Blood Sample Chain of Custody (Forensic / Legal)
Log every blood sample handoff — released-by, received-by, time, condition and location — for a forensic / legal workflow. Builds a court-defensible, tamper-evident chain, 100% offline.
Record every transfer of a blood sample — who released it, who received it, when, the storage condition (2–8 °C, upright) and the location. Built for phlebotomy and haematology teams who need a court-defensible, tamper-evident chain. Each handoff is an immutable row you can export to CSV; nothing leaves your browser.
Every transfer should be recorded as soon as it happens. A gap in the chain weakens the record, so log received-by and condition at the moment of handoff. Export to CSV for your LIMS, auditor or case file.
This is a record-keeping aid, not a legal compliance system. Controlled-substance handling is governed by your national authority (e.g. DEA, Home Office, NDPS). Keep the official bound register your regulator requires and reconcile against it.
Free blood sample chain-of-custody log for a forensic / legal workflow: time-stamped handoffs, condition and location, exportable to CSV — entirely offline.

Frequently asked questions
What is a chain of custody for a blood sample?+
A chain of custody is the chronological, documented record of everyone who handled a blood sample from collection to disposal — each transfer recording who released it, who received it, when, and the storage condition. An unbroken chain is what lets phlebotomy and haematology teams (and any reviewer) trust that the sample's identity and integrity were preserved.
Why does specimen condition matter in the custody record?+
Because integrity depends on it. A blood sample should be kept 2–8 °C, upright; if a transfer breaks that — a warm freezer, an exceeded holding time — the result may be invalid. Recording condition at each handoff makes any excursion visible and defensible, and is exactly what accreditation reviewers and courts look for.
Is this suitable for a forensic / legal workflow?+
Yes — this variant is framed for a forensic / legal workflow and aims to produce a court-defensible, tamper-evident chain. For legal use, keep transfers contemporaneous and retain your sealed physical evidence packaging; this log complements, not replaces, your evidence-management system.
Where is the custody data stored?+
Only in your browser, via localStorage — no account, no upload, no third-party server. That keeps donor, patient and case data private and lets the tool work offline in the lab. Export to CSV whenever you need a permanent or shareable copy.
