Publication: Simultaneous determination of 5-hydroxytryptophan and 3-O-methyldopa in dried blood spot by UPLC-MS/MS: A useful tool for the diagnosis of L-amino acid decarboxylase deficiency
This original study article, published in the Journal of Chromatography B, outlines a study to establish a reliable method to assess both 5-hydroxytryptophan (5-HTP) and 3-O-methyldopa (3-OMD) in dried blood spot (DBS) analysis through ultra-performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS) technology, for the biochemical diagnosis of AADC deficiency
Review the role of high-performance liquid chromatography (HPLC) analysis of cerebrospinal fluid (CSF) neurotransmitter metabolites in the diagnosis of AADC deficiency
Find out about a new tool for the detection of 5-HTP alongside 3-OMD in DBS for the diagnosis of AADC deficiency
Understand the mechanism behind simultaneous measurement of 5-HTP and 3-OMD in DBS and how this improves the specificity and sensitivity of the biochemical diagnosis of AADC deficiency is discussed
