Abstract: Procedimiento para la determinación de inhibidores de factor Xa en muestras de sangre, caracterizadoporque a) una muestra de la sangre a analizar es puesta en contacto con un reactivo de detección, que contiene, como mínimo, un sustrato de trombina, que está constituido por un residuo peptídico, que puede ser disociado por latrombina y que está unido amídicamente con intermedio del extremo carboxilo a una sustancia electrogénica y conun reactivo que contiene una cantidad conocida de factor X y un reactivo activador, que provoca la transformaciónde factor X en factor Xa, de manera que la adición del reactivo que contiene una cantidad conocida de factor X a lamuestra tiene lugar en una etapa común con la adición del reactivo activador a la muestra, b) la cantidad o la actividad de la sustancia electrogénica que es disociada del sustrato de trombina por laactivación de la trombina inducida por el factor Xa y/o su comportamiento en el tiempo se determinan como señal demedición por procedimientos electroquímicos, y c) con ayuda de esta señal de medición, se determina la cantidad de inhibidor de factor Xa en la muestra desangre a analizar o una magnitud de medición correlacionada con aquélla, en particular un tiempo de coagulaciónque se correlaciona con éste.

Abstract: The invention concerns methods and devices for determining factor Xa inhibitors in particular heparins and fractionated or low-molecular-weight heparins as well as direct factor Xa inhibitors in blood samples which are characterized in that in a first step the blood sample is brought into contact with a detection reagent which contains at least one thrombin substrate which consists of a peptide residue that can be cleaved by thrombin and is amidically bound via the carboxyl end to an electrogenic substance, and with a known amount of factor X reagent and an activator reagent which induces the conversion of factor X into factor Xa, subsequently in a second step the amount or activity of the electrogenic substance which is cleaved from the thrombin substrate by the factor Xa-mediated thrombin activation and/or the time course thereof is determined as the measurement signal using electrochemical methods, and finally in a third step the amount of the factor Xa inhibitor in the sample of the blood to be analysed or a measured quantity that correlates therewith, in particular a clotting time that correlates therewith, is determined on the basis of this measurement signal.

Abstract: The invention relates to a portable diagnostic measurement device for determining at least one analysis parameter of a bodily fluid, in particular for determining an analyte concentration in a bodily fluid and particularly preferably for blood glucose determinations, and to an analysis system which comprises the measurement device and at least one disposable (to be used one time) testing element. The testing element, designed as a carrier strip, contacts a receiving surface of the diagnostic measurement device at least partially in a flat manner, wherein the receiving surface is arranged on a narrow side of the housing of the measurement device.
