We Were Researching it!
A recent (August 2023) Scientific American Article points out that given the myriad of menstrual products on the market, their absorbency has largely been ignored.
In the article the point (in short) is that a specialist will base treatment options partially on the amount of blood lost but will ask "how many pads or tampons do you use in a day" as the marker of loss.
Without translating that back to a measurable quantity - there is no accuracy. Some pads hold 20ml and others 40ml (making the leeway for miscalculation is double).
I HAVE NEWS FOR SCIENTIFIC AMERICAN
CANFib has not only been preaching, but has produced (and provides) practical charting tools for Women with Fibroids that calculate blood loss based on particular menstrual products and the volume they hold (offering a more accurate view for their specialist).
By offering accurate symptom information, a patient can start treatment at the most logical stage for her condition rather than at the beginning of the recommended list.
