Differences between primaries and aliquots
This section describes the differences between how LDMS treats primaries and aliquots.
| Primary | Aliquot | |
|---|---|---|
| Global Specimen ID | Ends in -00 | Ends in -01, -02, etc. |
| Processing date | Entered by user | Uses value from primary |
| Enrollment | Can be associated with more than one visit or protocol | Must select exactly one associated enrollment |
Certain information can be cascaded from primaries to derived aliquots specimens, so that if the primary is updated users will be asked if they want to update the aliquots as well.
- Frozen date
- Frozen time
- Comments
- Internal comments
- Tech initials
If a comment is cascaded from a primary to an aliquot, it will be added to any existing comment the aliquot already has.
