Standard Reference Material 968e Fat-Soluble Vitamins, Carotenoids, and Cholesterol in Human Serum provides certified values
for total retinol, γ- and α-tocopherol, total lutein, total zeaxanthin, total β-cryptoxanthin, total β-carotene, 25-hydroxyvitamin
D3, and cholesterol. Reference and information values are also reported for nine additional compounds including total α-cryptoxanthin,
trans- and total lycopene, total α-carotene, trans-β-carotene, and coenzyme Q10. The certified values for the fat-soluble vitamins and carotenoids in SRM 968e were based on the agreement of results from
the means of two liquid chromatographic methods used at the National Institute of Standards and Technology (NIST) and from
the median of results of an interlaboratory comparison exercise among institutions that participate in the NIST Micronutrients
Measurement Quality Assurance Program. The assigned values for cholesterol and 25-hydroxyvitamin D3 in the SRM are the means of results obtained using the NIST reference method based upon gas chromatography-isotope dilution
mass spectrometry and liquid chromatography-isotope dilution tandem mass spectrometry, respectively. SRM 968e is currently
one of two available health-related NIST reference materials with concentration values assigned for selected fat-soluble vitamins,
carotenoids, and cholesterol in human serum matrix. This SRM is used extensively by laboratories worldwide primarily to validate
methods for determining these analytes in human serum and plasma and for assigning values to in-house control materials. The
value assignment of the analytes in this SRM will help support measurement accuracy and traceability for laboratories performing
health-related measurements in the clinical and nutritional communities. 相似文献
