摘要月经过多（heavy menstrual bleeding，HMB）是妇科门诊女性患者就诊最常见的原因之一，对女性生活质量、工作效率、医疗成本产生重大影响。女性对自身月经失血量（menstrual blood loss，MBL）的认知是诊断和治疗HMB的关键决定因素。自从50多年前报道的碱性血红素法以来，许多新的月经血量测量方法逐渐被开发和改进。然而，随着HMB观念的更新，对MBL的评价尚缺乏公认有效的方法。本文检索国内外月经血量评估的相关研究，对月经血量评估方法进行综述，希望通过总结不同方法的实用性和局限性，为临床决策和实验研究中的应用提供新的思路。

abstractsHeavy menstrual bleeding (HMB) is one of the most common reasons for women to visit gynecological clinics, which affects women's quality of life, work efficiency, and medical costs. Women's perception of menstrual blood loss (MBL) is a key determinant in the diagnosis and treatment of HMB. Since the publication over 50 years ago of the alkaline hematin method for quantifying MBL, many new methods have been developed and improved. However, with the updating of HMB concept, there is still no recognized effective method to evaluate MBL. This paper reviewed the methods of menstrual blood volume assessment, summarized the practicability and limitations of different methods, to provide new ideas for clinical decision-making and application in experimental research.
