Abstract
For a simple and reliable check of the fitness for purpose of analysis elements, it is proposed to check the deviation of the quotient of a control value and a first standard reference value as compared to a first reference quotient, formed by a control reference value and the first standard reference value, and to reject a checked analysis element, if the deviation is not within a given tolerance range.

Method for checking the fitness for purpose of analysis elements, in which method it is checked, whether a control value measured for at least one control parameter of a checked analysis element is within a tolerance range,
- wherein
- a) in a first step, a first standard reference value is determined in a reference value measurement at a reference control means which provides a standardized reference value for the control parameter,
- b) in a second step, the control parameter of a first analysis element is determined as control reference value,
- c) in a third step, the quotient from the control reference value and the first standard reference value is calculated and set as first reference quotient for analysis elements measured later,
- d) in a fourth step, the control parameter of a second analysis element is determined as control value for the second analysis element to be checked,
- e) in a fifth step, the quotient from the control value and the first standard reference value is calculated as the control quotient,
- f) in a sixth step, the deviation between the control quotient and the first reference quotient is determined and
- g) the checked second analysis element is rejected if the deviation is not within a given tolerance range.
