    摘要: The present invention concerns diagnostic means and methods in the field of coagulation testing. In particular, it relates to a method for determining an anticoagulant activity elicited by a first anticoagulant in a sample of a subject comprising measuring a first Factor Xa activity in a body fluid test sample of said subject, measuring a second Factor Xa activity in at least one calibrator sample comprising a predefined anticoagulation activity for a second anticoagulant, calculating an universal parameter for the anticoagulation activity comprised in the test sample based on the first and the second measured Factor Xa activities and comparing the said parameter for the anticoagulation activity with predefined ranges of expected anticoagulation activity for at least three anticoagulants. Further provided is a computer program code assisting the method as well as a system for carrying out the said method as well as a kit.

    摘要: A hematological assay is described in which the blood coagulation potential of a body fluid is assessed by reacting a sample of the body fluid with an amount of an activator reagent comprising: (a) a predetermined amount of factor Xa or a hematologically equivalent mutant thereof, and (b) a predetermined amount of factor Va, a hematologically equivalent mutant thereof or an enzyme activating endogenous factor V, (c) (optionally) phospholipids. The reagent may be dry (e.g. lyophilised) or in an aqueous solution preferably buffered to a pH from 6 to 10 (preferably 7 to 8), if desired incubating, if necessary inducing coagulation by the addition of one or more coagulation accelerants such as calcium chloride, and establishing a value indicative of the coagulation potential, e.g. by measuring the time to clotting on an optical coagulometer or through use of a chromogenic substrate. It is preferred to use at (b) factor V activator from purified Russell's Viper venom (RVV-V). An activator reagent is also described containing the components mentioned above preferably in one or more buffer solutions or in dried, e.g. lyophilised form.

    摘要: The invention relates to a freeze-dried reagent combination containing all reagents required for determination of components active in a proteolysis such as proteases and especially proenzymes, cofactors, inhibitors and activators for proteases which reagent combination is enclosed in a container such as a cuvette. The invention also relates to a new process for the preparation of such a reagent combination in which process the conditions are controlled so that all reagents can exist in one single solution which is freeze-dried without the reagent being deactivated; and the use of the reagent combination in the fields of coagulation and fibrinolysis.

    摘要: A dynamic continuous flow enzyme reactor and method for carrying out and analyzing phospholipid-dependent enzyme reactions are provided. The enzyme reactor is a tubular member preferably a capillary tube, coated on its inner surface with a planar phospholipid bilayer membrane, optionally and preferably containing an enzyme or enzyme cofactor. The reactor is connectable at one end to a means for delivering fluid flow reagents to the reactor and is connectable at a second end to a means for analyzing an effluent exiting from the reactor. Preferably the enzyme cofactor in the phospholipid membrane is purified tissue factor and the fluid reagents are inactive blood clotting factors which become activated upon interaction with the phospholipid membrane through a tissue factor-mediated reaction.

    摘要: L'invention concerne des plasmas améliorés de régulation de la coagulation stable du sang, lesquels plasmas consistent en du plasma sanguin et en des quantités efficaces de (a) un tampon pour maintenir un pH physiologique, (b) un inhibiteur de protéase et (c) un hydrate de carbone de stabilisation appropriée. Des plasmas préférés de régulation contiennent également un azide de sodium et/ou thimerosal. Sont également décrits des plasmas de régulation stable ayant des niveaux élevés du facteur V et VIII comprenant un plasma du sang qui a été récupéré directement d'une source animale dans une solution contenant (a) un tampon pour maintenir un pH physiologique, (b) un inhibiteur de protéase et (c) un citrate et auquel, après élimination des cellules rouges, on a ajouté au moins environ 2 % d'un hydrate de carbone approprié de stabilisation, tel que le sucrose. Des procédés de préparation de plasma de régulation stable sont également décrits.
