access to free testing for COVID-19, regardless of insurance status. ![]() Because of this, getting tested late can also potentially give a false-negative result.īecause of these factors, it’s vital to seek testing as soon as you begin experiencing COVID-19 symptoms. Testing too late: Viral genetic material in the upper respiratory tract begins to decline after the first week of illness.Testing too early: It can take up to 5 days after exposure before the virus’s genetic material can be detected, so you may receive a false-negative result if you get tested within this window.Aside from errors in sample collection, transport, or processing, timing can play an important role. It’s possible that you could receive a false-negative result on a molecular test. The test typically doesn’t need to be repeated after you receive your result. For example, a 2021 Cochrane review found that molecular tests diagnosed 95.1 percent of instances of COVID-19 correctly.īecause of this, a positive result on a molecular test is often enough to diagnose COVID-19, particularly if you also have COVID-19 symptoms. The molecular test is considered to be the “gold standard” for diagnosing COVID-19. When samples need to be sent to a lab, it may take 1 to 3 days to receive a result. For example, results can be received in 15 to 45 minutes using some point-of care tests. Turnaround time can vary for molecular tests. You can receive a molecular test at many locations, including, but not limited to: Additionally, some types of molecular tests can be performed on a saliva sample that’s collected by asking you to spit into a tube. Most molecular tests collect a sample using a nasal or throat swab. To improve accuracy, many molecular tests can detect multiple viral genes instead of just one. Molecular tests use specific probes to detect the presence of the genetic material of the novel coronavirus. reverse transcription loop-mediated isothermal amplification (RT-LAMP) test.reverse transcription polymerase chain reaction (RT-PCR) test.You may also see this type of test referred to as a: The molecular test for COVID-19 is used to help diagnose a current infection with the novel coronavirus.
