DG1 IN1 segments missing from ORU^R01

[VijrumbhanM]

Hi Team,

I am new to HL7 format, and i have been asked to work on parsing HL7 data into dataframes using python.
i have started to use hl7apy lib. i have parsed some files successfully but have been facing problem in parsing one of the files (file attached).
the parsed message from hl7apy parser returns parsed messages but DG1 and IN1 are missing.

Test_1.txt

i am passing the entire message as string. below call that i use to parse data. can you help in understanding what is going wrong

from hl7apy.parser import parse_message

hl7_message=read_file_from_directory("Test_1.hl7")
hl7_messages=hl7_message.replace('\n','\r').split("MSH|")
message = parse_message("MSH|" + hl7_message,validation_level=VALIDATION_LEVEL.TOLERANT)

Regards,
Vij

Hi @VijrumbhanM,
the parse_message function tries to parse the message gathering the segments by groups using the official structure of the message. You can see the structure by checking the files hl7apy//messages.py/groups.py/segments.py etc...
Seems that those segments don't belong to the message ORU_R01 so hl7apy cannot include them in the groups.
If you want to parse the message ignoring grouping you can add the find_groups=False parameter to the parse_message function.
Hope this helps.

PS: why are you splitting the message by MSH. Yoi can just pass the result of hl7_message.replace('\n','\r') ti parse_message
