12--SEQSequence NumberNum
Identifier

C70710A number used in combination with the identifier of the subject of the observation to uniquely identify a record within a domain.

May be any valid number (including decimals) and does not have to start at 1. Datasets that do not contain subject data, such as the Trial Summary (TS) domain and the Device Tracking (DT) domains, use --SEQ as a sequence number to ensure uniqueness within the dataset.
