Diagnostic Techniques in Hematological Malignancies

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 [9]. Studies have demonstrated the importance of advanced blood culture techniques for identification and antimicrobial susceptibility testing along with molecular methods like target amplification by different PCR's, gene sequencing, pyrosequencing, reverse hybridization, mass spectrometr

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.

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

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 [1], 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. The short interval required to perform molecular diagnostic tests and analyze their results is an additional positive aspect of this type of testing, resulting in more efficient patient management, especially in cases of.

Molecular Diagnostic Techniques : A Brief Review

Molecular diagnostic tests with application to clinical diagnostics involve studies in infectious diseases, inherited diseases, oncology, predisposition to disease, or the description of polymorphisms linked to disease states. General considerations in the design of evaluation of diagnostic test trials and statistical principles for reporting the results are discussed Molecular diagnostic techniques have been successfully used in the investigation and control of classical and emerging nosocomial pathogens, such as the enterobacteriaceae, Pseudomonas aeruginosa, Staphylococcus aureus, coagulase-negative staphylococci, enterococci, Candida albicans, M. tuberculosis, and Chlamydia pneumoniae [79, 192-194]


Introduction. In recent years, advanced molecular techniques in diagnostic microbiology have been revolutionizing the practice of clinical microbiology in the hospital setting. Molecular diagnostic testing in general and nucleic acid-based amplification methods in particular have been heralded as diagnostic tools for the new millennium Purpose Patients with Fanconi anaemia (FA), a rare DNA repair genetic disease, exhibit chromosome fragility, bone marrow failure, malformations and cancer susceptibility. FA molecular diagnosis is challenging since FA is caused by point mutations and large deletions in 22 genes following three heritability patterns. To optimise FA patients' characterisation, we developed a simplified but.
