<unk>  is an emerging discipline within<unk>  which is focused in the study and diagnosis of disease through the examination of molecules within organs, tissues or bodily fluids.<unk>  shares some aspects of practice with both anatomic<unk>  and clinical<unk> ,<unk>  biology, biochemistry, proteomics and genetics, and is sometimes considered a "crossover" discipline. It is multi-disciplinary in nature and focuses mainly on the sub-microscopic aspects of disease. A key consideration is that more accurate diagnosis is possible when the diagnosis is based on both the morphologic changes in tissues (traditional anatomic<unk>  and on<unk>  testing. It is a scientific discipline that encompasses the development of<unk>  and genetic approaches to the diagnosis and classification of human diseases, the design and validation of predictive biomarkers for treatment response and disease progression, the susceptibility of individuals of different genetic constitution to develop disorders.<unk>  is commonly used in diagnosis of cancer and infectious diseases. Techniques are numerous but include quantitative polymerase chain reaction (qPCR), multiplex PCR, DNA microarray, in situ hybridization, in situ RNA sequencing, DNA sequencing, antibody based immunofluorescence tissue assays,<unk>  profiling of pathogens, and analysis of bacterial genes for antimicrobial resistance. Integration of<unk> " and "epidemiology" led to an interdisciplinary field, termed<unk> <unk> cal epidemiology" (MPE), which represents integrative<unk>  biologic and population health science.
