Glossary of Laboratory Diagnostic Terms Accuracy Agreement between your test result value and the true value; i.

Affinity An attractive force between substances or particles that causes them to enter into and remain in chemical combination, for example; the binding of antibody to antigen.

Aggregation The grouping of units or parts into a mass or whole. Aliquot The division of a sample into at least two smaller size vials. Amplification Amplification generally means an addition to or expansion of a statement or idea. In medical terminology, amplification refers to the selective copying of a gene or any sequence of DNA.

This occurs naturally in the body in order to satisfy the increased requirement of individual cells for gene products such as proteins.

Amplification also plays a role in cancer cells when a tumour cell copies DNA segments as a result of cell signals or external environmental factors. Artificial amplification is conducted due to its central role in gene research.

Analyte The chemical substance being measured in an assay, usually contained in blood or other body fluids. Anabolic Steroid Anabolic steroids are a group of synthetic steroid hormones that promote tissue growth and the storage of protein, as such they are sometimes used in food producing animals to increase the lean meat to fat ratio.

Antibody A protein produced by our body in response to an antigen.

NIH Halts SWiTCH Study

The antibody binds to and neutralises the antigen. Anticoagulant A substance that stops the blood from clotting. Antigen Antigens are usually foreign substances which enter the body and trigger the immune system to produce antibodies in order to fight off the potential infection.

Antigens can be toxins, foreign blood cells, bacteria or the cells of transplanted organs. Antimicrobial The term given to a group of drugs that inhibits the growth or destroys microorganisms.

Antioxidant A molecule that protects cells from oxidative damage of oxygen and free radical molecules that are chemically unstable and cause random reactions damaging proteins nucleic acids and cell membranes.

Antiserum A solution of antibody or mixture of antibodies either purified or un-purified used in the manufacture of diagnostic reagents or used as a component of a diagnostic kit. Assay A diagnostic test to measure the concentration or level of a particular analyte. Assayed Assayed controls are used for the control of accuracy and reproducibility of results.

Assay Range The assay range describes the highest and lowest concentrations, at which a reaction is still measurable. Aspiration The withdrawal of fluid or tissue, e. Aqueous The term aqueous simply means dissolved in water. Avidity The average affinity of a mixture of antibody to their corresponding antigen.

B Benchtop This term simply refers to a position of an object, i. However, in a scientific setting, it is used to describe an analyser which is small enough to fit on top of a laboratory workbench but is too large to be a point of care system. Bias The term bias refers to the difference between the expected result and an accepted reference value.

Biochemistry Biochemistry is the study of the chemical structures and vital processes which occur in living organisms. Biochemists study the compounds in the body and how these result in chemical processes. They seek to understand such processes both within healthy and unhealthy organisms.

Biochip Proprietary solid substrate onto which reactive species are prefabricated for the detection of specific analytes. Individual homeostatic setting points usually vary.

This difference is known as biological variation. Biotechnology As the name suggests, this field of study is a combination of biology and technology.Open Access journals are the major source of knowledge for young and aspiring generations who are keen in pursuing a career in sciences.

This system provides easy access to networks of scientific heartoftexashop.coms that contribute their scholarly works to Open Access journals gain remarkable reputation as the research scholarly explore these works extensively. Evolution is change in the heritable characteristics of biological populations over successive generations.

These characteristics are the expressions of genes that are passed on from parent to offspring during heartoftexashop.coment characteristics tend to exist within any given population as a result of mutation, genetic recombination and other sources of genetic variation.

Botany, branch of biology that deals with the study of plants, including their structure, properties, and biochemical processes. Also included are plant classification and the study of plant diseases and of interactions with the heartoftexashop.com principles and findings of botany have provided the base for such applied sciences as agriculture, horticulture, and forestry.

Many studies have examined ‘morphometric’ neuroimaging of meditation practitioners. • We conduct a meta-analysis of these gray and white matter differences in meditators.
