Overview
The primary purpose of DNA extraction from plasma or serum is to obtain purified DNA for molecular testing. This includes identifying genetic mutations associated with hereditary disorders, detecting oncogenic mutations in cancer patients (liquid biopsy), monitoring minimal residual disease, and diagnosing infectious diseases by detecting pathogen DNA. The extracted DNA can be used for various applications such as next-generation sequencing, real-time PCR, and microarray analysis. Early detection and precise diagnosis facilitated by this test can guide treatment decisions and improve patient outcomes.
