SRM 2378 Fatty Acids in Human Serum

Donor serum for SRM 2378 was collected from three groups of individuals: (level 1) three healthy donors who took 1000 mg/day of fish oil supplements for a minimum of one month prior to collection; (level 2) three healthy donors who took 1000 mg/day of flaxseed oil supplements for a minimum of one month prior to collection; and (level 3) three healthy donors who did not take either fish or flaxseed oil supplements for one month prior to collection.  Value assignment of the mass fractions of the fatty acids in SRM 2378 was based on the results of one or two analytical methods at NIST and one analytical method at the Centers for Disease Control (CDC) with confirmation by data provided by an interlaboratory comparison. This data is public in the Certificate of Analysis for this material.
