Method and apparatus for measuring blood sugar
First Claim
1. A method for measuring the concentration of a substance in a liquid, especially for blood sugar measurement, the method comprising the steps of:
- applying a liquid to a measuring field including a hydrophilic area of a test strip, measuring the optical reflectivity or transmissivity in the measuring field, comparing the measured value of the optical reflectivity or transmissivity in the measuring field at a pre-given time with a reference value, and activating an indicator if a relationship between the measured value and the reference value exceeds a pre-given threshold value.

Abstract
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.

8. A method for measuring the concentration of a substance in a liquid, especially for blood sugar measurement, the method comprising the steps of:
- applying a liquid to be measured to a measuring field of a test strip, measuring the optical reflectivity or transmissivity in the measuring field effected by the liquid, the step of measuring including taking a plurality of measurements in the measuring field within a pre-determined period of time and comparing each measured value with the measured value taken a given number of measurements previously, and activating an indicator when the measured value exceeds the comparison measured value.
