Direct measurement of menstrual blood loss is the only reliable basis of the diagnosis 'menorrhagia'. We describe modifications of the alkaline hematin method for measuring menstrual blood loss (MBL) which improve the recovery rate from 89 to 98% and make the method more suitable for routine laboratory use. Using this modified method, 5 out of 21 patients (24%) complaining of menorrhagia and scheduled for hysterectomy had an MBL less than 80 ml, which is the upper level of normal MBL.
直接测量月经量是诊断“月经过多”的唯一可靠依据。我们描述了用于测量月经量（MBL）的碱性正铁血红素法的改进方法，该方法将回收率从89%提高到98%，并使该方法更适合常规实验室使用。使用这种改进方法，21例主诉月经过多并计划进行子宫切除术的患者中有5例（24%）的月经量少于80毫升，这是正常月经量的上限。
