Q

What is the current biomedical standard for measuring blood loss during menstruation?

A

Alkaline hematin method, which is quite expensive and can be inconvenient for women. It requires a woman to collect all menstrual products (pads, tampons) used during a menses and bring them to a lab, where these materials are then tested to determine how much blood they contain, enabling a calculation of the amount of blood lost during the menses. The products are treated with sodium hydroxide for 48 hours to convert the menstrual blood hemoglobin to alkaline hematin and then the optical density of the alkaline hematin is measured spectrophotometrically. Next, venous blood is drawn from the woman and the optical density of the alkaline hematin in that peripheral blood is measured. The ratio of the hemoglobin concentration in the total menstrual discharge to the peripheral blood is considered the volume of menstrual blood loss.

Though these drugs are expensive and have many side effects, they can be helpful in stemming bleeding while waiting for surgery. Short-term use only.
