Abstract: The present invention is to provide a method for analyzing a target nucleic acid, by which the target nucleic acid can be analyzed rapidly and easily. In order to achieve the above object, the present invention provides a method for analyzing a target nucleic acid in a sample, including the step of: analyzing the target nucleic acid in the sample by bringing the sample into contact with a label and with a primer or probe that can hybridize to the target nucleic acid. The primer or probe is immobilized on a solid phase. The label does not emit light when the primer or probe does not hybridize to the target nucleic acid, whereas the label emits light when the primer or probe has hybridized to the target nucleic acid. The analysis is carried out by detecting the light emitted from the label.

Abstract: The present invention is to provide a pretreatment method that allows RNA to be detected promptly and simply. RNA degradation activity due to lactoferrin present in the human rhinal mucosa is inhibited, for example, by adding iron ion and carbonate ion to a biological sample that contains the human rhinal mucosa. With the pretreated biological sample, an RNA virus gene can be amplified by a reverse transcriptase. Iron ion and carbonate ion can also inhibit reverse transcriptase inhibition due to lysozyme C contained in the human rhinal mucosa. Further, it is preferable to remove the envelope of the RNA virus by adding SDS to the biological sample that contains the human rhinal mucosa.
