Every transfer of a medical specimen, pharmaceutical product, or sensitive healthcare item must be documented. This process is known as chain of custody, and it exists to answer one question with certainty at any point: who had this item, and when?
This guide explains what chain of custody means in a medical transportation context, why it matters, and how healthcare providers can evaluate whether their courier's documentation practices are actually sufficient.
- ✓Chain of custody is the documented record of who handled an item at every step of transport.
- ✓Gaps in documentation can compromise specimen validity, legal standing, and patient trust.
- ✓Digital tracking has made chain-of-custody documentation more reliable than paper logs alone.
- ✓Healthcare providers should confirm their courier's specific documentation process, not assume it exists.
What Is Chain of Custody?
Chain of custody is a documented, unbroken record of every person who handled an item — and when — from the moment it's collected to the moment it reaches its final destination. In medical transportation, this typically means a log capturing pickup time, handler identity, transfer points, and delivery confirmation, often paired with a signature or digital confirmation at each step.
Why Chain of Custody Matters
For laboratory specimens, chain of custody protects the validity of test results — if there's a question about whether a sample was mishandled or substituted, an intact chain of custody resolves it. For pharmaceuticals, especially controlled substances, chain of custody is often a regulatory requirement, not just best practice. And broadly, it protects healthcare providers from liability by creating an accountable record of exactly what happened to a sensitive item.
Risks of Poor Documentation
- ✓Specimen results that can be challenged or invalidated due to handling gaps
- ✓Regulatory exposure, particularly for controlled substances
- ✓Difficulty resolving disputes about lost, delayed, or damaged items
- ✓Erosion of trust between healthcare providers and their logistics partners

Specimen chain of custody typically starts at collection, where the sample is labeled and logged, continues through courier pickup and transport (often with temperature and time tracking), and ends at laboratory receipt, where the lab confirms condition and logs intake. Every gap in this sequence is a point where a specimen's integrity could be questioned.
Technology and Digital Tracking
Paper logs are still used in some settings, but digital chain-of-custody tracking — timestamped GPS data, digital signatures, and photo confirmation at pickup and delivery — has become the more reliable standard. Digital records are harder to lose, easier to audit, and create a clearer record if a dispute ever arises.
Best Practices for Healthcare Providers
- ✓Ask your courier directly how chain of custody is documented — paper, digital, or both
- ✓Confirm temperature and time tracking for sensitive specimens
- ✓Request access to delivery confirmation and handling records when needed
- ✓Treat a courier's chain-of-custody process as a real evaluation criterion, not an assumption
Chain of Custody Standards in the Triangle's Healthcare Network
With multiple major health systems and independent laboratories operating across Raleigh, Durham, and Chapel Hill, specimens often move between facilities that aren't part of the same network — making documented chain of custody even more important. A courier with consistent, digital tracking practices reduces ambiguity regardless of which facilities are involved.
