SHIELDING™ is a comprehensive genomic profiling for guiding the selection of neoadjuvant/adjuvant therapy, and targeted drugs for subsequent lines of treatment. Used for monitoring the efficacy of neoadjuvant therapy and predicting the risk of recurrence post-surgery before undergoing surgery; for post-surgery MRD detection for predicting risk of recurrence and facilitating adjuvant therapy decision-making. Uses ultra-high sensitivity for ctDNA dynamic monitoring using ATG-Seq™ technology.
