Objective: This project aims to evaluate the effect of two isotopically labelled internal standards on the quantification of 17OHP by liquid chromatography-tandem mass spectrometry (LC-MS/MS) and gas chromatography-tandem mass spectrometry (GC-MS/MS) as an orthogonal technique.Methods: Three LC-MS/MS and one GC-MS/MS laboratories, spanning four countries worldwide, who routinely measure serum17OHP, compared two internal ...
