Quantitative profiling of biomarkers related to B-vitamin status, tryptophan metabolism and inflammation in human plasma by liquid chromatography/tandem mass spectrometry

Plasma tHcy was inversely related to all B vitamins, and the tHcy–B vitamin relationships were modified by the MTHFR poly- morphism and were strongest in subjects with the TT

We investigated the stability of 32 biomarkers related to one-carbon metabolism and B vitamin function in serum and plasma (EDTA, heparin, and citrate) stored at room

tandem mass spectrometry methods for quantitation of mevalonic acid in human plasma and urine: method validation, demonstra- tion of using a surrogate analyte, and demonstration

Our study extends these observations and shows that the chronic administration of oral PN produces steady-state concen- trations of the B 6 vitamers after 3 days and that
