The value for C18:2 trans fatty acid can be determined based upon the NIST certificate by subtracting the value for 'Total Trans C18:1 Fatty Acids' from the value for 'Total Trans C18:1 and C18:2 Fatty Acids'. The C18:3 trans fatty acids are not analyzed, as only α-Linolenic Acid is reported and is all-cis. Please note that there is also a value for 'Total Trans Fatty Acids'. Please see the link below to review the NIST Certificate:

General description
This SRM is intended primarily for validation of methods for determining proximates, fatty acids, cholesterol, vitamins, elements, amino acids, and nucleotides in infant and adult nutritional formulas and similar materials. This SRM can also be used for quality assurance when assigning values to in-house reference materials. The SRM is a hydrolyzed protein based, hybrid infant/adult nutritional powder prepared by a manufacturer of infant formula and adult nutritional products.A unit of SRM 1869 consists of ten packets, each containing approximately 10 g of material.Additional Notes: SRM 1869 is intended for research use, NOT FOR HUMAN CONSUMPTION. This material contains some nutrients at levels not permitted in infant formula and is NOT AN INFANT FORMULA. See Certificate of Analysis for storage and use instructions.
