As SARS-C0V-2 variants emerged, researchers developed a PCR test that uses molecular beacons not only to diagnose COVID-19 infection, but also to identify the specific variant causing that infection.

New COVID-19 restrictions for international travel and other activities are fueling consumer demand for highly accurate polymerase chain reaction, or PCR, tests with rapid turnaround times. Some ...

Since the start of the COVID-19 pandemic in the United States, over 46 million positive coronavirus test results have been reported to the U.S. Centers for Disease Control and Prevention (CDC). When ...

The PerkinElmer New Coronavirus Nucleic Acid Detection Kit. PerkinElmer’s COVID-19 test kit has received a reissued Emergency Use Authorization (EUA) from the FDA enabling its use through sample ...

COVID-19 is commonly diagnosed by quantitative fluorescence real-time reverse transcriptase-polymerase chain reaction (qRT-PCR) (1, 2). The test is the sequential action of two enzymes–an ...

At-home PCR tests are just as accurate as those done in a lab. At-home antigen tests are more budget-friendly and give results quicker, but there is a greater chance of a false negative. As of ...
