How does gene expression diagnostics work, and what do the results actually tell us?
Gene expression-based diagnostics open up new possibilities for characterizing biological processes at the molecular level and applying them diagnostically. But how do such tests actually differ from traditional molecular target detection assays? And how can the resulting findings be interpreted correctly?
Our new white paper, “Interpreting Gene-Expression Diagnostics: From Molecular Signatures to Clinical Classification”, provides a clear overview of the fundamentals of gene expression diagnostics and explains how the combined expression of multiple genes yields a diagnostic result.
Key topics include:
- The difference between gene expression diagnostics and traditional target detection
- The importance of reference genes and molecular signatures
- How classifiers translate gene expression patterns into diagnostic classes
- why classifier outputs can be continuous and how decision thresholds are used
- What “equivocal” or “undetermined” results mean and why they can represent an important, scientifically grounded category of results.
Using PsorX-LabDisk and Erysk-TargetDisk as examples, the white paper illustrates different types of classifier outputs.
The white paper is intended for customers, partners, dermatologists, dermatopathologists, and anyone who would like to better understand how gene expression diagnostics work and how molecular results should be interpreted in a diagnostic context.
This is because molecular diagnostics do not simply yield a “positive” or “negative” result: they can map complex biological expression patterns and thus serve as an objective source of molecular information that complements clinical and histopathological assessments.
