Abstract:
1. A method for determining the amount of reverse triiodothyronine (rT3) in a sample by tandem mass spectrometry, said method comprising: a. subjecting the rT3 from the sample to liquid chromatography; b. ionizing rT3 from the sample and an internal standard to generate at least one rT3 ion and at least one internal standard ion detectable by tandem mass spectrometry; c. determining the amount of said at least one rT3 ion and the amount of said at least one internal standard ion by tandem mass spectrometry; and d. determining the amount of rT3 in the sample, comprising comparing the amount of said at least one rT3 ion and the amount of said at least one internal standard ion.
