It is provided a measuring cartridge () for measuring at least one constituent of a liquid sample, in particular blood, and for performing quality control, the cartridge comprising: a casing () insertable into a reception opening () of a measuring instrument (), the casing () at least partly surrounding an inner space (); wherein the inner space contains: a measurement cell () comprising a reception space () for the sample and at least one sensor area () with which the sample is in contact when loaded into the reception space (); plural quality control containers () for respectively holding different quality control solutions (); a solution routing system () adapted to selectively route one of the quality control solutions () from the respective quality control container () into the reception space () of the measurement cell ().

Measuring cartridge for measuring a liquid sample

In a method for calibrating a biosensor for the amperometric determination of creatinine in biological liquids, consisting of one electrode system each for measuring the concentrations of creatinine and creatine, with at least two calibration solutions being used, the electrode system for measuring the creatinine concentration is calibrated with a creatinine solution which, prior to the calibration measurement, was mixed in the form of an acidic solution with an alkaline buffer solution, and the electrode system for measuring the creatine concentration is calibrated with a solution in which creatinine and creatine are at a thermodynamic equilibrium.
