Abstract:
Contamination in a molecular laboratory may lead to erroneous results with potential to cause patient harm if not promptly identified and corrected. A general overview of the practices used in molecular laboratories to identify and address contamination once an event has occurred is discussed. The process used to assess the risk associated with the identified contamination event, determine the appropriate course of immediate action, perform a root cause analysis to determine the source of contamination, and assess and document the results of the decontamination process will be reviewed. Finally, the chapter will discuss a return to normal with consideration of appropriate corrective actions to mitigate future contamination events.
