Liquid Chromatography–Tandem Mass Spectrometry Analysis of Folate and Folate Catabolites in Human Serum

Simple method for the quantitative analysis of endogenous folate catabolites p-aminobenzoylglutamate (pABG) and its acet- amido (apABG) derivative in human serum and urine by

At baseline, tHcy in plasma and folate, total cholesterol, HDL-cholesterol, and creatinine in serum were signifi- cantly higher in patients with hypothyroidism than in patients

Greater concentrations of unmetabolized folic acid are associated with higher serum folate concentrations (7, 254), suggesting that the amount of folic acid in

Measurements of folate concentrations in 399 fresh serum samples from healthy blood donors obtained with the pABG method and with a microbiologic assay showed good agreement (Fig. 4,

13,14,22 In our study, differences in homocysteine concentration between the two ethnic groups were explained by lower serum B 12 and folate concentrations in Indian Asians,

Observational studies have demon- strated a positive correlation between maternal serum or red blood cell folate and infant birthweight or higher birth- weight in

Folate mea- sured as pABG equivalents is the most stable folate index in serum samples stored at both room temperature and as frozen specimens and the pABG assay may be the method

We found that dietary folate intake, supplemental folic acid use, and maternal plasma folate concentrations, measured in the second trimester, were not associated with gestational
