Do QIAsymphony Virus/Bacteria samples require pretreatment before they are loaded onto the instrument?
FAQ ID -2039

Pre-treatment of samples used with the QIAsymphony Virus/Bacteria Kits can improve nucleic acid extraction for some sample types. Viscous samples (e.g., sputum, respiratory aspirates) might require liquefaction to enable pipetting. Pretreatment protocols are provided in the QIAsymphony Virus/Bacteria Handbook.
