Described is a method of sampling a body fluid of a patient. The method includes providing a fluid handling system having one or more fluid passageways (20). The method further includes infusing an infusion fluid by way of a fluid handling system into a patient through one or more fluid passageways. The method further includes obtaining a sample of body fluid by way of a fluid handling system from a patient through one or more fluid passageways. The obtained sample is no more than 400 microliters in volume. The method further includes analyzing at least an analyzed portion of the obtained sample by way of an analyte detection system (324) operatively associated with the fluid handling system to determine a concentration of at least one analyte. A corresponding system is also disclosed.

Dans certains modes de réalisation, une méthode permet d'échantillonner un liquide organique d'un patient. Ladite méthode consiste à fournir un système d'administration de liquide possédant au moins une voie de passage pour liquide (20). La méthode consiste à perfuser, au moyen dudit système d'administration de liquide, un patient et à lui administrer un liquide de perfusion par l'intermédiaire d'au moins une voie de passage de liquide. Par ailleurs, cette méthode consiste à obtenir un échantillon de liquide organique d'un patient, à l'aide du système d'administration, via au moins une voie de passage de liquide. L'échantillon obtenu ne correspond pas à plus de 400 microlitres du volume. Ladite méthode consiste, ensuite, à analyser au moins une partie analysée de l'échantillon obtenu au moyen d'un système de détection d'analyte (324) lié fonctionnellement au système d'administration de liquide, afin de déterminer une concentration d'au moins un analyte. Cette invention a aussi trait à un système associé.
