Development and clinical validation of an ERA-CRISPR/Cas12a assay for the rapid detection of 14 high-risk HPV types

High-risk human papillomavirus (HR-HPV) is the principal etiological agent of cervical cancer, and early detection remains central to effective disease prevention. Current PCR-based assays, however, rely on specialized laboratories and trained personnel, limiting their deployment in many settings. Here, we report a streamlined CRISPR-Cas12a assay that integrates direct sample lysis, ERA, and CRISPR-based detection into a single workflow operable with only a simple heating device to determine the presence of 14 HR-HPV types. The assay achieves high analytical sensitivity, strong specificity, and robust clinical performance while maintaining low cost and ease of use. This platform enables rapid HR-HPV detection and scalable screening, particularly in resource-constrained environments, with the potential to facilitate earlier intervention and reduce cervical cancer incidence.
