Claim Text:
1. A method for preparing a nucleic acid amplification sample, the method consisting essentially of: adding at least one anionic surfactant to a biological sample to obtain a nucleic acid extract, wherein the at least one anionic surfactant is selected from the group consisting of an allcylsulfuric acid salt, an alkyl ethersulfuric acid salt and an alkylbenzenesulfuric acid salt; and contacting the nucleic acid extract with a zeolite to absorb substances in the nucleic acid extract; and separating a solution comprising nucleic acid from the substances absorbed on the zeolite to obtain a nucleic acid amplification sample, wherein the zeolite is a protonated zeolite having a mordenite crystal structure, wherein the biological sample is blood, spinal fluid, urine, feces, expectorate, saliva, nasal discharge or swabbed fluid.
