Molecular Assays

Real Time qPCR
Isolation: MagNA Pure 96 (Roche)
RT-PCR: ABI 7500 PCR machines (Thermo Fisher)
Results & QC

 

    • Viral load reported in log10 copies (cp)/ml
    • Quantification based on four-point control SARS-CoV-2 virus with known concentration
    • QC based upon trending of four-point control and internal control
