Coronavirus quality control diluent as well as preparation method and application thereof

The invention relates to a coronavirus quality control diluent as well as a preparation method and application thereof, and relates to the technical field of detection. The diluent comprises a buffer solution, an RNA enzyme inhibitor, a virus metabolism inhibitor, an RNA stabilizer and a bacteriostatic agent, wherein the RNA stabilizer comprises EDTA, Hepes, sodium sulfite and sodium caprylate. According to the diluent, a coronavirus quality control product has better stability after being diluted by adopting the diluent under the conditions of different dilution concentrations, storage temperatures after dilution, storage time and repeated freezing and thawing after cryopreservation, so the application range of the storage temperatures and the storage time of the liquid quality control product is favorably improved, and the influence on the accuracy of a test result and the issuing time of a report due to an abnormal indoor quality control result in actual operation is avoided. 本发明涉及一种冠状病毒质控品稀释液及其制备方法和应用，涉及检
