A DNA amplification method including: subjecting a blood sample having DNA to be amplified, to a pretreatment using an alkaline aqueous solution under ordinary temperature, so as to extract double-stranded DNA from the blood sample and dissociate the double-stranded DNA into a single-stranded DNA to obtain a blood-derived sample including the single-stranded DNA; preparing an isothermal amplification reaction solution comprising a mixture of the blood-derived sample, a primer, dNTP, a strand-displacing DNA polymerase, a magnesium salt and a buffer, to establish an isothermal amplification reaction system meeting optimum conditions for the strand-displacing DNA polymerase; and amplifying DNA in the isothermal amplification reaction system using the single-stranded DNA as a template. |
