LAB SYSTEMSINDEX

Map the system. Preserve the evidence. Test the handoff.

Operating domain

Operating domain: Sample identity and chain of custody

The control system for assigning identity, preserving parent-child and container relationships, recording location and custody, managing quantity and condition, and retaining every material transition from receipt through disposition.

What this domain asks

The control system for assigning identity, preserving parent-child and container relationships, recording location and custody, managing quantity and condition, and retaining every material transition from receipt through disposition.

The domain should retain its own evidence, decision owner, materiality criteria, exception path, and consequence even when it shares organization identity, workflow, or technology with adjacent domains. Aggregation can support oversight; it should not erase the evidence behind different risks or operating outcomes.

Buyer questions

  • Which identifier is authoritative at each boundary?
  • How are splits pools derivatives and re-labeling retained?
  • What evidence records receipt transfer storage and disposal?
  • How are quantity condition and temperature exceptions handled?
  • Can a result be traced to the exact material and process history?

Evidence boundary

Lab Systems Index provides market, standards, regulatory, product, and operating research. It does not validate a computerized system, certify Part 11 or GxP compliance, accredit a laboratory, approve a method, determine scientific validity, interpret patient results, or replace laboratory, quality, validation, regulatory, security, legal, data-integrity, or scientific review. A provider's documented capability can identify a research candidate but cannot establish buyer-specific adequacy for this domain.
