Laboratory procedures
  • Handle all samples as if potentially infectious, using safe laboratory procedures. As the sensitivity and titer of potential pathogens in the sample material varies, the operator must optimize pathogen inactivation by the Lysis / Binding Buffer or take appropriate measures, according to local safety regulations.
  • Do not eat, drink or smoke in the laboratory work area.
  • Do not pipette by mouth.
  • Wear protective disposable gloves, laboratory coats and eye protection, when handling samples and kit reagents.
  • Wash hands thoroughly after handling samples and reagents.
Waste handling
  • Discard unused reagents and waste in accordance with country, federal, state, and local regulations.
  • Safety Data Sheets (SDS) are available online on dialog.roche.com, or upon request from the local Roche office.
