What Technologies are Used to Lower Detection Limits?
Several advanced technologies are employed to improve detection limits:
1. Liquid Biopsy: This non-invasive method analyzes circulating tumor DNA (ctDNA) in a patient’s blood, offering a promising way to detect cancer early. 2. Next-Generation Sequencing (NGS): NGS allows for the comprehensive analysis of genetic mutations associated with cancer, enhancing early detection. 3. Immunohistochemistry (IHC): IHC uses antibodies to detect specific antigens in tissue samples, helping identify cancer cells at lower concentrations. 4. Molecular Imaging: Techniques such as PET and MRI scans can locate small cancerous lesions that might be missed by other methods.
