APPARATUS, SYSTEM AND METHOD FOR ANALYZING DISEASE SAMPLE

[Problem] To elucidate a correlation between a disease and the amount of amino acid stereoisomers or the change in the amount by carrying out a total analysis of amino acid stereoisomers, leading to development of a novel method for diagnosing a disease, and a novel apparatus for diagnosing a disease in which the method for diagnosing a disease is executed.[Means for Resolution] The apparatus for analyzing a disease sample according to the present invention includes: a member for separating and quantitatively determining an amino acid stereoisomer in a biological material from a subject; a member for obtaining a disease state index value through a calculation by substituting the amount of the amino acid stereoisomer into a discriminant equation; and a member for outputting disease state information on the subject on the basis of the disease state index value. The discriminant equation may be: disease state index value = (a measurement value for an amino acid stereoisomer that correlates with the disease from among the measurement values in a biological material from the subject)/ (in a biological material from a reference value from a healthy individual), or the like. The method for analyzing a disease sample according to the present invention includes: a step of measuring the amount of amino acid stereoisomers in a biological material from a subject; a step of obtaining a disease state index value through a calculation by substituting the amount of the amino acid stereoisomers into a discriminant equation; and the like.
