A strip ejector removes a longitudinal test strip (), which has at least one test field for wetting by a fluid, from a measuring device that optically or amperemetrically measures such test strip. The ejector includes a clamping jaw holder (), and at least two clamping jaws () arranged on the clamping jaw holder at a distance from one another. The jaws are moveable relative to one another between a freeing position in which the spacing between their clamping surfaces is larger than the width of a test strip (), and a clamping position in which their clamping faces respectively engage parallel edges () of the test strip (). An actuating element () moveably supported on the clamping jaw holder () has at least one control surfacearranged at an angle to the movement direction of the actuating element. The control surface cooperates with a countersurface () formed on a least one of the clamping jaws () to move the clamping jaw () from its freeing position to its clamping position upon a movement of the actuating element ().

In a method for the measurement of the concentration of a substance in a liquid, especially for blood sugar measurement, the liquid to be measured is applied to the measuring field of a test strip, which measuring field is composed of a hydrophilic material, and the change of the optical reflectivity or transmissivity effected thereby in the area of the measuring field is captured. A measured value taken after a pre-given time is compared with a reference value and an indication is made if a relationship of the measured value to the reference value exceeds a pre-given threshold value.
