Abstract

The use of meconium as a drug-screening matrix for newborns has been the gold standard of care for the past two decades. A recent study using matched pairs of meconium and umbilical cord demonstrated a high degree of agreement. The use of liquid chromatography-tandem mass spectrometry as a means to confirm amphetamines presumptive positive umbilical cord specimens for amphetamine and methamphetamine is described here for the first time. The limit of detection for both compounds was 0.2 ng/g. The limit of quantitation for both compounds was 0.6 ng/g. The assay was linear for both compounds up to 100 ng/g.

摘要

在过去二十年里,使用胎粪作为新生儿药物筛查基质一直是护理的金标准。最近一项使用配对胎粪和脐带样本的研究显示出高度一致性。本文首次描述了使用液相色谱 - 串联质谱法来确认脐带样本中苯丙胺和甲基苯丙胺疑似阳性的情况。两种化合物的检测限均为0.2 ng/g。两种化合物的定量限均为0.6 ng/g。该检测方法对两种化合物在高达100 ng/g的范围内呈线性。
