Observ Result Status
It is a required field. Previous versions of HL7 stated this implicitly by defining a default value of "F." Code F indicates that the result has been verified to be correct and final. Code W indicates that the result has been verified to be wrong (incorrect); a replacement (corrected) result may be transmitted later. Code C indicates that data contained in the OBX-5-observation value field are to replace previously transmitted (verified and) final result data with the same observation ID (including suffix, if applicable) and observation sub-ID usually because the previous results were wrong. Code D indicates that data previously transmitted in a result segment with the same observation ID (including suffix) and observation sub-ID should be deleted. When changing or deleting a result, multiple OBX segments with the same observation ID and observation sub-ID are replaced or deleted as a unit. Normal progression of results through intermediate (e.g., `gram positive cocci') to final (e.g., `staphylococcus aureus') should not be transmitted as C (correction); they should be transmitted as P or S (depending upon the specific case) until they are final.
C | Record coming over is a correction and thus replaces a final result |
D | Deletes the OBX record |
F | Final results; Can only be changed with a corrected result. |
I | Specimen in lab; results pending |
P | Preliminary results |
R | Results entered -- not verified |
S | Partial results |
U | Results status change to Final. Results did not change (don't transmit test). E.g., radiology changes status from preliminary to final |
X | Results cannot be obtained for this observation |
