摘要:
A method is presented for determining the concentration of an analyte in a liquid sample using a reagent system. The reaction of the sample with the reagent system results in a change of the quantity of a fluorophore, the quantity of the fluorophore correlating with the concentration of the analyte, a characteristic measurement variable for the quantity of the fluorophore being measured, and the concentration of the analyte being determined using an evaluation algorithm on the basis of the measurement variable. The reagent system is integrated in an analysis system and the fluorescence lifetime of the fluorophore is used in the ascertainment of the concentration of the analyte.

摘要:
Analysis device for determining an analyte in vivo in the body of a patient, having a measuring probe with a hollow needle (18) which can pierce through the skin. Light is passed through the hollow needle (18) and into the body via an optical fiber (22) travelling in the hollow needle (18). The light transported in the optical fiber (22) is modified in the measuring probe (3), the modification being characteristic of the presence of the analyte. A measurement and evaluation unit (4) measures the change to extract information concerning the presence of the analyte in the body. The hollow needle (18) is permeable, at least in a partial section of its length, serving as a measuring section (30) which can be inserted into the skin so that interstitial liquid may penetrate through the hollow needle wall to a measuring section of the optical fiber extending in the hollow needle (18) and the modification of the light characteristic of the presence of the analyte is effected through interaction with the interstitial liquid in the measuring section.

摘要:
In one form, a diagnostic element for determining at least one analyte is provided. In a further form, an analytical measuring device includes the diagnostic element. Still, other forms are related to methods for the determination of an analyte, correcting a signal generated by an analyte, and/or checking the detection optics of an analytical measuring device using the diagnostic element. Another form is related to a system for the controlled release of a reagent and the use of such a system as a circuit element. Other aspects include, but are not limited to, unique methods, techniques, products, systems and devices involving diagnostic elements.
