Ringtest
{{unreferenced, date=October 2010 A ringtest for quality management is part of an external quality assurance programme for a measuring method. Ringtest is also called proficiency test or interlaboratory test. Usually a reference institute sends identical samples which have to be analyzed for special parameters to different laboratories. The industrial, medical or research laboratory gets a limited time with a deadline to send in the analysis results. The statistical evaluation and interpretation of the laboratories’ results is a great help for all participating labs as it opens the possibility to assess the quality of their analysis compared to other laboratories. Participation in ringtests is obligatory for accredited laboratories (e.g. according to ISO 17025, etc.). Nevertheless, non-accredited laboratories can also take part in ringtests. Fields of application * tests of medical parameters (blood, urine, tissue etc.) * food analysis * environmental analysis (soil, plants, fres ...

Quality Management
Quality management ensures that an organization, product or service consistently functions well. It has four main components: quality planning, quality assurance, quality control and quality improvement. Quality management is focused not only on product and service quality, but also on the means to achieve it. Quality management, therefore, uses quality assurance and control of processes as well as products to achieve more consistent quality. Quality control is also part of quality management. What a customer wants and is willing to pay for it, determines quality. It is a written or unwritten commitment to a known or unknown consumer in the market. Quality can be defined as how well the product performs its intended function. Evolution Quality management is a recent phenomenon but important for an organization. Civilizations that supported the arts and crafts allowed clients to choose goods meeting higher quality standards than normal goods. In societies where arts and crafts ...

Quality Assurance
Quality assurance (QA) is the term used in both manufacturing and service industries to describe the systematic efforts taken to ensure that the product(s) delivered to customer(s) meet with the contractual and other agreed upon performance, design, reliability, and maintainability expectations of that customer. The core purpose of Quality Assurance is to prevent mistakes and defects in the development and production of both manufactured products, such as automobiles and shoes, and delivered services, such as automotive repair and athletic shoe design. Assuring quality and therefore avoiding problems and delays when delivering products or services to customers is what ISO 9000 defines as that "part of quality management focused on providing confidence that quality requirements will be fulfilled". This defect prevention aspect of quality assurance differs from the defect detection aspect of quality control and has been referred to as a ''shift left'' since it focuses on quality effor ...

Laboratory
A laboratory (; ; colloquially lab) is a facility that provides controlled conditions in which scientific or technological research, experiments, and measurement may be performed. Laboratory services are provided in a variety of settings: physicians' offices, clinics, hospitals, and regional and national referral centers. Overview The organisation and contents of laboratories are determined by the differing requirements of the specialists working within. A physics laboratory might contain a particle accelerator or vacuum chamber, while a metallurgy laboratory could have apparatus for casting or refining metals or for testing their strength. A chemist or biologist might use a wet laboratory, while a psychologist's laboratory might be a room with one-way mirrors and hidden cameras in which to observe behavior. In some laboratories, such as those commonly used by computer scientists, computers (sometimes supercomputers) are used for either simulations or the analysis of data. Scient ...

Blood
Blood is a body fluid in the circulatory system of humans and other vertebrates that delivers necessary substances such as nutrients and oxygen to the cells, and transports metabolic waste products away from those same cells. Blood in the circulatory system is also known as ''peripheral blood'', and the blood cells it carries, ''peripheral blood cells''. Blood is composed of blood cells suspended in blood plasma. Plasma, which constitutes 55% of blood fluid, is mostly water (92% by volume), and contains proteins, glucose, mineral ions, hormones, carbon dioxide (plasma being the main medium for excretory product transportation), and blood cells themselves. Albumin is the main protein in plasma, and it functions to regulate the colloidal osmotic pressure of blood. The blood cells are mainly red blood cells (also called RBCs or erythrocytes), white blood cells (also called WBCs or leukocytes) and platelets (also called thrombocytes). The most abundant cells in vertebrate blo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Urine
Urine is a liquid by-product of metabolism in humans and in many other animals. Urine flows from the kidneys through the ureters to the urinary bladder. Urination results in urine being excretion, excreted from the body through the urethra. Cell (biology), Cellular metabolism generates many by-products that are rich in nitrogen and must be clearance (medicine), cleared from the Circulatory system, bloodstream, such as urea, uric acid, and creatinine. These by-products are expelled from the body during urination, which is the primary method for excreting water-soluble chemicals from the body. A urinalysis can detect nitrogenous wastes of the mammalian body. Urine plays an important role in the earth's nitrogen cycle. In balanced ecosystems, urine fertilizes the soil and thus helps plants to grow. Therefore, Reuse of excreta, urine can be used as a fertilizer. Some animals use it to territory (animal)#Scent marking, mark their territories. Historically, aged or fermented urine (kn ...

Biological Tissue
In biology, tissue is a biological organizational level between cells and a complete organ. A tissue is an ensemble of similar cells and their extracellular matrix from the same origin that together carry out a specific function. Organs are then formed by the functional grouping together of multiple tissues. The English word "tissue" derives from the French word "tissu", the past participle of the verb tisser, "to weave". The study of tissues is known as histology or, in connection with disease, as histopathology. Xavier Bichat is considered as the "Father of Histology". Plant histology is studied in both plant anatomy and physiology. The classical tools for studying tissues are the paraffin block in which tissue is embedded and then sectioned, the histological stain, and the optical microscope. Developments in electron microscopy, immunofluorescence, and the use of frozen tissue-sections have enhanced the detail that can be observed in tissues. With these tools, the c ...

Paternity (law)
Paternity law refers to body of law underlying legal relationship between a father and his biological or adopted children and deals with the rights and obligations of both the father and the child to each other as well as to others. A child's paternity may be relevant in relation to issues of legitimacy, inheritance and rights to a putative father's title or surname, as well as the biological father's rights to child custody in the case of separation or divorce and obligations for child support. Under common law, a child born to a married woman is presumed to be the child of her husband by virtue of a "presumption of paternity" or presumption of legitimacy. In consideration of a possible non-paternity event (which may or may not include paternity fraud) these presumptions may be rebutted by evidence to the contrary, for example, in disputed child custody and child support cases during divorce, annulment or legal separation. In the case of a father not married to a child's mot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gednap
GEDNAP is the acronym for ''German DNA Profiling'' and was used in the early nineties in analogy to EDNAP (''European DNA Profiling'', a working group of the International Society for Forensic Genetics (ISFG) for the first time in the course of the proficiency tests organized by the German Stain Commission, a Joint Commission of University Institutes of Legal Medicine and Police Institutes of Forensic Sciences in Germany. After the introduction of DNA markers Prof. Bernd Brinkmann, at that time the director of the Institute of Legal Medicine in Münster (Germany) was appointed by the Stain Commission as Director of the GEDNAP proficiency testing scheme. After his retirement in 2007 Bernd Brinkmann founded the ''Institute of Forensic Genetics'', serving as managing director of the GEDNAP Proficiency test program. Since 2023 the GEDNAP proficiency tests are organized by the ''Institute of forensic molecular genetics, based in Emsdetten.'' From 2010 until his death in 2022, Prof. Pet ...
