OpenSpecimen allows administrators to set up label formats for auto generating unique participant protocol ID(PPID) and specimen labels. For more information, refer to Label configuration.

Below are some examples set up at different centers:

Example1:

Level	Example	Comment
PPID	%CP_CODE%_%CP_UID(4)%	This will generate a PPID of the sort: GC_0001 where GC is the collection protocol code followed by 4 digit unique sequential ID within the protocol.
Primary Specimen Label	%PPI%.%SP_TYPE%%PPI_UID%	This will generate a label of the sort: GC_0001.WB1 – for a specimen with PPI GC_0001, type 'Whole Blood' & 1st primary specimen for the particular participant.
Derivative	%PPI%.%SP_TYPE%%PSPEC_UID%	This will generate a label of the sort: GC_0001.Pl1 – for a specimen with PPI GC_0001, type 'Plasma' & 1st child specimen for the particular primary specimen.
Aliquot	%PSPEC_LABEL%.%PSPEC_UID%	This is generally used for aliquots. This will generate a label of the sort: GC_0001.Pl1.1, for the 1st child specimen of the parent with label 'GC_0001.Pl1'

The label formats used above will not generate unique labels if you have same type of derivative across parents.
