1 Prerequisites
- 1.1 Label Format and Print Settings
- 1.2 Supply Settings
2 Pre-print specimen labels in bulk
3 Use as specimen labels
4 Use as specimen barcodes

The specimen labels are printed in advance in the required format at many sites, packaged into kits, and dispatched to the collection sites. These high throughput sites like to keep a stock of the printed and consumed labels (kits).

The generated labels can be used to identify/track specimens of any participant. You can use it as specimen barcodes or labels.

Prerequisites

Label Format and Print Settings

None of the tokens related to the registration record like PPI, PPI_UID, etc., can be used.
EVAL token with references to the custom fields cannot be used.
To use the %PSPEC_UID% and related tokens, the CP setting, Label Sequence Key, should be set to “Record Names/Labels”. Since records are not created, IDs cannot be used for tracking. Therefore the names/labels should be used for tracking the sequences.

4. Configure specimen print settings:

Supply Settings

Navigate to the CP overview page.
Click on 'Settings' → Supply
Set the supply setting for your CP as follows:

Are supply barcodes used in specimens?	Yes
Use specimen label when barcode is empty	Yes
Barcodes Validation Mode	Strict/Relaxed

Refer to the wiki page for more information on supplies.

Pre-print specimen labels in bulk

You can pre-print specimen labels in bulk even before registering participants.

Navigate to the participant list view page.
Click on 'More' → Preprint Labels.

3. Fill in all the details and click on 'Print'.

4. To check the printed labels, navigate to 'Supplies' → Search for the labels that you generated for your CP.

Use as specimen labels

If you want to use the generated labels as specimen labels and not as barcodes, you need to enable 'User Inputs Allowed' for specimens. This way, you can scan the generated labels during specimen collection.
