  • Patent number: 10809258
    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.

  • Patent number: 10809273
    Abstract: A method of determining an analyte concentration in a sample by a sensor is disclosed. The method includes analyzing a sample signal generated by the sensor for an analyte being measured. If the sample signal is normal, the method includes comparing the sample signal with a first reference signal of a reference solution measured prior to measuring the sample in order to determine the analyte concentration. If the sample signal is abnormal, the method includes comparing the sample signal with a calculated reference signal point obtained by interpolation between the first reference signal and a second reference signal of the same reference solution measured after measuring the sample. Various methods of determining and handling errors based on signal patterns are also disclosed.
