Observation 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 (depending upon the specific case) until they are final.
A | Amended based on adjustments provided by the Placer (Physician) regarding patient demographics (such as age and/or gender or other patient specific information |
B | Appended Report - Final results reviewed and further information provided for clarity without change to the original result values. |
C | Record coming over is a correction and thus replaces a final result |
D | Deletes the OBX record |
F | Final results |
I | Specimen in lab; results pending |
N | Not asked; used to affirmatively document that the observation identified in the OBX was not sought when the universal service ID in OBR-4 implies that it would be sought. |
O | Order detail description only (no result) |
P | Preliminary results |
R | Results entered -- not verified |
S | Partial results. Deprecated. Retained only for backward compatibility as of V2.6.(Deprecated.) |
U | Results status change to final without retransmitting results already sent as 'preliminary.' E.g., radiology changes status from preliminary to final |
V | Verified - Final results reviewed and confirmed to be correct, no change to result value, normal range or abnormal flag |
W | Post original as wrong, e.g., transmitted for wrong patient |
X | Results cannot be obtained for this observation |
