Automated Assay for the Determination of Methylmalonic Acid, Total Homocysteine, and Related Amino Acids in Human Serum or Plasma by Means of Methylchloroformate Derivatization and Gas Chromatography–Mass Spectrometry
TL;DR: This assay combines a simple and automated sample preparation with selective and sensitive GC-MS analysis and is well suited for the combined measurement of MMA, tHcy, and the related amino acids.
Variability and determinants of total homocysteine concentrations in plasma in an elderly population
Robert Clarke,Peter Woodhouse,Arve Ulvik,Chris Frost,Paul Sherliker,Helga Refsum,Per Magne Ueland,Kay-Tee Khaw +7 more
TL;DR: The variability of plasma total homocysteine (tHcy) was examined in 96 individuals over a 1-yr period and epidemiological studies based on single tHcy measurements may underestimate the magnitude of any risk associations with disease by 10-15%.

Cobalamin Status and Its Biochemical Markers Methylmalonic Acid and Homocysteine in Different Age Groups from 4 Days to 19 Years
TL;DR: In infants 6 weeks to 6 months, concentrations of the metabolic markers MMA and tHcy were higher than in the other age groups and strongly correlated to cobalamin, whereas in older children, both makers showed correlations tocobalamin and folate concentrations documented in adults.

Choline and risk of neural tube defects in a folate-fortified population
Gary M. Shaw,Richard H. Finnell,Henk J. Blom,Suzan L. Carmichael,Stein Emil Vollset,Wei Yang,Per Magne Ueland +6 more
TL;DR: Findings for choline, for which low levels was a risk factor and higher levels were a protective factor for NTDs, may offer a useful clue toward understanding the complex etiologies of N TDs in an era of folic acid fortification of the food supply.

TL;DR: Bone mineral density was measured be-tween 1997 and 2000 in 2268 men and 3070 women,aged 47 to 50 and 71 to 75 years, from the HordalandHomocysteine Study cohort as mentioned in this paper.
