Status of SARS-CoV-2 detection systems (RT-PCR)
enabled by data from GISAID logo

This service aims to verify the systems for the diagnostic detection of 2019-nCoV by real-time RT-PCR amplification.
All oligonucleotides (primers and probes) used for each system are aligned against all the sequences from the GISAID EpiCoV™ database and the alignment identity scores are checked. A color code is finally delivered to the system in base of its ability to amplify or not the corresponding SARS-CoV-2 isolate. The details are available on the results pages.
At the moment the 3 systems published by the Centers for Disease Control and Prevention (2019-nCoV_N1, 2019-nCoV_N2 and 2019-nCoV_N3) and the 2 systems published by the Charité Hospital (Berlin, Germany - RdRP and Sarbeco) are monitored.
