Box 300, Lafayette Road , Seabrook, NH 03874 United States Nuclear Regulatory Commission SBK-L-19026/Page 2 cc: NRC Region I Administrator NRC Project Manager, Project Directorate I-2 NRC Senior Resident Inspector Enclosure to SBK-L-19026 Introduction On January 24, 2019, multiple specimens were submitted by NextEra to the HHS Certified Laboratory, Quest Diagnostics in Norristown, Pennsylvania.
On January 25, 2019, a report was issued with a negative NRC panel result. A second, corrected report was issued January 30, 2019 that identified this as an Adulterated specimen due to an abnormal low pH value. Investigation Summary The laboratory performed an investigation, which identified:
* The test data from the original screening (initial testing) batch, performed on January 25th was reviewed along with calibrator and known quality control samples for acceptability and correct interpretation.
The calibrator and known quality control samples satisfied acceptance criteria.
* Fresh aliquots were removed from the specimen bottles and the aliquots were tested again in a second screening batch.
* Additional specific gravity and pH testing were performed, as indicated by the specimen validity test results in this second screening batch. The subject specimen had a pH value in the adulterated range on this second test.
* The data from the original and second screening batches were compared for consistency.
Based on this comparison, it appeared that the forensic processing technician did not properly transfer (aliquot) all of the original specimens to the correct sample cups causing this specimen to have the incorrect results.
* The forensic processing technician who aliquoted the batch was interviewed.
Corrective Actions The laboratory has taken the following corrective actions. 1. This incident was _reviewed with the appropriate staff. 2. The forensic processing technician who aliquoted the original screening batch is undergoing retraining and will be subject to competency evaluation when the retraining is completed.}}
