Rapid antigen tests can also be used to detect bacteria such as Streptococci (rapid strep test). Polymerase chain reaction (PCR) is a common laboratory technique used in research and clinical practices to amplify, or copy, small segments of genetic material. PCR is sometimes called molecular photocopying, and it is incredibly accurate and sensitive. Short sequences called primers are used to selectively amplify a specific DNA sequence. On the other hand, PCR uses different genetic material amplification techniques such as RT-PCR.

We MFG Blue Max band saw tires for all make and model saws. For COVID-19 purposes, it amplifies the sample taken from your nose, throat or saliva to try to find genetic material of the SARS-CoV-2 coronavirus that causes COVID-19.

If someone has become newly symptomatic after having had COVID-19 within the past 30 days,* antigen tests should be used to identify a new infection. Furthermore, there are different types of PCR currently used in the research. Viral tests, including Nucleic Acid Amplification Tests (NAATs, such as Reverse Transcription Polymerase Chain Reaction), antigen tests and other tests(such as breath tests) are used as diagnostic tests to detect current infection with SARS-CoV-2 and to inform an individuals medical care.
