RNA nucleic acid constant value control material and preparation method thereof

The invention aims at providing an RNA nucleic acid constant value control material with accurate target value constant value, good excellent traceability, stability and uniformity and high use valueto meet scientific research and clinical use. The material consists of a clinical positive plasma (serum) sample or a virus culture and RNA protective agent diluents. A target value is determined withthe material traced to an international standard material, and nucleic acid quantitative detection kits from 3-5 different manufacturers widely used in the market and excellent in reagent performanceare adopted for detection. By means of the material and the method, the state of reagents and instruments in clinical examination and the personnel operation can be effectively monitored. The material can be stored for more than one year in the environment of (-20+-5) DEG C and stabilized for more than 3 months at the temperature of 2-8 DEG C. The method has the advantages of stable measured value, good evenness, accurate
