Scientists from the Federal University of São Carlos (UFSCar), supported through the Research Support Foundation of the States of São Paulo (FAPESP), have developed two new strategies to identify instances of COVID-19 that can increase mass in Brazil.
Both tests detect the virus through saliva and are very sensitive, as is the reference RT-PCR, and charge at least one-third of the value of an RT-PCR test, which lately has a value of between $60 and $90.
According to the coordinator of studies, Ronaldo Censi Faria, the first check developed through his team uses a device with the same operating precept as a glucometer. The result comes out fast, is reliable and can be sent to a cell phone. between 30 and 60 minutes, but the reliability is the same as that of RT-PCR, so it is different from [the reliability] of the immediate verifications, and has a very low cost,” the researcher said.
Ronaldo Censi went on to say that this can trip up against other diseases, or situations such as Alzheimer’s disease, leishmaniasis, cancer and leprosy.
In another control developed through their team, scientists use a platform already widely known to laboratories, known as Elisa, which reads enzymes and can analyze 96 saliva samples every 30 minutes. an hour. Every 30 minutes you can analyze 96 samples, so you can perform thousands of checks in a day,” Censi said.
According to the researchers, by using a generation already known to laboratories, this type of control can be temporarily followed through interested corporations and assume two bottlenecks in the country’s massive control campaign: price control and diagnostic time.
