Development, Validation, and Implementation of an Augmented Multiwell, Multitarget Quantitative PCR for the Analysis of Human Papillomavirus Genotyping through Software Automation, Data Science, and Artificial Intelligence

Abstract

The value of HPV testing for cervical cancer screening is well established, where its use as primary screening option or as reflex test after atypical cytology results has recently gained wide acceptance. The importance of full genotyping and viral load determination has been demonstrated to enhance the clinical understanding of the viral infection progression during follow-up or after treatment, thereby providing clinicians with supplementary tools for optimized patient management.In this study a new analysis method for the RIATOL quantitative PCR assay was developed, validated and implemented in the laboratory of clinical molecular pathology at A.M.L. (Sonic Healthcare, Belgium), under national accreditation and following the international ISO guidelines. It presents the successful validation of a high throughput, multi-target HPV analysis method, with enhanced accuracy on both qualitative and quantitative end-results. This is achieved by software standardization and automation of PCR curve analysis and interpretation, using data science and artificial intelligence (DS/AI). Moreover, the user-centric functionality of the platform was demonstrated to enhance both staff training and routine analysis workflows, thereby saving time and laboratory personnel resources.Overall, the integration of the FastFinder plugin semi-automatic analysis algorithm with the RIATOL qPCR assay proved to be a remarkable advancement in high throughput HPV quantification, with demonstrated capability to provide highly accurate clinical-grade results and to reduce manual variability and analysis time.
