It may sound surprising, but yes—your period can help detect a virus hiding in your uterus. During your menstrual cycle, your body naturally sheds the endometrial lining, which is made of the same cells doctors sample during an endometrial biopsy. These cells travel out of the uterus and into your menstrual fluid.
Because HHV-6A lives inside endometrial cells, those cells carry the clues needed to find it. This means a period sample can show whether the virus is active in your uterus—without needing a painful biopsy or a clinic visit.
Scientists have confirmed that menstrual fluid contains DNA, RNA, hormones, immune markers, and whole endometrial cells. A 2022 research report called menstrual blood a “powerful, untapped diagnostic sample” because it contains the same biological information as a tissue sample from the uterus.
This is why menstrual-fluid testing, like Covee, can detect HHV-6A in a simple, at-home way. Instead of trying to find the virus in the blood (where it usually doesn’t show up), Covee looks directly at the cells where the virus actually hides.
If a period sample can detect a virus inside the uterus, the next thing many women want to know is:
“Do other women actually benefit from this testing?”
