Additional file 13. Table S9. Summary of repeatabilityfor labeled standard analytes across all extraction methods and LC-MS analyses. The table displays a mean relative standard deviationfor plasma vs. serum in each LC-MS conditions . Empty boxes stands not detected.MeOH : methanol; MeOH:ACN : methanol combined with acetonitrile; ACN: acetonitrile; SPE : solid preparation extraction; ESI : electrospray ionisation; RP: reverse phase.
