PERFORMANCE EVALUATION
Contrived Clinical Samples
Competitor Comparison
AzureSeq was determined to be compatible with RNA extraction workflow at concentrations at or near LoD. Pooled negative OP swabs were spiked with genomic RNA. Input volume for extraction was 250 μl and elution volume was 80 μl. A 5 μl aliquot of the eluate was added to the PCR reaction.
nCoV2 N1
nCoV2 N2
Detection on nCoV2 N1 and N2 genes: 50 copies of genomic RNA added in a 20 μl reaction. Reaction set-up and RT-qPCR protocol were in accordance with CDC guidance.

Negative nasopharyngeal swabs were spiked with heat-killed SARS-CoV-2 virus at the labeled concentration in copies/uL in starting sample media (saline). Samples were heated at 95C for 5 min, then 5uL of heat-inactivated sample was added to reactions containing 1X AzureSeq CoV-2 reagents. The final reaction volumes were 20ul. Samples were run on a BioRad CFX96 using default ramp rates.
