Overview
The bioMerieux EMAG Instrument CDC COVID-19 RT-PCR is part of the CDC COVID-19 RT-PCR protocols that include the following functionality.
Preconfigured CDC COVID-19 RT-PCR protocols that support the preparation of upper and lower respiratory specimens for real-time RT-PCR qualitative detection of nucleic acid from the 2019-nCoV.
Automated calculation of sample and buffer volumes.
Automated calculation or display of reagents at every step in the protocol.
Automatic step transition when required.
Automatic placement of samples when necessary.
Automated assignment of QC Pass/Fail, based on user-selected threshold values.
