The best COVID-19 test depends on the individual circumstances, including the availability of testing in your area, the urgency of your need for results, and your healthcare provider's recommendations.
Here are a few types of COVID-19 tests that are currently available:
PCR (polymerase chain reaction) tests: These tests are considered the most accurate for detecting current COVID-19 infection. They work by detecting the genetic material of the SARS-CoV-2 virus in a sample from the nose or throat. Results can take several days, depending on the laboratory processing the test.
Rapid antigen tests: These tests are less sensitive than PCR tests but can provide results within 15-30 minutes. They detect specific proteins from the SARS-CoV-2 virus in a nasal or throat swab.
Antibody tests: These tests detect antibodies produced by the body in response to a COVID-19 infection. They are not used to diagnose active infections but can be useful in determining if someone has previously been infected with the virus.
