Study Title | A Sentinel Serum Quality Management Program for NMR Metabolomics |
Study Type | Pharmacometabolomics |
Study Summary | Pooled human serum (Sentinel Serum Samples) was aliquoted for storage at -80C and subsequently had NMR spectra acquired annually for three years. This was to determine sentinel serum sample utility for a quality management program to monitor NMR reproducibility. Sentinel serum quality control samples allowed the quantification of variance between different profilers within a project. They also demonstrated declines in metabolite concentrations over time. A sentinel program is useful for tracking changes in QC serum samples from long-term storage. Separately, QC samples show negligible variance introduced by multiple profilers of NMR spectra within a project. |
