Method for controlling a photometric measuring unit of a measuring device for generating and examining a body liquid sample and measuring system

摘要

The method involves illuminating a test field (1) that is wetted with a body fluid sample. Light is delivered to a detector of a measuring unit from a measuring surface (3), where the unit comprises a LED. The measuring surface is displaced to and beyond a partial surface (2) that is wetted by the sample. An extreme value is detected, in course of a detector signal. The measuring surface is brought in a position, in which the extremal detector signal is measured. The position of the measuring surface, in which the signal is extremal, is utilized for photometric concentration measurement. An independent claim is also included for a measuring system for photometric determination of analyte concentration in a body fluid sample.
