  • Components influencing QA/QCFacilitiesAdministrationStandard Operating ProceduresPersonnel

  • Facilities and equipmentAdequate spaceseparation between incompatible activitiescondition of floors, walls, ceiling & benchesadequate storage spaceavailability of all necessary equipment and functioning properlyair qualitylogs maintained

  • Sample historySample bottlesSample transportationHolding timeHandling & storage in the lab

  • Media quality controlAll SOPs available for preparation of various mediaControl stock cultures maintained with logs+ve and -ve cultures used to ensure that media are functioning properlynon-selective medium used to evaluate selective mediaall media and reagents properly labeled and stored

  • Faecal coliforms on selective and non-selective media

  • Method quality controlMethod used is current, authorized and validatedMethod blanks to monitor contaminationDuplicate analysis performed to monitor precision within a runParallel analyses to monitor inter-technician method precisionConfirmation of organisms done routinely

  • PersonnelAdministrationLab staff qualificationsContinued education and monitoring of competencyGood lab practicesStandard operating procedures

  • Responsibilities of an AssessorTo apply the standardUnbiasedNot to judge the labProvide a comprehensive report based on assessment against the standard

  • Assessment TeamSelection of the assessment teamNot a pass/fail approachExplain the process to the lab being assessedCreate an informal atmosphere and an open approach

  • Assessment processTour of the facilitiesTrace of testsAssessment of the quality systemAssessment of the methodsStage meetingsReporting all the findings
