Interest in vitamin D grew especially in the first decade of the 21st century when its role in the pathogenesis of various diseases was first mentioned. At that time, a demand for laboratory measurements of 25-hydroxyvitamin D that is used to assess the vitamin D body stores rose sharply, so most clinical laboratories had to abandon laborious manual methods and had to introduce various automated techniques. Due to different methodologies, the inter-laboratory variability of measurements increased, which led to inconsistent conclusions in studies and meta-analyses in this research field. The Vitamin D Standardization Program has been established in recent years. The main goal is to reduce the variability of measurements and to promote comparisons of individual laboratories’ measurements to the reference method</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:doc-AA5YE0SH"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:doc-AA5YE0SH" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:doc-AA5YE0SH/2c659527-06ca-4122-9e1e-96e90774a51f/PDF" /><edm:rights rdf:resource="http://rightsstatements.org/vocab/InC/1.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:intermediateProvider xml:lang="en">National and University Library of Slovenia</edm:intermediateProvider><edm:dataProvider xml:lang="sl">Slovensko farmacevtsko društvo</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:doc-AA5YE0SH/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:doc-AA5YE0SH" /></ore:Aggregation></rdf:RDF>
