<p>A calibrator comprising at least three kinds of enzymes having enzyme activity at least two times the upper reference limit of a reference interval for respective enzyme analysis items is disclosed, and calibration curves for respective of the enzyme analysis items are corrected with the calibrator. The calibrator can be used as a control sample. According to the above procedure, apparatus differences of measured values can be reduced when an enzyme activity of a testing sample is measured. <IMAGE></p> |
