Evaluation of the clinical performance of the Daye Diagnostic Tampon (DDT) for the detection of Human Papilloma Virus (HPV) infection associated with high grade cervical disease. Cross sectional design with comparison to a clinician taken biospecimen. Performance will be measured relative to the presence/absence of histologically confirmed disease
Type of Study: Clinical Trial
Goal: The goal of this clinical trial is to evaluate the clinical performance of the Daye Diagnostic Tampon (DDT) for the detection of HPV infection associated with high-grade cervical disease.
Main Questions:
What is the sensitivity and specificity of molecular HPV assays in detecting high-grade cervical disease (CIN2+) using the DDT compared to a clinician-taken, liquid-based cytology (LBC) sample?
How does the relative sensitivity and specificity of HPV detection in the tampon compare to the LBC sample for the detection of CIN2+?
Participants:
Women attending routine colposcopy clinics as part of standard care.
Main Tasks:
Provide informed consent. Undergo routine colposcopy. Use the DAYE Diagnostic Tampon (DDT). Provide a clinician-taken liquid-based cytology (LBC) sample. Complete a short questionnaire.
Comparison Group:
Researchers will compare the performance of the DAYE Diagnostic Tampon (DDT) to a clinician-taken, liquid-based cytology (LBC) sample to determine if there are differences in sensitivity and specificity for the detection of high-grade cervical disease (CIN2+). The comparison will assess the relative sensitivity and specificity of HPV detection in the tampon versus the LBC sample for the presence/absence of histologically confirmed disease.

| Daye Diagnostic Tampon | Device | The DAYE Diagnostic Tampon is a class A in vitro diagnostic device. It has CE certification (self-certified via a declaration of conformity, following the IVDR (EU) 2017/746). The DDT is constructed entirely from woven cotton and consists of an absorbent core wrapped in a protective sleeve. The DDT is loaded in an applicator to aid with insertion. The DDT needs to be worn for 20 minutes then when removed should be placed immediately in the sterile container. |

| Sensitivity and specificity (%) of the tampon-assay combination & LBC assay combination for detection of histologically high grade disease | To assess the sensitivity and specificity of molecular HPV assays for the detection of high grade cervical disease (defined as cervical intraepithelial neoplasia grade 2 or worse, CIN2+) using the DDT AND a clinician taken, liquid based cytology (LBC) sample | end of study (12 months from start) |
| Relative sensitivity of the tampon-assay combination vs the LBC-assay combination | To determine the relative sensitivity and specificity of HPV detection in the tampon vs the LBC sample for the detection of CIN2+. | end of study (12 months from start) |
| Measure | Description | Time Frame |

Quantification of Participation Rates: A comparison between the number of colposcopy patients invited to participate and those who actively engaged in research. This study aims to determine the level of willingness within the colposcopy population to partake in research focused on the utilization of tampons for microbial testing. The outcome measure will specifically assess the percentage of invited participants who actively contribute to the study, shedding light on the feasibility and acceptance of the proposed research intervention within this demographic. This quantification will be instrumental in understanding the potential for successful recruitment and engagement in future studies involving tampon-based microbial testing. |
