Claim One:
1. Method for determining a normalized concentration or activity of an analyte in a sample, including a respective confidence information, the method comprising: a) determining one or more measurement values representative of the concentration or activity of the analyte from the sample, b) determining one or more measurement values representative of the concentration or activity of at least one reference substance from said and/or other samples, c) obtaining an estimation by using an estimator of true or related values and respective confidence information for said estimate for the concentration or activity of the analyte and the at least one reference substance from the measurements in a) and b), d) obtaining an estimation by using an estimator of a normalized value and respective confidence information for said estimate representative of the concentration or activity of the analyte from values in a), b) and c), wherein the normalized value and respective confidence information is bounded from below, above or both, wherein the confidence information from d) is used to determine a quality control criterion for said determination of the concentration or activity of the analyte.
