Abstract

According to one embodiment, a method of quantifying a target nucleic acid containing a first sequence in a sample is provided. The method includes preparing a substrate on which a plurality of detection regions are arranged, forming a reaction field by placing, on the substrate, a reaction liquid containing a sample, a primer set, and an amplification enzyme, maintaining the reaction field in an isothermal amplification condition, detecting a detection signal for each of the detection regions, determining, for each of the plurality of detection regions, whether positive or negative and detecting or quantifying the target nucleic acid based on the number of positive and/or a rise time of each of the positive detection signal.
