Harmonizing lipidomics: NIST interlaboratory comparison exercise for lipidomics using SRM 1950-Metabolites in Frozen Human Plasma

Abstract

As the lipidomics field continues to advance, self-evaluation within the community is critical. Here, we performed an interlaboratory comparison exercise for lipidomics using Standard Reference Material (SRM) 1950-Metabolites in Frozen Human Plasma, a commercially available reference material. The interlaboratory study comprised 31 diverse laboratories, with each laboratory using a different lipidomics workflow. A total of 1,527 unique lipids were measured across all laboratories and consensus location estimates and associated uncertainties were determined for 339 of these lipids measured at the sum composition level by five or more participating laboratories. These evaluated lipids detected in SRM 1950 serve as community-wide benchmarks for intra- and interlaboratory quality control and method validation. These analyses were performed using nonstandardized laboratory-independent workflows. The consensus locations were also compared with a previous examination of SRM 1950 by the LIPID MAPS consortium. While the central theme of the interlaboratory study was to provide values to help harmonize lipids, lipid mediators, and precursor measurements across the community, it was also initiated to stimulate a discussion regarding areas in need of improvement.

Figures

Fig. 1.
Fig. 1.
Lipid class composition of SRM 1950, according to number of lipid species (A) and concentration (B). Only lipid species that were measured by at least five participating laboratories are included in this figure (n = 339).
Fig. 2.
Fig. 2.
COD (in percent) for the MEDM lipids (n ≥ 5 laboratories reporting) organized by lipid class. Each point on the figure represents a single sum lipid composition. The COD was calculated by dividing the standard uncertainty by the final MEDM. CODs not shown in the figure are FC, eicosanoids, PGs, and PSs.
Fig. 3.
Fig. 3.
Sum of MEDM values for the most (in micromoles per milliliter plasma) (A) and least (in nanomoles per milliliter plasma) (B) concentrated lipid classes (EICO* in pmol/ml plasma) compared with the sum of concentrations provided by the LIPID MAPS consortium. The comparisons entail summing only the lipids measured in common between the compared data sets, with the total number of lipids fitting this criterion (per class and total) provided above each bar graph. Other PL represents the sum of PG and PS species. The error bars associated with the values standard uncertainties on the location estimates. Further information on this comparison, including total lipid concentrations, is included in the supplemental material (supplemental Table S17).
