Representative examples illustrate pronounced differences in the stability of distinct lipid species in whole blood. (A) LPC O-18:1 is an unstable and (B) Cer 18:1/24:0 is a very stable lipid species. Time points up to 1.5 h, n = 27 individuals; time points 2 h, 4 h, and 24 h, n = 56 subjects (at time point 2 h (30°C), one sample is missing). LPC 19:0 for LPC O-18:1 and Cer d18:1/17:0 for Cer 18:1/24:0 from the internal standards (IS) mixture were used for normalization. ∗P < 0.05. Cer, ceramide; LPC, lysophosphatidylcholine.
