Molecular Biology and Molecular Diagnostics. Molecular diagnostics is a method that is employed to assess biological markers in an individual’s genetic code (in the genome and proteome). This aspect of cellular microbiology focuses on how the cells of individuals express their genes in the form of proteins. Molecular biology is applied in medical testing to monitor and diagnose diseases, identify risks, and decide on the kind of therapies that will achieve the maximum results (Clark, 2010, 170). Molecular biology has contributed in the detection and characterization in the management of disease causing micro-organisms. Consequently, the endeavors have led to a revolutionizing diagnostic microbiology and has formed a critical part of routine specimen processing (Allison, 2009, p 101).

Polymerase Chain Reaction (PCR) methods have facilitated progress in the field through allowing early and rapid detection of micro-organisms which were difficult to detect. PCR has reinforced the work of traditional microbiological techniques which complicated the detection of micro-organisms making it hard or impossible to detect them. Moreover, rapid detection through molecular techniques has been made feasible for pathogen with public health value. Molecular diagnostics have enabled molecular techniques to progress beyond the identification stage. It has gone further to enable the detection of anti-microbial genes with a high resistance level (Clark, 2010, 199). This has enabled the availing of public health information like strain characterization through genotyping.Molecular diagnostics have allowed the treatment of particular micro-organisms through viral resistance detection, as well as viral load testing. This has facilitated the monitoring of responses to anti-viral treatments.the monitoring of viral RNA or DNA has become the standard treatment for various chronic illnesses (Clark, 2010, 178). The measurement of viral load is performed by branched chain DNA signal, competitive PCR systems, or real time PCR. Such advancements have facilitated the management of certain diseases. For instance, HIV viral load testing forms a crucial part of the management of the HIV infection. In this light, this paper has achieved its aim of showing how an aspect of molecular biology is used in the diagnosis or the identification of. Molecular Biology and Molecular Diagnostics.
