  • in reply to: Liddle Syndrome #21012

    Hi Panu,

    Genetic tests in LOINC are typically named based on the genes tested. The disease names should be included as synonyms (related names) so users can find the tests when searching in LOINC. For Liddle Syndrome, these genes are likely SCNN1B and SCNN1G, which we currently do not have codes for in LOINC. We welcome a request for new terms. For information on how to submit a request, please visit https://loinc.org/submissions/.

    Thank you,

    in reply to: System type for Micro Antibody tests #17910


    Yes, we welcome a formal request for updating Systems from Ser or Plas to Ser/Plas. Updates to LOINC terms can be made through the loinc.org website at https://loinc.org/submissions/revisions/. Please provide documentation to support the update request.

    FYI from Page 28 of the LOINC Users’ Guide:

    For many types of tests, the distinction between plasma and serum is irrelevant. When testing on serum or
    plasma is clinically equivalent, the System should be recorded as Ser/Plas, meaning “either Serum or Plasma”.
    Note that the use of a LOINC code with Ser/Plas as the System to report the result of a specific manufacturer’s
    assay does not imply that the given assay is approved for use with both serum and plasma specimens; it simply
    means that the results obtained from testing serum and plasma are clinically equivalent, independent of which
    assay was used. Sometimes the test can only be run on either plasma or serum; the Component will then be
    associated with either Ser or Plas in one observation. If the test can be run on either but the results are clinically different and standardized (a very rare circumstance), two separate tests will be defined in our file, one with a
    System Plas and one with a System Ser. The current LOINC database includes some Ser tests and some Plas tests that should really be Ser/Plas. As we determine that a Ser or Plas test really should have been designated Ser/
    Plas, we will change the designation.

    Thank you!

    in reply to: HCG.beta unit with WHO 5th IS #17303

    Wai Kin Cheung,

    Thank you for your post.

    We suggest the use of test codes without IS in their name and encourage labs to report that information either as text in the method field of the HL7 message or in a comment when they think it is important.

    We have found that laboratories are often inconsistent about the use of the various IS standard in their test names. Additionally, one reason for changing of IS standards is that the control specimens for the existing standard run out. This does not always mean a real difference in the new IS standard compared to the old. Further, the tests for pituitary hormones vary greatly in their test results because of the differences in the fragment and sections of the polypeptides they pick up. So on the one hand, it has been difficult to know what IS standard a given lab is really using when they make a submission to LOINC. On the other hand, differences in test methods create intrinsic noise in these tests.

    So with advice from our laboratory chemistry experts, Regenstrief has decided not to try and keep up with the IS distinctions and should probably discourage the use of the terms with IS in their name.

    We welcome input on these decisions.

    in reply to: 75219-6 Summary registry report #17264

    A summary registry report could represent a collection of patient data included in a registry or reported to an organization who manages a registry (or database) for a given cause or reason.  The data may then be analyzed by the organization and reported to interested parties (government, etc.) who would use the results to develop programs, for example, to improve patient care based on the data.

    In addition to the general code – 75219-6, we currently have three codes for more focused/defined registries:

    75609-8            Birth defects registry report       Find      Pt         Outpatient         Doc      {Author Type}

    74264-3            Summary registry report            Find      Pt         {Setting}           Doc      HIV

    74198-3            Summary registry report            Find      Pt         {Setting}           Doc      Trauma



    in reply to: What is Coronary Calcium actually? #16680

    You can find information about coronary calcium here: http://www.nhlbi.nih.gov/health/health-topics/topics/cscan/

    I agree that it doesn’t appear LOINC has an existing code for reporting the calcium (or Agatston) score. You can send a formal submission to submissions@loinc.org. See http://loinc.org/submissions for more information.


    Hi Barry,

    We have a few codes for HBA1 and HBA2 gene mutation analysis that may work. They can be viewed here: http://search.loinc.org/search.zul?query=hba1+or+hba2+or+hbz*. If the lab is testing for a specific mutation or deletion, we recommend mapping to the corresponding LOINC code (e.g, LOINC 55247-1).

    Currently we do not have codes for HBZ gene testing. We welcome a formal submission sent to submissions@loinc.org. For more information, see http://loinc.org/submissions.

    The current model for how LOINC names molecular genetic tests is described in the User’s guide, Section 3.9: http://loinc.org/downloads/files/LOINCManual.pdf

    Hope this helps!

    in reply to: Licensing of instruments #16665

    Additional permission is not needed if the external copyright notice (when provided with a term) is included in the publication.

    Section 9 of the LOINC Copyright Notice and License (see http://loinc.org/terms-of-use) discusses the terms to which users may incorporate LOINC content into an implementation guide or other technical specification.

    Specifically, Section 9e states users are required to either:
    i) Include the EXTERNAL_COPYRIGHT_NOTICE, or
    ii) Exclude information from the rows that include third party copyrighted content (e.g., third party survey instruments and answers). If third party content is included, users are required to comply with any such third party copyright license terms.

    in reply to: Codes vs scores for scales #16668

    We agree, typing the values as integers seems appropriate.

    in reply to: CBC Panels #16640


    Thanks for your comments and suggestion about replacing “W” to “with” in the long common name of LOINC codes. The W does stand for with, but this may not always be clear. We will pass your suggestion along to the LOINC team.

    in reply to: reporting CT values in molecular tests #16645

    I agree that the cycle or cross threshold (CT) value for real-time PCR is not an interpretation. I suggest requesting a quantitative code similar to the following since the result is numerical:

    Salmonella enterica DNA Threshold Pt XXX Qn Probe.amp.tar

    What type of document codes are you looking for? Can you provide an example?

    Information for requesting new LOINC codes can be found here: http://loinc.org/submissions

    Information on how to submit a term request through RELMA can be found in Appendix A of the manual: http://loinc.org/downloads/files/RELMAManual.pdf

    Some of the requested information (package insert, units, etc.) for a new term is specific for laboratory terms (vs. document type codes). For document type codes, please include example reports, descriptions for terms, and any other relevant information about the term(s).

    in reply to: General comments/findings for molecular test. #16631

    Hi Barry,

    For free text results, we recommend using narrative codes only. We have a few other codes that may work:

    50398-7 Narrative diagnostic report Imp Pt Bld/Tiss Nar Molgen
    62365-2 Diagnostic impression Imp Pt XXX Nar Molgen
    69047-9 Geneticist review Imp Pt XXX Nar
    69965-2 Clinical cytogeneticist review Imp Pt XXX Nar
    59465-5 Pathologist review Imp Pt XXX Nar

    I also agree that it doesn’t make sense to use a “genetic screen” code for a confirmation test. If you are unsure or think you need a new LOINC code, we welcome a submission (http://loinc.org/submissions). Please send example reports (de-identified) along with your requests.

    Possibly of interest, the HL7 Clinical Genomics Workgroup is working on developing and implementing several models for reporting genetic testing results (for cytogenetics, genetic variations, gene expressions) as well as a guide for the overall Genetic Testing Report (GTR).

    in reply to: Sequencing Pathogens #16624

    It is possible that LOINC does not have existing codes for the examples you provided. Without additional testing information, it is difficult to give more direction. We welcome submissions for new term requests (see http://www.loinc.org/submissions). With the submission, feel free to propose what you think should be included in the six parts (Component, Property, Timing, System, Scale and Method) of the LOINC term. Package insert (test kit information), test descriptions/significance of testing, and example results/reports are often necessary for the creation of a term.
