Some studies might be collecting only specimen information with no linkage to the participants. From v4.0, OpenSpecimen supports specimen-centric studies. During protocol set-up, administrators can choose if a study is a participant or specimen-centric study.
Once a protocol is defined as 'Specimen Centric,' the 'Events' tab is hidden in protocol set-up as there is no need to capture participants and visits.
When the user accesses such protocol for data collection, the specimens list page is directly displayed.
Option to create specimen directly is available without linking to participant or visit. You can add multiple specimens of the same or different types by clicking the 'Add Specimen' button.
