General Tests/Methods Guidelines:

  • Sample container recommendation based on single sample collection, QC requirements not included
  • Samples should be kept cool at all times (4ºC)
  • Do not overfill preserved sample containers, chemical burns may result
  • For chain of custody form, please visit the Resources page
