molecular diagnostics is creating new careers for researchers in many ﬁ elds. It was suggested that the fastest-growing, most profitable area in laboratory medicine at the moment is molecular diagnostics. Clearly, much of this improvement has come as a result of new knowledge of the human genome and related proteins, which form the foundation. The tools of molecular biology have proven readily adaptable for use in the clinical diagnostic laboratory and promise to be extremely useful in diagnosis, therapy, and epidemiologic investigations and infection control (1,2). Although technical issues such as ease of performance, reproducibility, sensitivity, and specificity of molecular test Molecular techniques in clinical microbiology Molecular biology is the science of biomolecules. Even though the term biomolecules includes all molecules such as proteins, fatty acids etc, it is refers to nucleic acid these days. The application of molecular technology in medicine is almost endless, some of the applications o rapid and molecular diagnostic techniquesFrom .

For a MD approach to succeed in a clinical setting, it is critical that CLS, residents, and clinicians be well trained in performing, troubleshooting, and interpreting the assays genetics. The proliferation of assay methods, the number of targets for molecular diagnostics and the absence of standard reference materials contribute to variability in test results among laboratories. This article provides a comprehensive overview of reference materials, related documentary standards and proficiency testing programs

Molecular diagnostics for examining the expression pattern of cancer cells offer great promise for revolutionizing our approaches to screening, diagnosis, and classification for many different types of cancer. All these techniques have led to the discovery of various therapeutic molecules for cancer treatment, and the optimization of drug therapy [3,4]. Emerging molecular-cytogenetic techniques, such as fluorescence in situ hybridization (FISH), and other molecular technologies have overcome many of the drawbacks of conventional diagnostic methods. In this review paper, the utility and application of common molecular diagnostics in clinical hematology are discussed The molecular diagnostic techniques used for the detection and characterization of microorganisms may be separated into several broad categories. These are direct hybridization, nucleic acid amplification, and a variety of methods for postamplification analysis molecular diagnostic techniques is very important. The reason for this is that some collection devices are coated with a substance that can result in inhibition of the molecular assay. For example, some coagulates such as heparin result in inhibition of the molecular assay an

The molecular diagnostics is a collective term for techniques used to analyse biological markers involved in a wide range of human ailments Nucleic acid-based diagnostics detect the presence of a pathogen either by directly detecting the presence of DNA or RNA nucleic acids in the host or by first amplifying the pathogen DNA or RNA. Nucleic acid-based diagnostics are a standard central laboratory technique, although simplified nucleic acid-based diagnostics that may be useful in resource-poor settings are emerging The pharmaceutical industry is still struggling to cure cancer despite pouring enormous resources into the search for new treatments. We take a look at the some of the current technologies for the discovery and delivery of molecular diagnostic, prognostic and predictive tests and speculate on where this area is heading with regard to advanced technologies and likely future requirements
This is due to sensitive and robust techniques like real time PCR and high throughput techniques like microarray. Among the various molecular techniques discussed above, the use of the PCR in molecular diagnostics is considered the gold standard for detecting nucleic acids and it has become an essential tool in the research laboratory Diagnostic microbiology has traditionally relied on the cultivation of an infecting agent in an in vitro system. However, the limitations of these methods have led to the development of alternative, molecular techniques which can detect specific microbial proteins or nucleic acids directly in body fluids Molecular diagnostic techniques for viral testing have experimented a rapid development during the last years , and have been introduced in the majority of laboratories as a new way for the diagnosis of human pathogens like viruses. This field of molecular microbiology presents man Molecular techniques also enable clinicians to monitor disease progression during treatment and to make accurate prognoses.
