Abstract In Standard Reference Material 968b, fat-soluble vitamins and cholesterol in human serum, certified values are provided for cholesterol, retinol, retinyl palmitate, α-tocopherol, trans-β-carotene, total β-carotene (trans plus cis isomers), total α-carotene, and lutein. Non-certified values are also reported for γ-tocopherol (includes β-tocopherol), δ-tocopherol, zeaxanthin, β-cryptoxanthin, trans-lycopene, trans-lycopene, trans-α-carotene, total lycopene, 9-cis-βcarotene, 13- plus 15-cis-β-carotene, and 15-cis-β-carotene. Both certified and non-certified values are based on the agreement among results from three different liquid chromatographic analytical procedures developed at NIST and from an interlaboratory comparison exercise among institutions that participate in a NIST-managed Micronutrients Measurement Quality Assurance Program. Cholesterol is certified in this material using the NIST isotope dilution/mass spectrometric definitive method.
