| Povzetek: | BACKGROUND: Nucleic acid amplification tests (NAATs) assist in the diagnosis of numerous infectious diseases. They are typically sensitive and specific and can be quickly developed and adapted. Far more challenging is the development of standards to ensure NAATs are performing within specification; reference materials take time to develop and suitable reference measurement procedures (RMPs) have not been available. This study investigated digital PCR (dPCR) RMP delivery of traceability for NAAT external quality assessment (EQA). METHODS: Three National Metrology Institutes (NMIs) applied reverse transcription (RT)-dPCR as a candidate RMP to estimate the RNA quantity in 32 independent severe acute respiratory syndrome coronavirus 2 materials. The results were combined to value assign the respective materials: 21 materials were used in 6 rounds of EQA over 17 months for 61 laboratories for COVID-19 testing results compared with reference values. RESULTS: The agreement between the 3 NMIs showed <2-fold difference between laboratories. EQA laboratory reverse transcription quantitative PCR (RTqPCR) values estimation of viral RNA quantity showed good median agreement with RT-dPCR reference value; however, RT-qPCR differences were generally between 10- and 50-fold between laboratories. CONCLUSION: This work demonstrates how RT-dPCR can provide reference values for whole virus materials for NAAT quality assurance. RT-dPCR values guided EQA control material selection and provided EQA participants with traceability to RNA copy number delivered through the RMP. This approach can be used to support routine reference material use as well as to standardize quality assurance for NAATs where established reference materials are not available, such as in disease outbreaks. |
