Measurement of Urinary Hormones in Patients With Abnormal Uterine Bleeding to Study Uterine Cancer Progression (MIRA)

May 6, 2026 updated by: Aline Talhouk, University of British Columbia

Quantitative Hormonal Biomarkers of Uterine Cancer Progression in Patients With Abnormal Uterine Bleeding

The investigators will obtain urine hormone results and validated menstrual bleeding score from people experiencing abnormal uterine bleeding. The investigators will evaluate satisfaction and ease of use of Mira monitor. The investigators will measure recruitment rate, attrition and cycle collection completeness of data. The investigators will evaluate menstrual health literacy at baseline and at the conclusion of the study.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Urinary Hormone Levels (Mira Monitor)
Time Frame: 3 months
Daily urinary hormone levels, including follicle-stimulating hormone (FSH), estrone-3-glucuronide (E3G), luteinizing hormone (LH), and pregnanediol glucuronide (PdG), will be measured using the Mira monitor. Participants will collect first morning urine samples and manually enter results into MyCap. Unit of Measure: Hormone concentration (as reported by Mira; e.g., mIU/mL or µg/mL).
3 months
Menstrual Bleeding Severity
Time Frame: 3 months
Menstrual bleeding will be self-reported daily in MyCap using a modified Mansfield-Voda-Jorgensen (MVJ) Menstrual Bleeding Scale (0-6). Higher scores indicate heavier menstrual bleeding.
3 months
Acceptability and Feasibility of Mira Monitor
Time Frame: 3 months
Acceptability and feasibility will be assessed using a study-specific questionnaire administered via MyCap at study completion. Questionnaire response scores (ordinal Likert-scale responses; e.g., 1-5 per item). Higher scores indicate greater acceptability, ease of use, and perceived usefulness.
3 months
