Lab Results History
To retrieve patient laboratory results information from the Server.
The _Lab Results History_ query returns laboratory results information in the form of the Segment Pattern Response corresponding to the ORU^R01 _ unsolicited transmission of an observation message. It returns all of the results which meet the criteria defined in the QPD _ Query Parameter Definition Segment of the RSP^R11 _ Segment Pattern Response message.
If a LOINC code is used as one of the operands of the input specification expression, all of the other OBX segments which are part of the same OBR as the selected OBX will be returned along with the selected OBX. In other words, if an OBX segment that is part of a panel is selected by the query, the entire panel will be returned.
