The DNA Technician (DT) performs, and holds execution responsibility for, laboratory testing operations, instrument operation and maintenance, evidence handling, record keeping, and facility tasks for which the individual is authorized. The DNA Technician also supports Forensic DNA Analysts in tasks that require assistance, including evidence examination and screening. Authorization is granted by the responsible Technical Leader following documented training and competency assessment, and covers named procedures and instruments.
Assigned level (I or II) reflects the breadth of that authorization. Training qualifies the DNA Technician to execute procedures correctly, safely, reproducibility, and under contamination control. Interpretation, evaluation of quality control results, statistical evaluation, and reporting belong to the Forensic DNA Analyst, who holds responsibility for all analytical and interpretive decisions on the data produced.
The DNA Technician executes procedures as written, documents the work completely, and escalates any departure from the expected outcome to the assigned Forensic DNA Analyst or the responsible Technical Leader. All work is conducted in accordance with approved laboratory procedures, FBI Quality Assurance Standards ( QAS ), ISO / IEC 17025, and applicable legal and safety requirements.
