Omega-3 blood biomarkers in dried blood spot samples after storage for 8 weeks in either a test tube, test tube under nitrogen, vacuum sealed bag or nitrogen dried in vacuum sealed bag. PUFA, polyunsaturated fatty acid; HUFA, highly unsaturated fatty acid; EPA, eicosapentaenoic acid; DHA, docosahexaenoic acid; DPAn-3, omega-3 docosapentaenoic acid; n-3, omega-3; n-6, omega-6; TT, test tube storage; NTT, test tube storage after nitrogen purging; VS, vacuum sealing in polypropylene bag; NVS, vacuum sealing in polypropylene bag after nitrogen purging. Bars represent means with error bars representing the S.D., n = 3. Bars with different letters within a storage condition are significantly different by Tukey’s HSD post hoc procedure (P < 0.05) after a significant F-value by one-way ANOVA (P < 0.05).
