Abstract Pseudoviruses containing E6/E7 RNA sequences of HPV16 and HPV18 were selected as reference materials. One-step reverse transcription digital PCR method was used to quantify content of E6/E7 RNA. HPV16 and HPV18 (E6/E7) RNA pseudoviruses were prepared and certificated (NIM-RM5231 and NIM-RM5232), which showed good uniformity and stability. The reference values with expanded uncertainty of the two reference materials were: (9.7±1.8)×102copies/μL, (5.9±1.1)×102copies/μL. The values were verified by multiple laboratories, and the relative standard deviations of the determination results were all less than 10%. The reference materials can provide reference for the quality control of the related detection of high-risk HPV E6/E7 RNA.
