Rapid detection of SARS-CoV-2 by pulse-controlled amplification (PCA)

In the current pandemic of SARS-CoV-2, rapid identification of infected individuals is crucial for management and control of the outbreak. However, transport of samples, sample processing and RT-qPCR analysis in laboratories are time-consuming. Here we present a prototype of a novel nucleic acid-based test format - pulse controlled amplification - that allows detection of SARS-CoV-2 directly from up to eight swab samples simultaneously without the need for RNA extraction within 25 min with a sensitivity of 100 % for samples with a viral load of ≥ 1.6 × 10e3 copies/μl This new principle might pave the way to rapid and sensitive point of care testing.
