​NTU Singapore researchers speed up gold-standard COVID-19 diagnostic test

Clinician-scientists at Nanyang Technological University, Singapore’s (NTU Singapore) Lee Kong Chian School of Medicine (LKCMedicine) have demonstrated a way to improve the speed, handling time and cost of COVID-19 laboratory tests. The improved testing method yields results in 36 minutes – a quarter of the time required by existing gold-standard tests. Their new approach could enable the wider adoption of COVID-19 testing for diagnosis in academic or research laboratories, and allow for screening and research especially in countries and regions with limited laboratory capabilities. The test, which can be done with portable equipment, could also be deployed in the community as a screening tool. Currently, the most sensitive method for testing for COVID-19 is through a laboratory technique called polymerase chain reaction (PCR), in which a machine amplifies viral genetic material by copying it over and over again so any trace of the SARS-CoV-2 virus can be detected. A big bottleneck in sample...
