Sample QC
DRAGEN TruSight Oncology 500 uses QC metrics to assess the validity of analysis for DNA libraries that pass contamination quality control. If the library fails one or more quality metrics, then the corresponding variant type or biomarker is not reported, and the associated QC category in the report header displays FAIL.
DNA library QC results are available in the MetricsOutput.tsv
file. Refer to Metrics Output for details.
CONTAMINATION_SCORE
The contamination score is based on VAF distribution of SNPs.
