METHOD FOR VERIFYING FITNESS OF AN ANALYSIS ELEMENT
First Claim
1. A method for verifying the usability of a test element provided for use with a corresponding evaluation unit for analysis of a liquid sample, the method comprising the steps of:
- a) determining a first standard value for at least one control parameter measured from a standard reference presented to the evaluation unit, the standard reference providing a standardized reference value for the at least one control parameter;
b) providing a first test element comprising a first test field to the evaluation device and determining a blank-field reference value for the at least one control parameter from the first test field;
c) calculating a first ratio from the reference value and the first standard value;
d) providing a second test element comprising a second test field to the evaluation device and determining a blank-field control value for the at least one control parameter from the second test field;
e) calculating a second ratio from the control value and the first standard value;
f) determining a deviation between the second ratio and the first ratio; and
g) rejecting the second test element if the deviation is not within a pre-determined tolerance range for the deviation.

Abstract
The present invention pertains to a method for verifying usability of a test element on the basis of the relation of at least one control parameter measurable from the blank test field of a test element to a standard value for the at least one control parameter. In one embodiment, the method comprises determining the deviation between a first ratio calculated from a blank-field reference value measured for the control parameter and a first standard value, and a second ratio calculated from a blank-field control value and the first standard value, and rejecting a test element if the deviation is not within a predetermined tolerance range for the deviation.
