Highlights

• Point of care multiplex RT-PCR test for SARS-CoV-2 detection.

• Highly sensitive test with LOD 500 units.

• Self-sample collection to auto results within 45 min.

• Room temperature storage with 24 months self life.

Abstract

We present the point-of-care (POC) molecular diagnostic solution, evaluated during COVID-19 pandemic caused by SARS-CoV-2 (Dec 2021). The POC comprised of a complete platform from self-sampling to RT-PCR testing of SARS-CoV-2 and its variants on portable Compact Q Real time polymerase chain reaction system. The multiplex assay was designed to target S, ORF1, and N genes of SARS-CoV-2 genome in a single tube with RNaseP as endogenous internal control. The present POC enables high accuracy (>95%) and high-throughput testing with a turnaround time of 45 min. It provides a unique platform from self-sample collection to report generation with rapid protocol, pipette and expert-free operation, long shelf-life stability and room temperature storage which enable to increase the efficiency of molecular testing. This novel test named “CoviSwift™ COVID-19 S PLUS RAPID PCR KIT” has been approved by CDSCO, Indian National Regulatory Authority, India, and is in use for clinical settings in India.
