Nucleic acid (DNA or RNA) extracted from organism or virus is amplified using an enzyme. Then, the initial concentration of the nucleic acid is found by calculating the characteristic amplification cycle number or the characteristic amplification time at which the fluorescence intensity of the nucleic acid subtracted by the background fluorescence intensity of the nucleic acid has half of its maximum value, or the characteristic amplification cycle number or the characteristic amplification time at which the amplification efficiency has the maximum or the minimum value, or the prior-to-amplification fluorescence intensity of the nucleic acid subtracted by the background fluorescence intensity of the nucleic acid. Accordingly, the initial concentration of the nucleic acid can be calculated without differentiation or integration.
