NIH Office of Dietary Supplements (ODS) and the National Institute of Standards and Technology (NIST), in collaboration with the College of American Pathologists (CAP) and Vitamin D External Quality Assessment Scheme (DEQAS), announce that as part of the Vitamin D Standardization Program (VDSP), they are recruiting laboratories to participate in a study of the commutability of pooled serum samples used in assays to measure total 25-hydroxyvitamin D [25(OH)D].
The expected start date for the study is June 2015.
For more information about the study and to let us know if you are interested in participating, please contact us at: firstname.lastname@example.org.Start Further Info

The objective of the study is to promote the standardized measurement of total 25(OH)D by evaluating the commutability of NIST Standard Reference Materials® (SRM) used as “trueness” controls and the materials used in the major Performance Testing/External Quality (PT/EQA) programs administered by CAP and DEQAS. Who Can Participate: (1) All commercial manufacturers of 25(OH)D assays (requests from manufacturers with assays in development will be considered); (2) Clinical and research laboratories using a commercial assay platform; (3) Laboratories for national/subnational nutrition surveys; and (4) Laboratories using in-house developed assays.
