- Entity IDs are unique within the assay (and a study can have many assays)
- Replicates vs. Run
- need planned (ei.xpt) separate from the actual (gt.xpt)
- If tests run at the same time, they are replicates and are assigned the same RUNID
- If tests are run at separate times, they are runs and the RUNIDs are distinct
- Different runs would be expected to have different ENID and GTDTC values. In ei.xpt, these are distinguished by different RUNID values.
- Entities that are replicates of each other would be expected to
- have different ENID values
- be in the same trial set (SETCD values)
- have the same RUNID values
