Performs services in support of the technical activities of the Extraction and Confirmation laboratory by developing and modifying analytical procedures related to testing drugs of abuse, and other investigational drugs.

Develops LC/MS/MS methods through modification of existing methods or by creating entirely new methods. Modifies analytical methods to increase sample throughput, improve robustness and specificity of assays.

Analyzes service member specimens for drugs of abuse, and investigational drugs within the Extraction and Confirmation laboratory by using chemical extraction, derivatization, LC/MS/MS analysis and special tests, when required, under strict chain-of-custody requirements.

Performs review of negative and positive analytical test results produced in the confirmation laboratory. Reviews results for acceptable analytical data, receiving and reporting documentation, chain-of-custody and compliance with standard operating procedures, before release of results. Identifies errors in procedure or analytical process and recommends corrective action prior to releasing data. Ensures that no false positive results are reported to laboratory customers.

Reviews analytical procedures in progress and data produced and provides technical advice and corrections to ensure the validity of results. Reviews intra-laboratory chain of custody forms and corresponding urine sample identification numbers for exactness; makes forensic corrections as necessary according to operating instructions to permit the results to be legally defensible in a court of law. Verifies that all work complies with applicable DoD directives, Air Force Instructions and established HQ AFDTL operating instructions.

Assists other AFDTL staff in developing extraction methods and techniques to isolate drugs. Interprets complex and diverse analytical data and provides actions and/or written reports for solutions. Assist in development and implementation of improved analytical methods or processes for increasing the efficiency and quality of laboratory operations. Assist in solving forensic and analytical problems presented to the laboratory on a day-to-day basis. Provides scientific evaluation / interpretation of drug testing results and analytical methods to section and/or branch chief.

Operates and maintains scientific instrumentation to include Liquid Chromatography/Tandem Mass Spectrometry (LC/MS/MS) analyzers, and other analytical and developmental technologies (e.g. Agilent Rapid Fire and Hamilton STAR) with different data systems, including but not limited to Windows 7, Waters MassLynx, Agilent Mass Hunter and newly developed data systems as necessary.

Monitors reagents and chemical use, maintains equipment and instrumentation, and submits supply orders as required in the extraction and confirmation laboratories to the confirmation supervisor. Projects usage rates and reports usage levels to the confirmation supervisor. Ensures reagents and chemicals are certified before use. Performs both routine and advanced preventive maintenance and troubleshooting on all equipment and sophisticated instrumentation in the confirmation section.

Reports all necessary manufacturer level maintenance support requirements to confirmation supervisor for the purpose of acquiring instrument preventive and repair service per maintenance agreements. Conducts and oversees the performance of daily and routine preventive maintenance on all instruments. Ensures all preventive maintenance is properly documented.

Prepares recommendations for corrective action and coordinates with confirmation and laboratory supervisory personnel. Documents and makes recommendations to resolve exceptions to operating instructions. Analyzes test results to identify statistically significant trends, and assist with developing and implementing recommendations for corrective action.

Complies and adheres to all policies and procedures on safety, computer security, laboratory security, forensic integrity, and test result confidentiality. All practices are conducted in accordance with applicable policies, operating instructions, regulations, AFOSH, and procedures on the following: 1) electrical, fire, and ground safety; 2) prevention of occupational exposure to biological and chemical hazards; 3) computer security, care, and maintenance; 4) data and sample forensic integrity; and 5) laboratory security. HQ AFDTL's operational areas are controlled spaces. Individual is responsible for ensuring all security requirements are adhered to. Stays current with laboratory practices, regulations and policies dictated by laboratory and regulatory agencies. Attends classes, briefings, reads operating instructions, and other training when available, applicable and approved. Absolute forensic integrity must be maintained. Obtains and maintains confirmation laboratory certification in accordance with established laboratory policy. Takes approved corrective action as needed.
