Molecular Diagnostics: Why its important tool in biotechnology?

Molecular diagnostic technologies offer the potential for moving from diagnostics to prognostics. It includes all tests and methods to identify a disease or the predisposition for a disease analyzing Dna- or RNA of an organism. Genomic discovery will fuel the diagnostic marketplace because every gene-based therapeutic might need an accompanying (molecular) diagnostic test.

Non-invasive or minimal-invasive procedures to obtain the material for tests will facilitate the implementation. Cross-benefits like almost instant diagnostic results, more targeted therapies and shorter hospitalization times constitute higher costs for molecular test in comparison to traditional analyses like microbiology today. But molecular diagnostics will help to abate cost for diagnosis, therapy and healthcare altogether in the middle-term.

These novel tests utilize sophisticated analytical techniques such as microarrays and mass spectrometry. Molecular diagnostics are particularly applicable to the early detection of cancer.., Affymetrix and Illumina have both created array-based products that enable high-speed analysis of DNA, RNA, and proteins as tools for disease research, drug development, and molecular tests. These gene-sequencing tools are being applied at an earlier stage.
