Participants

A participant is the source for a specimen entered into LDMS.

The participant is typically a person enrolled in a study. Similar terms that you may be familiar with include “patient” and “source”. In LDMS, a participant refers to all of these concepts. This means that a participant does not necessarily need to be a person. For example, a “participant” may be a control sample from which a specimen was created.

In LDMS, a participant will be the first thing that you create when adding a new specimen record. Newly created participants must be associated with a project and an ID1 (or participant identifier).

If a person is taking part in more than one project, that person will be considered two different participants in LDMS.
