    A second thought, if you only need drug testing, in the search browser enter      class:drug/tox  to get the subset of 8495 LOINCs. Entering class:drug/tox urine ord narrows more to urine testing with positive/negative results with 875 LOINC results.

    Best regards,

    Hello Tom!

    If you’re just getting started in mapping to LOINC, may I suggest viewing some of the tutorials available under the learning section of the homepage. May I suggest the “Get Started” and “Introduction to LOINC” videos? This will help orientate yourself to begin translations.

    I would recommend having your list of defined assays with mnemonic, display names, specimens, units of measure, result type and method if possible in one file. LOINC uses six attributes of Component, Property, Timing, Specimen, Scale and Method (but only specimen would be found as that name from your laboratory information system). Use the search.loinc.org browser to plug in a keyword of the assay name and specimen and possible subsets will float into view for your selection. From there I would follow your assay list to see the scale (quantitative, ordinal, etc).

    If you need further assistance, please reply in here.

    Thanks,

    Pam

    Hello Hiu (and many thanks to Tim for augmenting the original post),

    Since report option 2 is using a more granular approach, with LOINC terms for each section, I would suggest saving 93193-1 for reporting option 1 solely.

    There are a series of department role review terms, one of which may apply to this Clinical Interpretation. Presuming this is not a pathologist interpretation or a medical director interpretation, which have their own LOINC terms.

    You can locate the department role review terms in search.loinc.org by entering   review  xxx  nar

    I would suggest using 69047-0 Geneticist review of results

    Thank you for considering,

    Pam

    Hi Bien,

    You might be interested in the CLASS field of each LOINC; here is the legend to those abbreviations: https://loinc.org/kb/users-guide/classes/

    Also, there are attempts to create an ontology of the terms. You can read about it in the User’s Guide https://loinc.org/kb/users-guide/document-ontology/   or under Relma you can visualize the hierachy by clicking on the Hierarchy & Search Limit tab, then clicking on one of the specific Hierarchy tabs. Trying pasting in 19769-9 in each of the tabs to see what resonates for your project/application.

    All the best,

    Pam

    Hello Omar,

    I searched LOINC for “dialysis panel” to try and answer your question. There is a ESRD dialysis adequacy panel, but it doesn’t contain all that you mention. You are welcome to submit through the template at loinc.org/submissions.

    Have a great day,

    Hi Emily,

    We just completed the uptake of content at 3M and didn’t encounter this issue. The theory of issuing terms without the Mod10 check digit is still adhered to. I’ve got the LoincTableCore open and filtering on either component or the beginning of a LOINC term.

    I suspect there is a corruption or format issue with the download at your facility. Will you have someone investigate? The 444** numbers listed for Amdinocillin in your email are for other chemistries.

    Thank you,

    Pam

    Hello Alla,

    The chosen example codes include clinical and lab topics. While unsure of your full use case, may I suggest you also include some logic for the property? These included Numeric Ratio, Time Stamp, Angle and Dosage. Cruise through the browser with Property:Angle or Property:NRAT to gain insight to the intent of the content. This content is very complex, and I would caution making short assumptions based on one attribute.

    The TmStp property is explained for not having units by having the format is Date and Time.

    Angle property is similarly self explanable.

    Numeric Ratio property usually has insight from the analyte/component.

    Wishing your project well and hope this helps

    Dosage property could have different units based on the form of the medication (mg/mL syrup, mg tablet, mg/mL injection, etc.)

    I can’t speak for Regenstrief on when it would be accomplished, but there has been past mention at public meetings where the units of measure weren’t always submitted by the end user; it is a project planned to fill out down the road.

    Hello Francois,

    I could not locate the compound in LOINC either. A submission will be the best solution.

    Kind regards,

    Hello Marc,

    Jozef Aerts of XML4Pharma has presented on his work with LOINC and CDISC at several LOINC conferences. Presuming his knowledge is a good start in referring you to the right person/agency/institution, I am forwarding your request for information through email. Any responses will be posted back in here for Forum members benefit.

    Sincerely,

    Pam

    Hello Dirk,

    Curious to know the use case and displays of the confirmation CDT test and presuming it’s a different order code from the initial assays? These three variables augment the LOINC’s stance: a display like “CDT Confirmation” along with it being ordered only on initially high results.  91671-8 is conveying the assay, specimen, scale, etc. The business/operational process of only reporting elevated CDT confirmation assay on from the clinician to the governing authorities portrays the severity of the situation.

    As you’re aware, toxicology is the area where Regenstrief has designed Screen and Confirmation methods for differentiation. Only the laboratory information systems having two assays built can use those LOINCs for each drug. Otherwise the methodless term is used where the confirmation overlays the initial screen result in the same field. In those instances, it’s likely a confirmation footnote is added.

    Your team is welcome to submit for a confirmation CDT LOINC if this is an insufficient discussion.

    Have a great weekend,

    Pam

    Hello Katherine!

    Thank you for the example. I would like to refer you to pg 150 in the LOINC User’s Guide “Before you submit”. “Please note that we tend to avoid the use of methods for chemistry tests. We will not routinely accept requests for method-specific chemistry tests. Only in very special circumstances will we distinguish among analytic methods in chemistry. We do distinguish microbiology, serology and coagulation tests by method type. Even here, however, we do not distinguish every variation in method. Look in the body of this User’s guide for information about the kinds of distinctions we make.”

    I recall Dr. McDonald explaining in person that the chemistry arena of laboratory is well calibrated with little variance among sensitivity and specificity. The method attribute can be used to infer a less specific/sensitive method, such as latex agglutination as compared to Western blot.

    You would be perfectly correct in using one of the methodless concepts for cortisol, varying by the units of measure reported.

    For metric (grams/volume), 2143-6 Cortisol:MCnc:Pt:Ser/Plas:Qn:

    For molar (moles/volume), 14675-3 Cortisol:SCnc:Pt:Ser/Plas:Qn:

    Hello Jess,

    I dug down into the RSNA Playbook mentioned on the other point, and refer you to 5.2.1 Aggregation on page 194 of the LOINC User’s Guide. “The syntax for representing greater than or equal to and less than or equal to a specific number of views is “GE <#>” and “LE <#>” respectively.

    I can assure you nothing is vendor related.

    Have a great day,

    Hello Jess,

    If you’re just starting out, may I refer you to the LOINC RSNA Playbook in the User’s Guide? It starts on page 185. If you downloaded the LOINC/RELMA zip file you’ll find it on your local machine at LOINCUsersGuide.pdf

    The formatting of the radiology terms may make more sense to you after reviewing.

    Best regards,
