Menstrual blood is composed of three distinct body fluids:
- Whole blood
- Vaginal fluid
- Cells and fluid of the endometrial lining and the cervix
Your menstrual period blood includes capillary blood. We know it’s blood because we did the research of comparing venous blood (blood from your veins) to menstrual blood. Through clinical trials, Qvin proved that menstrual blood and venous blood correlate across the seven biomarkers initially tested.
Vaginal fluid and endometrial issue are also in menstrual blood. From Qvin research, HR-HPV can be detected using menstrual blood from the Q-Pad device and highly correlates with a clinician-collected Pap smear sampling. Research is needed but there is potential for using menstrual blood to non-invasively test for lipids, nutritional deficiencies, STIs, endometriosis, and cancer tumor markers.
