Physical samples
Follow the specimen and its results.
Connect a collected specimen to its handling history, the portions prepared from it and the laboratory work performed on each.
Preserve the collection
Record what was collected, where it was found and who documented it. Gaps in the history remain visible.
Follow each portion
When a specimen is divided or prepared, keep each resulting portion distinct. Each can have its own handling history.
Scope the finding
A result belongs to the portion that was analyzed. Preserve the method, units, reported uncertainty and any detection limits.
In the Meridian showcase
One specimen. Two different paths.
Meridian’s fictional specimen is divided into two portions. One has a laboratory result; the other is retained. Switching between them shows why the result cannot be assigned to both.
Explore the fictional caseA traceable record helps someone review the work. It does not verify possession, specimen identity or origin. The implementation guide distinguishes the available sample-provenance checks from the newer laboratory contracts shown in the showcase.
Kinds of source material
Follow the source.
Work with an instrument capture, recorded account, released document or collected specimen. Each has a distinct path through the standard.
Each guide keeps the source’s context and interpretation limits visible. The documentation describes the available checks and release status.
