creating an NTE segment rom OBX-5

I am working on writing a code to iterate and increment through the OBX-4 e.g. 1.1, 1.2,1.4 to create an NTE segment concatenating the values in obx5. This also occurs for 2.1. 2.2, 2.3 etc. Please I need some help with writing the script.

what the inbound obx looks like

what the outbound NTE should be. The NTE is created from the looking at the obx4, and concatenating the obx5 1.1,1.2,1.3 or 2.1, 2.2, 2.3 etc.

NTE|1|| Specimen Description Stool

Are you parsing the inbound message to an hl7 table defined by a VMD? Would make sure your OBX segments belong to a segment group that includes NTE segments, then create a loop:


for i=1,#MessageIn.OBXGROUP do
MessageOut.OBXGROUP[i].NTE[3] = MessageIn[i].OBX[5][1][1] .. MessageIn[i].OBX[5][1][2] .. etc.
end


if you’re looking to get fancy with the concatenation I personally would write it out as it’s own function that you send the contents of OBX-5 over to that sends back what you want in NTE-3:

MessageOut.OBXGROUP[i].NTE[3] = MyCatFunction(MessageIn[i].OBX[5])


forgive my syntax just demoing the concept, hope it helps.
