Default 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
HTML Code:

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 '\')

mourisj is an unknown quantity at this point

It looks like they scrambled or crypted the text.

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