Cytometry - Sample
Knowledge of the origin of the sample and awareness of the potential presence of pathogens (genetically modified or not) are keys for lab scientists' protection.
All unfixed materials (blood samples, various body fluids, cultured cells and environmental samples) should be a priori considered as biohazardous (the use of a fixative is not always sufficient to eliminate all type of biohazards);
The use of Class II biological safety cabinet for sample preparation is highly recommended;
Flow cytometer operators should be experienced and well trained;
in relation with the Biosafety status of the sample: appropriate containment level, protective equipment, work practices and waste management are adopted after a thorough risk assessment (according to the European Directive 2009/41/EC repealing Directive 90/219/EEC, European Directive 2000/54/EC).
