Abstract
An immunoanalytical system in which, after a sample such as a patient's serum is subjected to a pretreatment by an immunological pretreatment device, the sample is subjected to light detection by an immunological photometric detection system. Subsequently, the mass spectrometric pretreatment device performs a pretreatment, and the mass spectrometric detection system performs mass spectrometry. The mass spectrometric detection system performs mass spectrometry on components contained in a supernatant. A signal intensity and peak area for each of components are calculated from an obtained chromatograph. A quantitative value measured based on the immunoanalytical method is calculated for each of the components on the basis of the relative ratios of the components.
