Sample Types Tested & Validated Assays

Sample Types Tested

R&D Systems Biomarker Testing Service most often performs analysis using sample types that are typically evaluated during development of the R&D Systems assays. These include:

  • Serum
  • Plasma
  • Cell culture supernates
  • Cell lysates
  • Urine
  • Human breast milk
  • Human saliva
  • Other (custom evaluation available for unique sample types)

If a desired assay has not been validated for your sample type, custom sample-type evaluation is available by Biomarker Testing Service. Typical sample type evaluation includes:

  • Spike and recovery to identify matrix interference
  • Linearity of sample dilution
  • Inter-assay precision & reproducibility (between different plates)
  • Intra-assay precision & reproducibility (within a plate)

Sample type evaluations confirm that a particular assay is suitable for the sample type in question. Our Biomarker Testing Service team will also perform assays using kits that are not manufactured by R&D Systems.
