Modern laboratories use several key technologies to amplify and analyze genetic material: Molecular diagnostic techniques - PMC - NIH By focusing on genetic and molecular levels, it

Molecular diagnostics (MDx) is a transformative field of medicine that analyzes biological markers—primarily DNA, RNA, and proteins—to diagnose diseases, assess risk, and guide personalized treatment. By focusing on genetic and molecular levels, it offers significantly higher sensitivity and specificity than traditional culture-based or macroscopic methods. Core Fundamentals and proteins—to diagnose diseases

: The primary goals are sensitivity (detecting even minute quantities of genetic material) and specificity (accurately identifying the exact pathogen or mutation). Primary Diagnostic Methods
