Part II - Analytical phase

Abstract

Next-generation sequencing (NGS) has become a cornerstone of precision oncology, requiring standardized workflows in molecular pathology laboratories. The analytical phase, which includes all procedures from nucleic acid quantification to variant interpreta-tion, plays a central role in ensuring the accuracy and clinical utility of molecular results. This document aims at supporting pathology teams - comprising pathologists, techni-cians, and molecular biologists - during the implementation and execution of the ana-lytical phase of NGS testing. Key topics include clinical indications, platform and gene panel selection, bioinformatics pipelines, quality assurance strategies, and organizational considerations. The goal is to promote standardized, high-quality molecular diagnostics to advance precision pathology.
