# Lab workflow

> Build testing schedules and chain of custody records, and send samples to the lab.

Manage covers the journey from sample to laboratory: build a **testing schedule**
of what to test, and raise **chain of custody** records that track samples to the
lab. Both draw on the **laboratories** and test catalogues set up for your company.

<Callout type="note" title="Laboratories come from Product OS">
  The labs you assign work to, and their test catalogues, are maintained once for
  your company in [Product OS](https://os.gimlabs.io) and reused across every
  project. You select them here; you do not set them up here.
