Abstract: A method for determining the amount of specific analyte of a sample which may show interferences by photometric assays, wherein the analyte is quantified from the change in the optical signal of the reaction mixture after the interaction of the analyte with analyte specific reagents. Multiple calibration curves are generated for multiple wavelengths for the specific analyte. An interference test is performed simultaneously to the determination of the specific analyte, for quantifying the amount of interfering substances present in the sample. The amount of each interfering substances is compared to predetermined cut-off values. The optical signal for the specific analyte is measured in the reaction mixture at multiple wavelengths over the complete reaction time, and a calibration curve is selected depending on the interfering substances. The amount of specific analyte is quantified by comparison with the selected calibration curve for the chosen wavelengths.

Abstract: A method for determination of the amount of a specific analyte in a sample which may show a prozone effect by photometric assays, wherein the specific analyte is quantified from the change in the optical signal of the reaction mixture after the interaction of the analyte with analyte specific assay reagents. The optical signal is measured simultaneously for the specific analyte in the sample to be determined at the wavelength used for the determination of the analyte and at least at an additional specific wavelength used for the detection of the prozone effect over the complete reaction time. The reaction rate ratio R is calculated by using the signals obtained at the wavelength used for the detection of the prozone effect. By comparison of the calculated ratio value R with predetermined limit values it is judged if a prozone effect is present in the sample.
