    The official UCUM specification (http://unitsofmeasure.org/ucum.html) states that text contained inside the curly braces “do not contribute to the semantics of the unit but are meaningless by definition”, so I don’t believe it matters whether you use {cells}, {Cells} or {CELLS}.

    Hope this helps.

    The example units field is not part of the official LOINC term, so you should make your decision on the Property field which is ACnc.
    As you pointed out, there can be a number of different reporting units for a given analyte. The example units field is not intended to be “suggested” units, but is just an example of the type of units that might be resulted for the term.

    Hope this helps.

    You will need to request a term for the mumps soluble antigen. Please be sure to send a package insert along with the submission.

    Good catch. We already caught this problem and have removed the incorrect units for the next release.

    Thanks for the clarification. The system for the following code is cervicl mucos and I think you can assume it means the same as cvx.
    21414-8 – Neisseria gonorrhoeae DNA:Pt:ACnc:Cvm:Ord:Probe.amp.tar

    The test that you cited does not differentiate between Chlamydia & GC, so the LOINC code for a cervical specimen is
    45068-4 Chlamydia trachomatis+Neisseria gonorrhoeae DNA:Pt:ACnc:Cvx:Ord:Probe.amp.tar.

    Hope this helps.

    Un-amplified probes usually detect rRNA, not DNA. What is the name of the test kit that you are using?

    As I mentioned in the previous reply, we suggest that you ignore the UNITSREQUIRED field.

    Our goal is to have EXAMPLE units for most of the terms that have scale = Qn. Unfortunately, units were not supplied for many of the earlier submissions. A couple of years ago, we made units mandatory for submissions, and the more recently created terms do have the example units field populated. We have also been gradually filling in missing example units when we find out what labs are actually using.

    Note that I said EXAMPLE units. We do not intend this to mean that these are the only units that can be associated with a LOINC term.

    I noticed that you used SUBMITTED_UNITS in your review. I think if you ignore UNITSREQUIRED and use EXAMPLE_UNITS instead of SUBMITTED_UNITS, you’ll find that the majority of Qn terms have units.

    Hope this helps.. Kathy

    The UNITSREQUIRED field is defined in the LOINC Users’ Guide as “Y/N field that indicates that units are required when this LOINC is included as an OBX segment in a HIPPA attachment. Since the field was added to the LOINC database, there has not been much activity from the attachment folks and I believe that at the present time we are not populating the field for new terms.

    We recommend that you disregard the UNITSREQUIRED field.

    Hope this helps.. Kathy

    The correct way to represent this concept in LOINC is to use “Signal/Cutoff” in the component and “Ratio” as the property.

    I’m not sure where you get “relative density” from (“property is ratio (relative density)”). Could you explain what you mean?

    For questions like this, where you feel LOINC has not represented something correctly, I suggest that rather using the forum, that you use the contact LOINC form (http://loinc.org/contact-loinc).

    We’d like to see a package insert. Can you provide one, or point to a URL for a package insert or reference information. Thanks.

    It appears that no existing LOINC code fits your purpose, so I suggest that you submit a request for new terms. Please review Appendix D of the LOINC User’s guide for guidance on how to request new terms.

    These may need to be local codes, but I can respond better if I could see and example report and product insert.

    We have recently decided to include the gene name(s) in the component along with the organism name when the gene is specific for one species or genus or the word “bacterial” when the gene crosses different species.

    For example:
    – Staphylococcus aureus enterotoxin B (seb) gene (PROPOSED)
    – Bacterial aminoglycoside resistance (aacA) gene
    – Bacterial shiga-like toxin 1 (STX1) gene

    Hope this helps
