The field of Molecular Diagnostics, or molecular pathology as it is also known, combines the accuracy of molecular biology with laboratory testing methods and applications. RNA or DNA are typically sequenced to look for potential genetic disease signs. Genetic and biomarker testing, which are sometimes used interchangeably, as well as what pharmaceutical companies refer to as companion tests are examples of Molecular Diagnostics test types (a diagnostic protocol used in conjunction with a drug).
The molecular lab can use a wide range of different kinds of equipment. Recombinant DNA tools, Next-generation sequencing (NGS) tools and library building, Polymerase Chain Reaction (PCR) tools including DNA thermal cyclers, and Enzyme-Linked Immuno Sorbent Assay (ELISA) kits are a few examples of these. Although the process of extracting DNA and RNA is typically standardized, the analytical method or procedures that should be used can vary depending on factors including clinical needs and how quickly precise results are required.
