The testing device first heats the saliva to 203 degrees Fahrenheit, the temperature at which viral particle shells break apart and release their genetic material. The platform uses reverse transcription loop-mediated isothermal amplification, or RT-LAMP, to detect the virus. Within 45 minutes, test results are sent to a custom android app developed by the researchers. Guan and his team developed a palm-sized testing kit, where an individual spits into a cartridge and inserts it into processing platform. “We wanted to create a viable alternative to the PCR for people to use at home, without having to endure the invasive nasal test.” “PCR test results take about an hour to develop in a lab, but you have to factor in the time it takes to send the sample to a lab and for the lab to process it,” said principal investigator Weihua Guan, associate professor of electrical engineering and of biomedical engineering in Penn State’s College of Engineering. In preliminary tests, the platform detected the COVID-causing virus with the same level of sensitivity as PCR tests. ![]() To bridge the gap between accuracy and convenience, Penn State researchers have developed an at-home, saliva-based testing platform that can provide results in 45 minutes. ![]() Rapid antigen-detecting tests, on the other hand, are convenient, but less reliable than PCR tests. ![]() However, they can take a few days to process, resulting in unnecessary quarantine for negative individuals or delays for those who require proof of negative testing for travel or other commitments. PCR tests, also called molecular tests or nucleic acid tests, are considered the gold standard in detecting the presence of SARS-CoV-2, the virus that gives rise to COVID-19. ![]()
