Traceability
This method has been standardized against a primary reference material (NERL).

Precision
Representative performance data on Cedex Bio Analyzers are shown. Results obtained in individual laboratories may differ.
Precision was determined in samples of three concentration levels. Coefficients of variation (CV) were calculated for in-run precision (n=21) and inter-run precision (on 10 days).

• Handle all samples as if potentially infectious, using safe laboratory procedures. As the sensitivity and titer of potential pathogens in the sample material can vary, the operator must optimize pathogen inactivation and follow the 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.

• Discard unused reagents and waste in accordance with country, federal, state, and local regulations.
• Safety Data Sheets (SDS) are available online at documentation.roche.com, or upon request from the local Roche office.
