# Labs

> Set up laboratory locations before catalog and reports.

# Labs

Requires **Lab management** permission.

**Labs** are locations or lab units in your workspace. Catalog tests and reports belong to a lab — set at least one active lab before you create reports.

## Add a lab

1. Open **Laboratory → Labs**.
2. Choose **Add lab**.
3. Enter name and details, then save.
4. Keep the lab **active** so staff can use it in catalog and reports.

## Edit or deactivate

Open a lab to rename or mark **Inactive**. Inactive labs should not be used for new reports; existing reports remain for history.

If another staff member saved the same lab while you were editing, ClinZero asks you to **reload** or **overwrite** so your change does not silently replace theirs.

Unsaved create/edit changes prompt for confirmation if you close the dialog or reload the page.

## Delete unused

You can **Delete** a lab only when it has no reports or notes. Deletion is permanent — type the lab name to confirm.

If delete is blocked because reports or notes still reference the lab, ClinZero offers **Deactivate instead** so the lab stays out of new workflows without removing history.

## Recommended order

1. Create **Labs**
2. Build the [Catalog](/lab/catalog)
3. Create and publish [Reports](/lab/reports)
4. Configure [Printing](/lab/printing)
