NCT03388203
Brief Summary:
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. As per routine procedure, samples were centrifuged upon arrival in the lab and stored at 4° C until measurement. 25(OH)D3 and 25(OH)D2 were quantitated separately. Results from subjects \<18 years were excluded from the analysis. The study was approved by the local Ethics Committee.
