CASE NARRATIVE SUMMARY
All reported results are within defined laboratory quality control objectives unless listed below or otherwise qualified in this report.
[TOC_1]Case Narrative[TOC]
SM21-23 6200B
Qualifications:
Laboratory fortified blank/laboratory control sample recovery and duplicate recoveries outside of control limits. Data validation is not
affected since all results are "not detected" for associated samples in this batch and bias is on the high side.
Analyte & Samples(s) Qualified:

*QC result is outside of established limits.
Wide recovery limits established for difficult compound.
Wide RPD limits established for difficult compound.
#Data exceeded client recommended or regulatory level
Percent recoveries and relative percent differences (RPDs) are determined by the software using values in the
calculation which have not been rounded.
No results have been blank subtracted unless specified in the case narrative section.
FLAG/QUALIFIER SUMMARY
Detected but below the Reporting Limit (lowest calibration standard); therefore, result is an estimated
concentration (CLP J-Flag).
J
Laboratory fortified blank/laboratory control sample recovery and duplicate recoveries outside of control limits.
Data validation is not affected since all results are "not detected" for associated samples in this batch and bias is
on the high side.
L-02
Laboratory fortified blank/laboratory control sample recovery and duplicate recovery are outside of control limits.
Reported value for this compound is likely to be biased on the low side.
