Abstract
(DE)
Die Erfindung beschreibt ein Verfahren zur Stabilisierung einer flüssigen biologischen Probe mit dem Schritt des Einziehens der Probe in ein erstes Ende einer Röhre, die ein voreingestelltes Vakuum aufweist und/oder an deren gegenüberliegendem zweiten Ende ein Kolben verschieblich an einer Kolbenstange geführt ist, und die Röhre als Füllung zumindest eine Stabilisierungszusammensetzung, die in Wasser und/oder in Blutserum löslich ist und eine wässrige Stabilisierungslösung bildet, und ein Gel enthält, optional zusätzlich eine schwere wässrige Komponente, mit dem Schritt des anschließenden Zentrifugierens.
(EN)
The invention relates to a method for stabilizing a liquid biological sample, comprising the step of drawing the sample into a first end of a tube, which tube has a preset vacuum and/or at the opposite second end of which tube a plunger is slidably guided on a plunger rod, the tube containing, as a filling, at least a stabilization composition, which is soluble in water and/or in blood serum and forms an aqueous stabilization solution, and a gel, optionally additionally a heavy aqueous component, and comprising the step of subsequent centrifuging.
(FR)
L'invention décrit un procédé pour stabiliser un échantillon biologique liquide comprenant une étape de prélèvement de l'échantillon dans une première extrémité d'un tube, qui présente un vide préalablement ajusté et/ou sur la deuxième extrémité opposée duquel, un piston est guidé de manière coulissante sur une tige de piston, et le tube contient au moins une composition de stabilisation, qui est soluble dans l'eau et/ou dans le sérum sanguin et qui forme une solution de stabilisation, et un gel, le cas échéant également un composant aqueux plus lourd, avec l'étape suivante de centrifugation.
