The Evolution of Genetic Testing
A Brief History of Genetic Testing
Genetic testing began as a basic tool to identify chromosomal abnormalities. Over time, it evolved to decode DNA sequences, uncovering critical insights about genetic disorders. Early techniques were slow and costly, but with technological advancements, testing has become faster, more affordable, and widely accessible.
From PCR to Next-Generation Sequencing
The shift from Polymerase Chain Reaction (PCR) to next-generation sequencing (NGS) has been revolutionary.
- PCR: Used for amplifying small DNA segments.
-
NGS: Allows sequencing of entire genomes quickly and accurately.
This transition has enabled researchers to study complex diseases like cancer and rare genetic disorders with unprecedented precision.
How Next-Generation Sequencing is Redefining Genetic Testing
Speed and Accuracy in Testing
NGS can sequence billions of DNA fragments simultaneously, delivering faster results with greater accuracy. This means more reliable insights into genetic predispositions, helping doctors craft personalized treatment plans.
Applications of NGS in Healthcare
