Provided is a nucleic acid analysis device in which a best suited analysis method can be chosen by every user and through-put can be improved. A nucleic acid test device for measuring and analyzing an amplification reaction of a nucleic acid in real time, wherein an amplification curve is analyzed and the condition for completing the amplification reaction in the detection of the amplification can be chosen by a user. Further, the condition for selecting a subsequent processing after the completion of the amplification reaction can be chosen by a user. The condition for completing the amplification reaction and the condition for selecting a subsequent processing can be chosen by a user on the scene during the detection of the amplification or after the completion of the amplification reaction. Alternatively, the condition for completing the amplification reaction and the condition for selecting a subsequent processing may be registered in advance and the processing may be performed automatically during the detection of the amplification and after the completion of the amplification reaction.
