LOINC Panels are collections of terms to represent specific sets of information

Beginning with version 1.0, the LOINC database was expanded to include order sets/panels. We use the word “panel” to mean collector terms that are linked to an enumerated set of discrete child elements. Across domains, this generic concept of a collection might be called a battery, form, data set, etc. For example, these collections can be a laboratory battery of tests, a group of findings from a procedure such as an EKG, and forms or assessments related to health that are completed by patients and/or providers. The same general panel structure in LOINC is used to represent all of these kinds of collections.

LOINC Panels contain a specific structure with optional attributes, and depending on the type of panel, can include attributes values such as form coding instructions, skip logic, optionality, and nested panels.

Panels encompass many domains of content, including:

  • Laboratory panels
  • Clinical Assessments, Scales, and Measures
  • Clinical Documents and Summary panels
  • Diagnostic studies (non-lab) panels
  • US Government panels (including the CMS LT-PAC instruments MDS, IRF-PAI, LCDS, and OASIS)
  • Survey Instruments

For more information on modeling of Panels in LOINC, refer to Chapter 7 "Panels (Batteries)" of the LOINC Users' Guide.

Panel Browser

You can browse through LOINC Panels by numerous categories, each containing subcategories indicating the panels intended use.

File Descriptions

PanelsAndForms.csv

This file contains all of the panels in LOINC, with one row representing each individual term within the panel along with information specific to the instance of that term within the panel, including the display name for the specific form, cardinality, skip logic and form coding instructions.

Some LOINC panels contain child panels nested underneath. For the nested panels, the row for each term within that panel will have the value for the immediate parent in the "Parent" column. And for the nested panel terms themselves, the panel terms that contain them will be contained in their "Parent" column.

This hierarchical structure uses the adjacency list model. It is represented in the file by the ParentID, ID and SEQUENCE fields. The root, or top level, records in the file are those records where the ParentID = ID.

For example, if Panel A contains Panel B and C, and Panel B contains Terms 1, 2 and 3 and Panel C contains Terms 4, 5 and 6, this would be represented as:

PARENT CHILD
Panel A Panel B
Panel B Term 1
Panel B Term 2
Panel B Term 3
Panel A Panel C
Panel C Term 4
Panel C Term 5
Panel C Term 6

Note that this file is limited to LOINC panel terms and their child elements. LOINC terms that don't exist as part of a panel are NOT included.
