Synthetic operational demo · no patient data

Find where the specimen chain failed.

A rejected sample should not automatically become “the courier’s fault” or “the collector’s fault”. This view follows the evidence across each handover and leaves the case unattributed when the chain is incomplete.

How to use it: pick a network, then open each rejected sample to see which handover failed, or why the case is left unattributed.

Limits. Synthetic specimens, people and networks. This demonstrates operational chain-of-custody reasoning only. It is not a LIMS, diagnostic system or clinical decision tool.

Seeing rejections but not the reason?Send us a month of rejection records. We will show where the chain really breaks and where the evidence is missing.
