Molecular diagnostics is growing quickly. Molecular diagnostics tests perceive whether certain DNA or RNA sequence is linked with the disease including the single nucleotide polymorphism (SNP). The extension in diagnostics and personalized therapy is being driven by chances in molecular diagnostics. Molecular diagnostic tests whether DNA or RNA sequences are associated with the disease, along with single nucleotide polymorphism (SNP), deletions, rearrangements, insertions and others. Multiparametric Molecular Diagnosis also has wide applications. Dynamic contrast enhanced magnetic resonance imaging of the breast has been the main stay of breast MRI with an excellent sensitivity but limited specificity. Current data suggests that using other functional MRI parameters such as diffusion waited imaging and proton MR spectroscopic imaging may furnish additional specificity. Various technologies have become commercially accessible for the multiparametric molecular detection of RTIs in the past decade including tests based on PCR-array, PCR-mass spectrometry, and multiplex qPCR technologies. Molecular Forensics gives an inclusive coverage of the widely important role that molecular analysis plays with in forensic science. Genotyping with DNA probes can recognize every person on earth. Naturally occurring variations in the nucleotide sequence of DNA results in genetic differences between people. Applying scientific principles to investigate and initiate facts of interest in relation to criminal, civil, and administrative hearings. Molecular pathology is based on the revelation of new techniques that hugely increase the diagnostic accuracy when facing with challenging differential diagnoses. Carcinoma of the prostate is the second leading cause of male cancer-related death in the United States. Preferable indicators of prostate cancer and progression are required to avoid needless treatment, anticipate disease course, and develop more effective therapy.
