Saliva can be more effective for Covid testing: Study By IANS | 0 Views 2-year-old in UP tests positive for new Covid strain. Image Source: IANS News New York, June 12 : The addition of a simple processing step to saliva samples before testing may improve Covid-19 detection rate, eliminate the challenges of nasopharyngeal testing and facilitate mass surveillance, researchers say. The researchers, including Ravindra Kolhe from Augusta University in the US, found that an innovative protocol that processes saliva samples with a bead mill homogeniser before real-time PCR (RT-PCR) testing results in higher sensitivity compared to NPS samples. Saliva as a sample type for Covid-19 testing was a game-changer in our fight against the pandemic. It helped us with increased compliance from the population for testing along with decreased exposure risk to the healthcare workers during the collection process, said lead investigator Kolhe. ....
The collection of nasopharyngeal swab (NPS) samples for COVID-19 diagnostic testing poses challenges including exposure risk to healthcare workers and supply chain constraints. Saliva samples are easier to collect but can be mixed with mucus or blood, and some studies have found they produce less accurate results. ....
According to a new study, the addition of a single step before testing saliva samples using RT-PCR tests can improve their sensitivity and give accurate results, thereby, providing new hope for mass testing and surveillance of the SARS-CoV-2 coronavirus. ....
