Nucleic acid analysis device, and nucleic acid analysis method

A nucleic acid analysis device comprising:

• a distribution unit;
• a labeling unit;
• an information acquisition unit;
• and
• an information processing unit,
• wherein the information processing unit includes:
• an information extraction unit;
• an artifact component determination unit;
• a correction unit;
• and
• an identifying unit,
• wherein the distribution unit is configured to distribute a sample including nucleic acid and a reagent to a plurality of individual separated compartments to form a set including the plurality of individual separated compartments and a portion other than the plurality of individual separated compartments,
• wherein the labeling unit is configured to cause a change in each of the plurality of individual separated compartments to which the sample including target nucleic acid is distributed so that the each of the plurality of individual separated compartments to which the sample including target nucleic acid is distributed and each of the plurality of individual separated compartments to which a sample excluding target nucleic acid is distributed are distinguishable from each other by the identifying unit,
• wherein the information acquisition unit is configured to acquire information corresponding to the set,
• wherein the information extraction unit is configured to extract, from the acquired information corresponding to the set, each of information corresponding to the plurality of individual separated compartments and information corresponding to the portion other than the plurality of individual separated compartments,
• wherein the artifact component determination unit is configured to determine an artifact component from the extracted information corresponding to the portion other than the plurality of individual separated compartments,
• wherein the correction unit is configured to use the artifact component to correct the extracted information corresponding to the plurality of individual separated compartments, and
• wherein the identifying unit is configured to identify, based on the corrected information corresponding to the plurality of individual separated compartments, each of the plurality of individual separated compartments in which a magnitude of the change exceeds a predetermined threshold.
