Study summary

The purpose of this study is to investigate the feasibility and efficacy of assessing HR-HPV DNA and HPV E6/E7 mRNA via self-collected menstrual blood in a smart menstrual pad. In other words, can the investigators detect the high risk strains of the human papilloma virus (HPV) that are associated with cervical cancer in self-collected menstrual blood, as an alternative to collecting vaginal swabs.

Groups and cohorts

  • High Risk HPV Positive Cohort

    This group of women have tested positive for HR-HPV at annual cervical cancer screening and have been invited to participate in the study. They will be asked to use a menstrual pad we provide that collects a sample of their menstrual blood (strip). The strip will be mailed back to us for analysis (Menstrual Blood Analysis). These women will also be asked to conduct a self-swab vaginally to be sent back to us for analysis. These women will return 6-months after their positive HR-HPV for standard of care testing. All results of the standard of care tests, menstrual blood tests, and self-swab tests will be compared.

    Diagnostic Test: Menstrual Blood Analysis (Menstrual Blood Analysis)

Interventions

  • Diagnostic testMenstrual Blood Analysis (Menstrual Blood Analysis)

    We will be testing women's menstrual blood to investigate the feasibility and efficacy of assessing HR-HPV DNA and HPV E6/E7 mRNA via self-collected menstrual blood from a menstrual pad.

What researchers measure

Primary outcomes

  1. Agreement Between Modified Menstrual Pad and Clinician-Collected Specimen

    The clinician collected a vaginal swab to detect HPV, then participants used a modified menstrual pad to self-collect a sample within 2 months of the clinician collected swab (may have happened at up to 4 mo.). Participants may have had prior history of dysplasia or HPV positivity, or were from general population receiving regular check-up. Agreement between the clinician-collected swabs and participant-collected menstrual samples was assessed in: * Participants who sent their sample to the lab within 2 months, and whose sample was analyzed for the presence of HPV * Participants enrolled at the time of a previously scheduled colposcopy, with a biopsy taken (if clinically appropriate) showing moderate-to-severe dysplasia (cervical intraepithelial neoplasia \[CIN\] 2 or worse) * Participants enrolled at the time of a previously scheduled colposcopy, with a biopsy taken showing moderate-to-severe dysplasia, and participants whose laboratory results indicated presence of high-risk HPV.

    Time frame: 2-4-months after initial clinician collected samples were obtained and sent for HR-HPV DNA or HPV E6/E7 mRNA

  2. Agreement Between Self-collected Vaginal Swabs vs Clinician-collected Cervical Specimens With High-risk HPV-Positive Results

    Time frame: 2-4-months after initial positive screen for HR-HPV DNA or HPV E6/E7 mRNA

Secondary outcomes

  1. Number of Participants Who Preferred the Modified Menstrual Pad to Clinician-collected Cervical Specimens

    Time frame: 2-4-months after initial positive screen for HR-HPV DNA or HPV E6/E7 mRNA

  2. Number of Participants Who Opted Out of Self-swab Due to Discomfort With the Procedure

    Time frame: 2-4-months after initial positive screen for HR-HPV DNA or HPV E6/E7 mRNA
