The present study assessed serum 25(OH)D in a cohort of 74235 outpatients by liquid-chromatography-tandem-mass-spectrometry (LC-MS/MS).
The investigators studied the distribution of serum 25(OH)D concentrations in males and females of different age groups, the prevalence of measurable amounts of 25(OH)D2 and seasonal variability.

Detailed Description:
Measurements were performed under routine circumstances. Samples were collected in serum tubes with clot-activator.
