摘要液相串联质谱技术具有高灵敏度、高特异性、高通量等特点，可以准确、高效的检测维生素、胆汁酸、类固醇激素、代谢小分子等人体内水平的变化。液相串联质谱技术作为预防医学中筛查、诊断疾病的一种有效手段，在妇幼健康方面广泛应用，有效降低妇幼疾病的发生率，提高我国妇幼人群的健康水平。目前质谱技术在我国面临着许多挑战，但同时也有诸多机遇。本文将阐述液相串联质谱技术在妇幼健康领域的代表性应用方向，并讨论临床实验室开展质谱检测遇到的主要一些问题。

abstractsDue to its ultra-high sensitivity, specificity and throughput, liquid chromatography tandem mass spectrometry (LC-MS/MS) has become an important analytical tool in clinical laboratories in quantifying various small molecules, such as vitamins, bile acids, steroids and other internal metabolites relevant to maternal diseases. As an effective means of screening and diagnosing diseases in preventive medicine, LC-MS/MS has been widely used in maternal and child health, contributing to the reduction of the incidence of maternal and child diseases and premature morbidity and mortality. At present, LC-MS/MS is an emerging and powerful platform in laboratory testing in China, facing both challenges and opportunities. In this article, the representative applications in the field of maternal and child health are summarized and discussed, along with the major hurdles of LC-MS/MS in clinical recognition and implementation.
