- Accuracy of lung cancer detection measured by sensitivity, specificity, and the AUC of the ROC. [ Time Frame: Approximately 12 months ]
- Accuracy (sensitivity and specificity) in clinical subgroups of interest [ Time Frame: Approximately 12 months ]
- Accuracy of tumor of origin (confusion matrix of predicted versus actual cancer type) [ Time Frame: Approximately 12 months ]
- Adverse events (AEs) associated with the blood specimen collection [ Time Frame: Point in time of blood specimen collection (1day) at enrollment ]
- Expected distribution of the DELFI score in the intended use population [ Time Frame: Approximately 12 months ]
- Analytical performance (e.g. repeatability/reproducibility) [ Time Frame: Approximately 12 months ]
- Accuracy of multi-cancer detection measured by sensitivity, specificity, and the AUC of the ROC and tissue of origin (TOO) accuracy [ Time Frame: Approximately 12 months ]
Biospecimen Retention: Samples With DNA
