Definition von bioassay im Englisch Englisch wörterbuch: the analysis of the biological activity of a substance, with reference to a standard preparation, using a culture of living cells, or a living creature; A test used to determine such strength or activity; Determination of the strength or biological activity of a substance, such as a drug or hormone, by comparing its effects with those of a standard preparation on a culture of living cells or a test organism; Using living organisms to measure the effect of a substance, factor, or condition; A determination of the concentration of a substance in the body by the analysis of urine, blood, feces, bone, or tissue The use of the living organism to measure the amount of a substance that has been absorbed; The quantitative evaluation of the potency of a substance by assessing its effects on tissues, cells, live experimental animals, or humans See also assay; The inoculation of tissue into another animal in order to see if it is infective (if it is, the animal will develop disease) Multiple dilutions of the inoculum will, if the dilutions are enough, get to the point that not enough infection is present in the inoculum to cause disease The lowest amount of inoculum that will still transmit the disease is said to contain one infective unit; appraisal of the biological activity of a substance by testing its effect on an organism and comparing the result with some agreed standard; the determination of the activity or concentration of a chemical by its effect on the growth of an organism under experimental conditions [CUB]; subject to a bio-assay; A method of determining the effect of a compound by quantifying its effect on living organisms or their component parts; A measurement of the effects of a substance on living organisms; Procedure which tests the strength of a substance by testing its effects on a living organism under standardized conditions; Study of living organisms to measure the effect of a substance, factor, or condition by comparing before-and-after exposure or other data; Determination of the potency or concentration of a compound by its effect upon animals, isolated tissues, or microorganisms, as compared with an analysis of its chemical or physical properties; {i} determining of the biological function of a substance by examining its influence on the growth of organisms; An assay for determining the potency (or concentration) of a substance that causes a biological change in experimental animals; A laboratory test that uses organisms to evaluate whether a sample is toxic; "Bioassay" means a test procedure that measures the response of plants or animals, or their tissues, to hazardous substances present in the soil; Determining the physiological effect of a substance (such as a drug) by comparing its effects on a test tissue, organ, or living organism with that of some standard substance; in contrast to chemical assay or analysis; Exposing test organisms to samples (of water, sediment etc) and comparing their response with organisms exposed to control or reference treatment; A test used to evaluate the relative potency of a chemical or mixture of chemicals by comparing its effect on a living organism with the effect of a standard preparation on the same organism Bioassays are frequently used in the pharmaceutical industry to evaluate the potency of vitamins and drugs; The determination of kinds, quantities or concentrations, and in some cases, the locations, of radioactive material in the human body, whether by direct measurement (in vivo counting) or by analysis and evaluation of materials excreted or removed (in vitro) from the human body; Determination of the quantity, type and location of radioactive material in the human body by direct measurement or by analysis of materials excreted or removed from the body; The inoculation of an infective substance into another animal in order to see if the second animal develops the same disease Different dilutions of tht infective substance are used to assess how infective the substance is; appraisal of the biological activity of a substance by testing its effect on an organism and comparing the result with some agreed standard subject to a bio-assay; Determination of the effectiveness of a compound by measuring its effect on animals, tissues or organisms in comparison with a standard preparation; an assay method using a change in biological activity as a qualitative or quantitative means of analyzing a material response to industrial waste and other wastewater by using viable organisms or live fish as test organisms; Determination of the effectiveness of a compound by measuring its effect on animals, tissues, or organisms in comparison with a standard preparation; Using living organisms to measure the effect of a substance, factor, or condition by comparing before-and-after data; A study of a living organism to measure the effect of a substance, factor, or condition
