FREE THYROXINE AND FREE TRIIODOTHYRONINE ANALYSIS BY MASS SPECTROMETRY

摘要

Methods, systems and kits for the simultaneous or sequential analysis of oneor more hormones by mass spectrometry are disclosed. The methods requireminimal sample size and minimal preparation time. The methods compriseionizing the hormones and analyzing the hormones by mass spectrometry. Inaddition, methods, systems and kits for the simultaneous or sequentialanalysis of free thyroxine (FT4) hormone and free-triiodothyronine (FT3) isdisclosed comprising ionization of the (FT4) and (FT3) hormone in the negativemode using an electrospray source.
