摘要 目的探讨串联质谱技术在新生儿遗传代谢病筛查和诊断中的作用和意义,统计并了解我市新生儿遗传代谢病发病率。方法收集2016年3月~2018年12月余姚市出生的新生儿足跟血干血滤纸片,通过串联质谱技术检测样本中氨基酸及酰基肉碱等指标,以筛查氨基酸、有机酸和脂肪酸代谢病共26种遗传代谢病,可疑阳性者进一步确诊。结果共筛查21 024例新生儿,可疑阳性769例,确诊8例,包括苯丙酮尿症4例,甲基丙二酸血症1例,瓜氨酸血症Ⅰ型1例,原发性肉碱缺乏症2例。结论应用串联质谱技术极大地推动了新生儿遗传代谢病筛查的发展,实现了新生儿遗传代谢病早发现早治疗的目的,从而避免患儿发生不可逆性的生长及智能发育障碍,提高人口素质。
