The Pretrial Services Agency for the District of Columbia (PSA) runs an in-house laboratory, managed by the Office of Forensic Toxicology Services (OFTS), which handles drug testing for pretrial defendants under PSA's supervision, supervisees under CSOSA's supervision (including those on probation, parole, and supervised release), and individuals ordered to test by the D.C. Superior Court Family Court. This laboratory is certified by the U.S. Department of Health and Human Services in accordance with the Clinical Laboratory Improvement Amendments (CLIA) and is staffed with experts in forensic toxicology, forensic science, medical technology, chemistry, and biology.
The laboratory also engages in applied forensic research, developing improved testing strategies, implementing cutting-edge technologies, enhancing operational efficiency, and fostering partnerships with the scientific and social research community.
