Utility of Plasma Circulating Tumor DNA (ctDNA) in Asymptomatic Subjects for the Detection of Neoplastic Disease

Cell-free DNA (cfDNA) is isolated from a blood plasma sample and tested for the presence of 96 specific well-described mutations in 9 cancer driver genes. The presence of more than 2 copies of a mutation may indicate the presence of a malignancy. Follow up with the subject's physician would be needed for an examination and any additional testing that the physician wants to perform to further assess for the development of cancer.
