    Welcome to the discussion forum for LOINC Groups. We’d like to hear your feedback on the file format and the LOINC Groups that have been created. Additionally, we’d love to know how you intend to use this artifact and any suggestions for new LOINC Groups.

    The new grouping of loinc codes is a great new feature.
    Given it is in alpha:
    What is the roadmap for it? Beta by October 2017?
    Full production in Jan 2018?

    Since this is a new space for LOINC, the LOINC team is very interested in community feedback, so we will be organizing methods to do so over the course of the next several months. The current plan is to release another version (hopefully Beta, but perhaps Alpha 2 depending on the feedback) with the December 2017 LOINC release.

    New “human friendly” view of LOINC Group File posted

    Our colleagues at NLM thought it’d be nice to explore the content of the LOINC Group file in an Excel spreadsheet with the subtotal function showing the counts of each group.

    We’ve posted this spreadsheet view here:

    LOINC 2.61 GroupFile Alpha 1 grouped with counts
    requires a free loinc.org login

    With this format you can easily expand and collapse the groups in a tree-like structure.

    Notes:
    This spreadsheet has the columns for parent group and other fields hidden.
    Also, don’t try to import this spreadsheet into a database – you’ll get the subtotal rows too. Better to use the main release format: LOINC Group File, Alpha 1

    Do you have groups for an analyte regardless of unit of measure?

    Very nice job, once LOINC GROUP is completed, it could be used in Thai’s medical reimbursement system in order to drive all hospitals to use LOINC in HIS.

    Good to see this work. Here at Wolters Kluwer Health we are evaluating its value in helping enhance our CDS capability. I hope to have the chance to engage with others as we determine if this grouping can help us solve our issues with the flat, non-hierarchical nature of LOINC.

    Hi Charles –

    As you probably know, LOINC codes are not specific to a particular unit of measure. The Property does constrain which units are allowable for a given LOINC term. For example, and mass/volume unit could be used with a LOINC term that has a Property of MCnc. The units fields in the LOINC table are all meant as “examples”; they are not normative

    We are making a few high level groups for LOINC codes that collect terms across Properties. One area of focus initially are groups that collect MCnc and SCnc terms for the same analyte. With the molecular weight, such a group would allow equivalence.

    Take a look at the ParentGroup: LG55-6 MassMolConc

    It forms Groups that pull together measures of the same analyte with either MCnc or SCnc:

    LG10153-1 Bilirubin|Pt|Urine|Test strip|MassMolEquiv|584.662 g/mole
    20505-4 Bilirubin.total [Mass/volume] in Urine by Test strip
    41016-7 Bilirubin.total [Moles/volume] in Urine by Test strip

    I’ve got a question for our public health colleagues using LOINC. Would it be useful to have groups that pull together tests on isolates from “normally sterile sites”?

    If so, is there an agreed list of such specimen sites? (I see, for example, one from MN: http://www.health.state.mn.us/divs/idepc/dtopics/invbacterial/sterile.html)

    Amazing job! Maybe it could facilitate the development of common code subsets like Top2K+ in other countries/regions etc.

    Multiple levels of granularity may be needed for various use cases.
