: DNA analysis identifies mutations and chromosomal abnormalities, while RNA analysis focuses on gene expression levels and viral loads.
The field is grounded in the principles of molecular biology, specifically that unique genetic markers correlate with specific diseases or predispositions. Molecular Diagnostics: Fundamentals, Methods, &...

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 Modern laboratories use several key technologies to amplify
: Testing can be performed on various specimens, including blood, tissue, urine, saliva, and cerebrospinal fluid.
