Before v5.2, the Order page had a fixed number of fields about the specimen. I.e. specimen type, quantity, and collection protocol. From v5.2, OpenSpecimen supports customization of order specimen page using JSON.
Depending on the project’s need, you can include additional fields including custom fields. E.g. anatomic site, storage location, barcode, etc.
