Analytical Validity:
Help
In analytic validation, the WGS assay achieved 99.95% sensitivity, 99.99955% specificity and 99.6% positive predictive value for detecting SNVs. The assay achieved 97.9%, 96.0% and 95.2% sensitivity for detecting Indels of 1-5, 6-15 and 16-50 nucleotides respectively. The assay achieved 96% sensitivity for detecting structural variants in known clinical samples.
