Test results are usually sent by the laboratories in the HL7 format.  This protocol allows the Incisive application to automatically send acknowledgement replies back to the laboratory to indicate that the tests have been received.  The laboratories match the acknowledgement messages with the original test result.

If no acknowledgement is received by the laboratory then the test result is resent.

The acknowledgement files are automatically created when the test results are imported into the database - not when the tests are read by the Provider. 

1. Check the importing application (HL7.exe or HL7AUS.exe) is working.  On the computer that receives the incoming test results, use Task Manager to see if there are either multiple copies of the files running or if either of these files are not responding.  Use End Task to cancel multiple or non-working instances of these files.
2. Manually restart the HL7.exe or HL7AUS.exe (in the SPMWIN directory)
3. Check that a scheduled task has been set up to run the HL7.exe or HL7AUS.exe files on a regular basis (hourly) or, if there is a task scheduled, check that it is working correctly.
4. Once the reason for the acknowledgements failing has been established and rectified you can use the 'Strip Duplicates' option in the Incisive application to remove duplicate or multiple copies of the same test result on the patient's file.  Go to Utilities -> Repair -> Data Repair and use the 'Strip Dupl' option.
   CAUTION - this should only be used after discussion with the Incisive Helpdesk.
