Office of Dietary Supplements VDSP Commutability Study 2

SUMMARY: 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].

DATES: The expected start date for the study is June 2015.

ADDRESSES: For more information about the study and to let us know if 
you are interested in participating, please contact us at: 
[email protected].

FOR FURTHER INFORMATION CONTACT: Drs. Johanna Camara, NIST, and 
Christopher Sempos, ODS, Director and Co-Director, respectively, for 
the VDSP Commutability Study 2. Email: [email protected].

SUPPLEMENTARY INFORMATION: 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[supreg] (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.
    For details about the study design and time lines, see the recently 
published paper in the February 2015 edition of Clinical Laboratory 
News, (https://www.aacc.org/publications/cln/articles/2015/february/vitamin-d-commutability-study).

Deputy Director, National Institutes of Health.
