ATTACHMENT 1 BLIND PERFORMANCE TEST INVESTIGATION RESULTS
-- -----~--
e BLIND PERFORMANCE TEST INVESTIGATION RESULTS During a review of blind performance test results, a sample (Specimen No. 107-700-6464-0), which had screened "positive" for cocaine at our onsite testing facility at Surry Power Station, was identified by Company Employee Health Services personnel to have been tested by our Department of Health and Human Services (HHS) certified laboratory with negative results. We directed our HHS laboratory to perform a re-test of the specimen (Specimen No. 107-700-6464-1 ). The re-test screening indicated a borderline "positive" for cocaine metabolites and the follow-up gas chromatography/mass spectrometry (GC/MS) confirmatory test indicated a positive result for Benzoylecgonine (a cocaine metabolite) at 330 ng/ml.
Subsequently, we requested our HHS laboratory to provide an explanation and documentation of the screening and confirmatory testing (GC/MS), if performed, during the initial analysis procedures for Specimen No. 107-700-6464-0. In the meantime, we independently verified that the subject blind sample provided by our supplier had indeed been "spiked" with cocaine.
A complete file audit was undertaken by our HHS laboratory in order to retrieve the data concerning the initial negative results. However, the HHS laboratory concluded that these particular files had been misplaced and no further explanation for the incorrect initial results for this blind performance test is available.
