Molecular/Genomic Reference Materials (RMs) are selected or engineered to model a specific genetic biomarker as it occurs in a patient biopsy. Reference materials (RM) are used for a calibration of the measuring system, for assessment of a measurement procedure, for assigning values to materials, or for quality control .
Quality control (QC) is a measure of precision, or how well the measurement system reproduces the same result over time and under varying operating conditions. Laboratory quality control material is usually run at the beginning of each shift, after an instrument is serviced, when reagent lots are changed, after equipment calibration, and ...
Molecular diagnostics is a collection of techniques used to analyze biological markers in the genome and proteome, and how their cells express their genes as proteins, applying molecular biology to medical testing.
An assay (analysis) is never an isolated process, as it must be accompanied with pre- and post-analytic procedures. Both the communication order (the request to perform an assay plus related information) and the handling of the specimen itself (the collecting, documenting, transporting, and processing done before beginning the assay) are pre-analytic steps.
Clinical quality management systems (CQMS) are systems used in the life sciences sector (primarily in the pharmaceutical, biologics and medical device industries) designed to manage quality management best practices throughout clinical research and clinical study management. A CQMS system is designed to manage all of the documents, activities ...
gives high quality DNA, RNA, Mitochondrial DNA, and source of disease Biopsy: many uses shared with blood; also suitable for proteomic analysis; may be difficult to obtain Plasma: limited DNA and RNA content Blood plasma fractionation: requires phlebotomist to collect Urine: marker for some diagnostic tests Urination: non-invasive Feces
The combination of quality control and genetic algorithms led to novel solutions of complex quality control design and optimization problems. Quality is the degree to which a set of inherent characteristics of an entity fulfils a need or expectation that is stated, general implied or obligatory. [ 1 ]
There are different definitions within laboratory quality control, wherein "analytical sensitivity" is defined as the smallest amount of substance in a sample that can accurately be measured by an assay (synonymously to detection limit), and "analytical specificity" is defined as the ability of an assay to measure one particular organism or ...
