What is molecular diagnostics?

Infectious diseases are caused by a wide variety of organisms, ranging from multi-cellular parasites and fungi to uni-cellular bacteria to non-cellular viruses. These organisms cover a wide range of phyla, and have extremely diverse ways of infecting human beings. In spite of these differences, they all possess nucleic acids (DNA or RNA molecules), their hereditary material. This DNA or RNA forms the basis of their individuality, and because it is the basis of diversity, it is possible to identify these organisms from their DNA or RNA. Unlike other diagnostic methods, which rely on microscopy, culture, biochemical characteristics and indirect antibody detection, molecular diagnostics seeks evidence of a disease at the very basic causative level by detecting the nucleic acids based on PCR (Polymerase Chain Reaction) technology.


This technology is also used to detect changes or mutations in our DNA, which can cause disease conditions known as genetic disorders. While some of these genetic disorders are passed from generation to generation, some happen spontaneously. Genetech offers DNA-based testing services for a wide variety of such genetic disorders and cancer markers.
