OMLO33 Laboratory order for multiple orders related to a single specimen (2.6)
This is the standard HL7 v2.6 spec, with 12 loops and 45 segment positions, as OpenEDI JSON, an ediFabric C# template and an ediFabric Native model. To change it for a trading partner, customize it in the EDI Spec Builder.
Use the OMLO33 spec in your code
ediFabric .NET
Add the C# template and its common files to your project, or reference the template NuGet package, and read OMLO33 files into TSOMLO33 objects. See ediFabric .NET.
ediFabric Native
Native supports X12 today, and HL7 is coming. When it's available, map version 2.6 to this Native model with set_map to parse OMLO33 files to JSON from Python, Java, C or C#. See ediFabric Native.
OpenEDI
Select Customize in Spec Builder to copy the spec under your own name, change it for your partner, and parse files against it in EdiNation, ediFabric Native or ediFabric Cloud. Read about OpenEDI.
Generate OMLO33 classes in Python, Java, Node.js, Go, Rust or C
The OpenEDI file describes each OMLO33 as JSON. To work with OMLO33 data as typed objects, generate classes from the OpenEDI file in your language; the root class is TSOMLO33. The classes keep the loops, segments, lengths and code lists, but not the EDI data formats. Read more in Generate a class from OpenEDI.
