Introduction
Genetic diseases arise from mutations, deletions, duplications, or regulatory disruptions in DNA and often require early, accurate, and precise diagnosis to enable effective treatment and management. Traditional genetic diagnostic methods—such as sequencing, PCR, and cytogenetic analysis—are accurate but frequently time-consuming, costly, and dependent on centralized laboratory infrastructure.
The integration of Artificial Intelligence (AI) with Lab-on-a-Chip (LOC) technology is transforming genetic disease diagnostics by enabling rapid, automated, and highly accurate analysis at the micro-scale. LOC platforms provide miniaturized diagnostic environments, while AI enhances data interpretation, pattern recognition, and decision-making. This topic explores how AI-powered LOC systems are applied to genetic disease diagnostics and their impact on modern healthcare.
