Study summary

The purpose of this study is to validate a patient self-sampling vaginal collection kit and laboratory testing for the detection of HPV (human papillomavirus) infection. Researchers will compare the laboratory results of self-collected vaginal swab samples to usual healthcare provider-collected cervical swab samples to determine the laboratory HPV testing accuracy of the self-collection swab.

  • Excluded if self-reported as currently menstruating, pregnant, or within 3 months following pregnancy.
  • Excluded if no cervix (history of total hysterectomy).
  • Excluded if moderate to heavy vaginal bleeding on the day of the visit.
  • Excluded if reason for visit in Gynecology Clinic is abnormal vaginal discharge.
  • Exclude patients who are on Gynecology Colposcopy Clinic for LEEP (loop electrosurgical excision procedure).

What researchers measure

Primary outcomes

  1. Concordance of Patient-collected and Clinician-collected Samples to Detect HPV Infection

    Patient-collected vaginal swab HPV results compared with gold standard of clinician-collected cervical swab) to accurately detect HPV infection

    Time frame: Baseline (sample was collected up to 21 days form the date of registration)

Secondary outcomes

  1. Patient-reported Acceptability of Using the Evalyn Brush

    Assessed by survey question "Overall, how acceptable was it for you to collect the sample using the Evalyn® brush?," which was answered on a 4-point scale (completely unacceptable, unacceptable, acceptable, or completely acceptable).

    Time frame: Baseline (sample was collected up to 21 days form the date of registration)
