# Partial, Appended, Final, and Duplicate Results

Elation uses OBR 1, 2, 3, and 22 to determine whether a result is a more updated result that should replace a partial, another lab panel that should be appended within the same report, or a duplicate.

* If OBR 1, 2, and 3 are the same for the 2 HL7s but the OBR 22 is chronologically later than the original HL7, the second HL7 received will replace the original HL7.
* If OBR 1 and 2 are the same but OBR 3 is different for 2 HL7s, the HL7s will be treated as distinct lab panels appended within the same report so that both result reports can be viewed at the same time.
* If OBR 1, 2, 3, and 22 are identical for 2 HL7s, the second HL7 received will be treated as a duplicate and not flowed into the chart.

Please be sure that the following fields are updated to ensure updated results flow through properly:

| segment | type | opt | Description |
| - | - | - | - |
| MSH 7 | `YYYYMMDDhhmm` | R | Date and time must be greater than the preliminary result |
| OBR 7 | `YYYYMMDDhhmm` | R | Date and time cannot be the same for two HL7s with the same OBR 2 |
| OBR 22 | `YYYYMMDDhhmm` | R | Results Rpt/Status Change Date/Time |
| OBR 25 | char(1) | R | Result Status C = Correction F = Final P = Preliminary X = Canceled |
