Forensic labs face scrutiny over unexpected test results

During a recent government meeting, significant updates were provided by various forensic laboratories regarding proficiency tests and casework notifications.

The Monroe County forensic toxicology laboratory reported an initial notification of a closeout concerning a report on oxymorphone that did not conform to standards. An amended report was subsequently issued, confirming that no other cases were affected. Additionally, the laboratory faced an unacceptable proficiency test result but reanalyzed the sample, achieving acceptable results. The laboratory director confirmed that stakeholders, including the defense community, were notified, despite lacking direct contact information for the defense in this instance.

Moving on, the NASA County Office of the Medical Examiner's Division of Forensic Services highlighted unexpected results from a 2023 quarter 3 DNA proficiency test, where certain testing aspects were not performed or reported. Furthermore, there was a notification regarding an inadvertent custody transfer of the laboratory's information management system, which is currently under investigation.

The NASA County Medical Examiner's Division of Forensic Toxicology reported an unexpected proficiency test result involving acetone, leading to a suspension of quantitative reporting while further investigations are conducted. Additionally, an analyst previously removed from drug screening has been retrained and authorized to resume their duties after a six-month monitoring period showed no deviations from established policies.

The New York City Office of Chief Medical Examiner's Department of Forensic Biology also reported unexpected results from several proficiency tests, indicating ongoing challenges in maintaining testing standards across forensic laboratories.

These updates underscore the importance of rigorous quality control measures in forensic testing and the commitment of these laboratories to transparency and accountability in their operations.
