COVID-19 Testing

In March of 2020, the U.S. declared a state of emergency due to the rising number of positive COVID-19 cases. There was an immediate need for more privately owned laboratories to assist the federal government in the fight against the virus. Fortunately, we already had the instruments and supplies needed to run the polymerase chain reaction (PCR) test, which is the most accurate test for the diagnosis of COVID-19. This allowed us to jump start our coronavirus testing program, and offer much needed testing to both local and national organizations. Through continued research and development, we now conduct a variety of COVID testing, including both individual swab testing, specimen pooling, and a POD testing program.

Want to learn more about how COVID-19 testing is performed at PathAI Diagnostics? Check out our behind-the-scenes look at the entire process: from collecting a nasal swab, to processing on our Roche Cobas 6800 platform. You’ll also meet some inspiring young people that have chosen to pursue science and play an integral part in the lab.
