Abstract: An improved quality assurance system and method for point-of-care testing are disclosed. The present invention provides quality assurance for laboratory quality tests performed by a blood analysis system or the like at the point of patient care without the need for running liquid-based quality control materials on the analysis system. Quality assurance of a quantitative physiological sample test system is performed without using a quality control sample by monitoring the thermal and temporal stress of a component used with the test system. Alert information is generated that indicates that the component has failed quality assurance when the thermal and temporal stress exceeds a predetermined thermal-temporal stress threshold. Alternatively, the present invention provides quality assurance for laboratory quality tests performed by a blood analysis system or the like at the point of patient care by minimizing the need for running liquid-based quality control materials on the analysis system.

Abstract: An automatic method for identifying biological samples that are collected using the wrong blood preservative for subsequent analytical testing. The method also provides for identification and/or suppression of certain analytical test results that are substantially or partly adversely affected. The invention is particularly suited for use in point-of-care medical diagnostic testing.

Abstract: One aspect of the present invention is concerned with a composition comprising caramelised carbohydrate, which composition, when dissolved in water at a dry solids content of 0.1 wt. %, exhibits: i. an absorption at 280 nm (A280) that exceeds 0.01, preferably exceeds 0.05, more preferably exceeds 0.1 and most preferably exceeds 0.3; and ii. an absorption ratio A280/560 of at least 200, preferably of at least 250. Other aspects of the invention relate to a method of manufacturing a beverage or foodstuff that is resistant to light induced flavour changes, said method comprising introducing into said beverage or foodstuff a composition as defined above; and to a process for the manufacture of said composition.

Abstract: One aspect of the present invention is concerned with a composition that can suitably be used as an additive in beverages and foodstuffs, which composition: i. contains at least 0.5%, preferably at least 1.0%, by weight of dry matter, of pyrazine derivatives according to formula (I): wherein R1-R4 independently represent hydrogen; a hydroxyhydrocarbyl residue; an ester of a hydroxyhydrocarbyl residue; or an ether of a hydroxyhydrocarbyl residue; and at least one R1-R4 is a hydroxyhydrocarbyl residue or an ester or an ether thereof, and ii. exhibits an absorption ratio A280/560 of at least 80, preferably of at least 250. The invention also relates to a method of manufacturing a beverage or a foodstuff that is resistant to light induced flavour changes, said method comprising introducing into said beverage or foodstuff the aforementioned light stabilising composition and to a process for the manufacture of such a light stabilising composition.
