High-Risk Populations

This study evaluates the feasibility and cost-effectiveness of using a blood-based liquid biopsy assay as a pre-screening tool before low-dose CT (LDCT) for lung cancer screening. By identifying individuals unlikely to have lung cancer, this approach aims to reduce unnecessary LDCT scans, radiation exposure, and healthcare costs, while improving early detection, particularly among high-risk individuals including never-smokers with a family history of lung cancer.
