1. How does the PCR COVID-19 swab test work? The PCR COVID-19 swab test is the most accurate and reliable test for diagnosing COVID-19. These tests are used to directly screen for the presence of viral RNA, which will be detachable in the body before antibodies form or the symptoms of the disease are present. You can have PCR COVID-19 swab test same-day done at Claret Diagnostics. What is PCR testing? During PCR testing, elements known as reverse transcriptase or DNA polymerase are added to a nasopharyngeal sample in the lab. These elements work to make various copies of any viral RNA that may be present—these numerous copies of RNA help signal a positive result. How does a COVID-19 PCR test works? Sample collection is done using a swab to collect respiratory substance detected in the nose. A swab includes a long soft tip on a long, flexible stick inserted into the nose. After receiving the swab sample, the laboratory expert performs a process called extraction, which isolates genetic material from the sample, including genetic material from any virus that may be present. After the extraction process, experts use special chemicals, and a PCR machine called a thermal cycler. It causes a reaction that creates millions of copies of a small portion of the SARS-CoV-2 virus's genetic material. At Claret Diagnostics, we provide various COVID-19 testings.
