The Atlas Toxicology Lab presumptive positive result (sample ATL-2026-0442) was contradicted by an independent GC/MS confirmatory test conducted at a separate certified facility on 2026-03-01, which returned a negative result for all tested substances.
Supporting Evidence (1)
Independent GC/MS Confirmatory Test — Synthetic Reference
Confirmatory GC/MS toxicology test conducted at an independent certified facility on 2026-03-01. Result: negative for all substances tested. This reference is synthetic and does not represent a real test result.
Hair follicle toxicology report from Atlas Toxicology Lab. Presumptive positive only; no GC/MS confirmation documented. Report faxed to agency supervisor, not the assigned caseworker. Synthetic reference — not a real lab result.
Evidence Gaps (1)
Chain Of Custody — high priority
Courier receipt for sample ATL-2026-0442 between Example Family Services and Atlas Toxicology Lab is absent from the agency file. Part III of Form FS-115 is unsigned. Without this document, the sample's custody between agency handoff and lab intake cannot be independently verified.
