EFFECTIVE ^ATE PAGE <br />HC-QAC-02 0 1 /06/92 90 of 104 <br />If the requirements listed above were not met, document all corrective actions <br />' taken and contact the client, if necessary. <br />14.6 Data Modification, Updates, And Traceability <br />Analysts are required to record all raw laboratory data in the laboratory <br />notebook (including initial analytical runs, reanalysis, dilutions, etc.). When <br />errors are detected, initial and date all error corrections, data modifications, <br />and data updates on the raw laboratory data. It is advisabNe to record the <br />LIMS assigned QA number on all raw laboratory data. This QA number is <br />used to reference both the analytical and associated quality assurance data <br />in L1MS. <br />During final report preparation, reporting personnel shall print the LIMS- <br />generated analytical and quality assurance reports to document the data <br />which was entered by the analysts. The following procedure is used by <br />reporting personnel to document data modifications and updates. <br />' • Clearly mark or highlight any errors which are detected during the data <br />review process. <br />• Verify all questionable data with the analyst before changing data in LIMS. <br />A review of the raw laboratory data (see section 14.1) may be required to <br />confirm necessary changes. <br />• Initial and date all data modifications on the original LIWIS generated <br />analytical and quality assurance reports. <br />' The original reports containing data "as entered" and all highlighted <br />modifications must be kept in the job file to provide an accurate record of <br />all changes which have been made. <br />14.7 Corrective Action Process <br />When non-conformances occur, analysts must immediately inform the <br />appropriate laboratory section supervisor. The laboratory section supervisor <br />' will then determine what corrective action is required. The following <br />guidelines are used to validate data and determine what, if any, corrective <br />action is necessary. <br />
