FALSE NEGATIVE QUALITY ASSURANCE TEST
The following information was provided by the licensee via phone and email:
"Contrary to the requirements in 10 CFR 26.137(b), a Health and Human Services (HHS) certified laboratory returned a blind specimen result that was inconsistent with what was expected.
"On November 14, 2024, blind specimens from the same lot number were sent to the two contracted HHS laboratories. On November 27, 2024, one of the labs reported unexpected results while the other laboratory reported the expected results (positive for opiates). At approximately 1415 CST on December 3, 2024, the lab report was reviewed by the fitness-for-duty medical review officer (MRO) staff at the South Texas Project and the inaccurate result was identified. At approximately 1510 CST on December 3, 2024, MRO staff contacted the laboratory to discuss the testing discrepancy and directed the lab to retest the specimen. The MRO staff also requested that the laboratory initiate an investigation to determine the reason for the inaccurate result.
"10 CFR 26.719(c)(3), reporting requirements state, 'If a false negative error occurs on a quality assurance check of validity screening tests, as required in 26.137(b), the licensee or other entity shall notify the NRC within 24 hours after discovery of the error.'
"The licensee has notified the NRC Resident Inspector."
