Deep data QC
67/100 · DStandardized, field-standard QC computed by touching the data — every metric states how it was obtained · evidence: measured
This NextSeq 550 amplicon sequencing run for SARS-CoV-2 yielded 574,000 short reads with moderate quality (96.5% Q20, 94.3% Q30) and lower overall sequencing depth (167.6 million bases) than higher-throughput instruments. The clean amplification (0.005% N-content) is reliable, but assess whether total bases support adequate per-amplicon coverage in your multiplexed design. Best suited for rapid surveillance applications where full-depth sequencing is not required.
The D grade is a transparent weighted average. Each metric below scored from 0–100% against the published amplicon thresholds, weighted by its importance; nothing is hidden or subjective.
