Office of Forensic Toxicology Services

Felix Adatsi, PhD, Director


The Office of Forensic Toxicology Services (OFTS) operates PSA’s in-house laboratory (Lab), which conducts drug testing for pretrial defendants under PSA’s supervision, offenders under CSOSA’s supervision (i.e., persons on probation, parole, and supervised release), as well as respondents ordered into testing by the D.C. Superior Court Family Court. The Lab is certified by the U.S. Department of Health and Human Services/CLIA and is staffed by professionals with credentials in forensic toxicology, forensic science, medical technology, chemistry and biology. When requested, the Lab’s toxicologists and chemists provide expert testimony in support of analytical results and interpretation presented in court or at administrative hearings. Lab scientists interpret results for new or residual use for over 2,000 defendants/offenders each month.
