Abstract: The method for generating an index for managing the analytical accuracy of a sample analyzer includes a step of acquiring a determination result related to whether a sample is positive or negative from a plurality of sample analyzers, and a step of generating an index based on a ratio of a sample determined to be positive or negative by the plurality of sample analyzers from a plurality of determination results obtained from the plurality of sample analyzers.

Abstract: Disclosed is a measurement method for measuring a test substance contained in a biological sample based on a predetermined measurement principle, comprising acquiring a first measured value of the test substance using a first measurement reagent, and operating the first measured value to an arithmetic value when measured using a second measurement reagent different from the first measurement reagent, by using arithmetic information designed to make a first cut-off value for the measured value obtained using the first measurement reagent correspond to a second cut-off value for a measured value obtained using the second measurement reagent.

Abstract: A method and apparatus for judging the presence or absence of metastasis of malignant tumor is herein described. The method comprising: measuring an absolute amount of a tumor marker; and judging the presence or absence of metastasis of malignant tumor by comparing the absolute amount with a predetermined threshold value. The apparatus comprising: a measuring assembly for obtaining information related to an absolute amount of a tumor marker; and a computer for obtaining absolute amount of the tumor marker based on the information related to the absolute amount of the tumor marker, and judging the presence or absence of metastasis by comparing the absolute amount of the tumor marker with a predetermined threshold value.

Abstract: A probe set is described that includes a first probe having a target-binding substance and a base sequence X1, a second probe having a base sequence X2c and a base sequence X1c hybridizable with the base sequence X1, and a third probe having a base sequence X2 hybridizable with the base sequence X2c. A method for detecting a target substance is also described.

Abstract: The present invention relates to a primer and method for detecting lymph node metastasis of a cancer cell derived from a colon cancer by detecting a marker in a sample prepared from a lymph node obtained from a living body, wherein the marker is a mRNA or a fragment of the mRNA, the mRNA being transcribed from a gene coding a specific protein.

Abstract: A method for detecting a target substance is described, which comprises the steps of: forming a first complex comprising (a) a first nucleic acid probe immobilized on a first solid phase and having a single-strand portion, (b) a nucleic acid ligand which has a binding section as a base sequence hybridizable with the single-strand portion of the first nucleic acid probe and which has a target-binding substance capable of binding to the target substance, (c) the target substance, and (d) a labeling substance capable of binding to the target substance; separating, from the first complex, a second complex comprising the nucleic acid ligand, the target substance and the labeling substance; and detecting the target substance on the basis of the labeling substance in the second complex.

Abstract: A genetic testing method for specifically amplifying a DNA complementary to a target nucleic acid existing in a biologic sample, measuring the amplified DNA, and generating diagnosis support information on the basis of a measurement result is described that includes steps of: (a) specifically amplifying a DNA complementary to an internal standard nucleic acid by using a known amount of the internal standard nucleic acid in the absence of the biologic sample component, and obtaining a first measurement result on the basis of the amplification, wherein the DNA has a property to be specifically amplified in the presence of the biologic sample component; (b) specifically amplifying the DNA complementary to the target nucleic acid in the presence of the biologic sample component, and obtaining a second measurement result on the basis of the amplification; and (c) comparing the first and second measurement results to obtain diagnosis support information.
