[Federal Register Volume 80, Number 62 (Wednesday, April 1, 2015)] [Notices] [Page 17441] From the Federal Register Online via the Government Publishing Office [www.gpo.gov] [FR Doc No: 2015-07326] ----------------------------------------------------------------------- DEPARTMENT OF HEALTH AND HUMAN SERVICES National Institutes of Health 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: vdsp@mail.nih.gov. FOR FURTHER INFORMATION CONTACT: Drs. Johanna Camara, NIST, and Christopher Sempos, ODS, Director and Co-Director, respectively, for the VDSP Commutability Study 2. Email: VDSP@mail.nih.gov. 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). Dated: March 24, 2015. Lawrence A. Tabak, Deputy Director, National Institutes of Health. [FR Doc. 2015-07326 Filed 3-31-15; 8:45 am] BILLING CODE 4140-01-P
