  • Just checking if i'm right.

    Hi All

    A laboratory provided me some hl7 version 2.4 ORU^R01 files for test purpose

    In 2 files i have a obx.2 segement with TX, and in the obx.5 i got a lot of character.
    It''s look's like they have generate automaticly the value
    But in this value's they have put this ^

    MItrh think it's a Component Separator

    And if i'm right it has nothing to do at this place

    Is it true ?


    This is one of the OBX segment

    If they send the HL7 message with the MSH segment beginning "MSH|^~\&|..." then they are stating that the "^" will be the component delimiter everywhere that it appears in the message. An application that sends HL7 compliant messages may use some other character in that posiition if the "^" is to appear in the message as itself.

      ... except when escaped, of course - in this case with '\'. Looks like they forgot to escape special characters in obx.5 there (not only '^' but also '\')

        It looks like they scrambled or crypted the text.

        They should avoid the 5 characters with special meaning in HL7, or escape them correctly.
