biochemical oxygen demand; biological oxygen demand; BOD; B. O. D. :[These terms and abbreviations can also refer] to a chemical procedure for determining this amount. This is not a precise quantitative test, although it is widely used as an indication of the organic quality of water. The BOD value is most commonly expressed in milligrams of oxygen consumed per litre of sample during 5 days of incubation at 20 °C and is often used as a robust surrogate of the degree of organic pollution of water.... BOD can be used as a gauge of the effectiveness of wastewater treatment plants.... BOD is similar in function to chemical oxygen demand(COD), in that both measure the amount of organic compounds in water. However, COD is less specific, since it measures everything that can be chemically oxidized, rather than just levels of biologically active organic matter.  2, record 1, English, - biochemical%20oxygen%20demand

Tests sérologiques de la syphilis [...] Il existe trois tests tréponémiques standard [dont] l'immunofluorescence (FTA-ABS)[.] Pour le test FTA-ABS, le sérum du malade est d'abord dilué avec une substance contenant des antigènes tréponémiques non pathogènes (absorbant) pour éliminer les anticorps spécifiques de groupe dirigés contre les tréponèmes saprophytes des cavités buccales et génitales. Le sérum ainsi absorbé est alors déposé sur une lame recouverte de T. [Treponema] pallidum fixés. Si l'anticorps spécifique de T. Pallidum est présent dans le sérum du patient, il se fixe aux tréponèmes séchés; sa mise en évidence se fait alors par l'adjonction d'anti-immunoglobulines humaines marquées à la fluorescine et examen de la lame au microscope à fluorescence. [...] le FTA-ABS [est un test très spécifique, et lorsqu'il est utilisé] pour confirmer des réactions réaginiques positives, [il a] une très haute valeur prédictive positive pour le diagnostic de la syphilis.  4, record 2, French, - test%20FTA%2DABS

The failure of gas to form after incubation is called a negative test. The appearance of gas and the accompanying cloudiness in the broth is called a positive presumptive test. There are some bacteria other than coliforms that occasionally produce gas in lactose. Because of this, it is usually necessary to perform another test, called the confirmed test, to prove that it was really the coliform bacteria that produced the gas in the positive presumptive tube.... In some cases, a third procedure, called the completed test, may have to be performed.  1, record 4, English, - completed%20test

Recently, the fluoroallergosorbent test has been introduced into the clinical practice in order to make the IgE determination both quick and safe.... method described by Seltzer et al. In brief, this consists of the following procedure : 100[ mu] L of serum are added to a microtiter well-coated with allergen. After a short incubation, non-specific IgE is removed by washing and specific IgE bound to an enzyme-labeled monoclonal anti-human IgE. Following a short incubation and washing step, a fluoregenic substratum is added and the fluorescence signal read by a rapid fluorometer within 30 seconds.  1, record 5, English, - fluoroallergosorbent%20test

Photographic activity test. The paper and a suitably prepared photographic test sample are to be subjected to an accelerated ageing test by incubation at 50 plus or minus 1 degree C and at 74 plus or minus 2% relative humidity for 10 days. At the end of this test, no visual pattern shall be transferred from the paper to the photographic plate, nor shall the image of the plate be affected. The latter may be determined more readily by having one-half of the photographic image against a piece of filter paper during the incubation to serve as a control.  1, record 7, English, - photographic%20activity%20test
