BILLING CODE 4140-01-P DEPARTMENT OF HEALTH AND HUMAN SERVICES National Institutes of Health Notice of Vitamin D Standardization Program

(VDSP)Symposium: Tools To Improve Laboratory Measurement SUMMARY: The National Institutes of Health, Office of Dietary Supplements (ODS), and the National Institute of Standards and Technology (NIST), are sponsoring a one-day symposium on November 14, 2013, to present information about the Vitamin D Standardization Program

(VDSP)to those with an interest in the effort to standardize vitamin D measurement. These groups include commercial assay manufacturers; commercial, clinical, and research laboratory personnel; vitamin D researchers; and members of professional societies with clinical and public health interest in vitamin D. DATES: November 14, 2013, 8:30 a.m. to 5:30 p.m. (Eastern Time). ADDRESSES: NIST, 100 Bureau Drive, Green Auditorium, Gaithersburg, MD 20899-1070. The NIST campus is a highly secured area. Because of this, you are required to register in advance and must present a current government-issued identification card with photo when entering the facility. The Web address for registration is *https://events-support.com/events/VDSP_Symposium_2013* . FOR FURTHER INFORMATION CONTACT: Ms. Cindy Rooney, ODS, National Institutes of Health, 6100 Executive Boulevard, Room 3B01, Bethesda, MD 20892-7523; email: *rooneyc@mail.nih.gov* . SUPPLEMENTARY INFORMATION: The ODS established the VDSP in November 2010 in an effort to standardize the laboratory measurement of vitamin D status worldwide. Standardization is essential to improve the detection, evaluation, and treatment of vitamin D deficiency and insufficiency by making measurements of serum total 25-hydroxyvitamin D [25(OH)D] accurate and comparable over time, location, and laboratory procedure. The symposium on November 14 will

(1)Describe the VDSP;

(2)present data from the VDSP inter-laboratory comparison and commutability studies demonstrating its effectiveness;

(3)demonstrate how tools developed through the VDSP can be used to improve the standardization of vitamin D measurement in the United States and around the world; and

(4)solicit feedback from symposium participants on how the VDSP can be improved to meet the needs of participants. All participants must register at *https://events-support.com/events/VDSP_Symposium_2013* . Dated: October 21, 2013. Lawrence A. Tabak, Deputy Director, NIH.
