In clinical practice, HMB is defined as excessive menstrual loss, which interferes with a woman’s physical, social, emotional, and/or material quality of life. In terms of blood loss, HMB is defined as a menstrual blood loss of >80 mL per period. This objective assessment can only be obtained by laborious, expensive, and inconvenient measurements involving collection of used sanitary protections. Therefore, simple indirect methods, such as detailed menstrual history or the use of PBAC are used to provide a semiquantitative assessment of the blood loss and its severity as well as monitoring response to treatment.
