Hi Charles,
I’m unaware of any table Regenstrief provides in this manner. The UCUM documents are descriptions and instructions on translation local unit displays to the standard UCUM format. There are example UCUM tied with terms in RELMA (and therefore extrapolation is possible). In early, early LOINC days, 3M had internally used synonyms of properties to our units of measure domain. Everyone’s foundation has matured with time, and toolsets along with them.
Sorry to not help you more specifically.

pdbanning@mmm.comHi Samuel,
Once you have a good handle on the actual scope (number of terms; orders and results?; departments, etc), the benefactors internally (who will become your enablers if there are barriers), the projects competing for your resources and the desired timeline, it’s probably a good time to start a vendor search. Be sure and know your company’s contracting process, because that time needs to be included, as well as search time. 3M Health Information has stored on the Documents section of the LOINC website a sample project plan (internal or external). I have recently updated it, if you’d like a copy email me.
Hope this helps,

Hello, please review the LOINC User’s Guide section 2.3 for the formal description. I like to think of this attribute as keeping numeric values in distinct aggregates (apples and apples vs apples and oranges). A value of 25 could be 25 mg/dL, 25 mmol/L, 25 IU/L; these are all very different in concentration basis. Having distinct LOINC codes allows the computers to recognize these are not to be placed on the same reference line, nor trend them together.
Hope this helps!

Hi Julian,
Use the first tab, labeled Search, instead of the second tab, Mapping Screen. You’ll have everything you need. If you need the style of the mapping search window, you can just type over the LMOF without incident.Have a happy and safe 4th of July.

pdbanning@mmm.comHi Vincent,
I don’t know how I missed this, very sorry for the delay. Regenstrief has asked for feedback on a particular LOINC Order Panel through the Contact Us page under submissions. I have already turned in feedback on Electrolytes and Arterial Blood gases. They have not been addressed as yet.
Best regards,

pdbanning@mmm.comHello, 3M staffers found this for your consideration:
From the <span style=”text-decoration: underline;”>Manual of Clinical Microbiology, 8<sup>th</sup> Edition, 2003 pg. 1158-1159 </span>:
“Methods that are commonly used to test rapidly growing aerobic and facultative anaerobic bacteria are, for a variety of reasons, unsuitable for testing most mycobacterial species. For example, the conventional disk diffusion method is not suitable for testing slowly growing mycobacteria because the drug diffuses throughout the medium before growth of the mycobacteria is significantly affected. The methods generally accepted for determining the antimicrobial susceptibility of mycobacteria are based on the growth of the microorganisms on solid or in liquid medium containing a specified concentration of a single drug.”
“Based on the current NCCLS guidelines, a rapid susceptibility testing method should be used in conjunction with rapid methods of primary culture and identification to allow the earliest possible detection of resistance.”
Sorry for the ancient reference but it should suffice because organism growth rates still determine the testing method. Generally, all susceptibility methods are used based on CLSI (formerly NCCLS) guidelines to which the public and IHTSDO do not have access. They are a purchased set of guidelines. The Mayo reference below is the best I can find as it actually references the CLSI guidelines.

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3197070/ Mtb testing, 2011 reference
There are rapid methods for susceptibility testing on Mtbc (a slow-growing organism) now also based on other reading so if we ever get AFB drugs for mapping, it behooves us to ask the method of testing.

Hi Craig,
We use Annotation Comment 48767-8 for such a comment. The definition reads “This is an observation code indicating that a particular observation represents a free text annotation comment that can be appended to some other observation such as a lab result.”
We like this better than the Service Comment series, because they can be used for a different intent in the receiving system than in your sending system, and the note could get misinterpreted. Both sides using 48767-8 would understand that this is additional information.
Hope this helps,

Hello Chuck,
“Normal” lab ranges are affected by age, sex, race and ethnicity. As such, there isn’t one normal range for the entire population on earth for most analytes.
I believe the [12.0,16.0] range you see in RELMA on 718-7 would be a recording of the reference range used by the submitter for that term. We are required to provide example reports with submissions, which would lend that information.
LOINC is intended to accompany the locally generated lab values, units of measure, and reference range. It is not intended to dictate the units of measure nor the reference range.
Hope this helps,

Hello! You are correct, both the SI derived unit of measure for pressure, the Pascal unit and the routinely used (but not SI based) millimeter of mercury (mmHg) measure a gas from a pressure stand point.
The property attribute you would be seeking for each gaseous analyte is PPRES
Thank you for asking,
Pam Banning
3M Health Information would also be interested in this information. I’ll forward to Dan Vreeman and John Hook through regular email. Hope we hear soon!

A term as you suggest would dilute out the value of Meaningful Use; the code itself could not isolate a particular assay for data mining. It also misrepresents the granularity that is within the database. The X Local codes alluded to above could be created locally; although a submission to Regenstrief is optimal suggestion. Please email or call for a quicker conversation to explain further and get you started in either direction.

Hello!
It is necessary to make submissions for codes that aren’t represented currently in the database. Check out the Users’ Manual Copyright Notice and License Item 6 for the mention of interim X codes as a placeholder. Use the RELMA tool to make necessary submissions.
Out of curiosity, is your laboratory of a specialty nature? Are you using the LOINC codes provided by your referral laboratories? The nature of mapping only the in house codes, and basic chemistries, serologies, hematologies, etc. at the result level do not usually encounter the issue being described. Our experiences at 3M have found a higher level of completion at the result code level than the order code level. The recent guidelines created by the Standards & Interoperability Work Group aLOINC Order Code have helped, and communications with Regenstrief continues.
Have a great week, Pam Banning pdbanning@mmm.com
Hello,
will the automated method of counting platelets not apply for the circumstance? I haven’t witnessed a divergence of hematology elements to be by a flow cytometry method. The hematology domain is basically methodless, manual and automated.
Best regards, Pam
Hello,
Please assure your HL7 message has an organism genus/species name as the answer, and search RELMA for MALDI TOF to see 4 possible options.
Please reply if you have further questions,
Have a great day, Pam
Hi Barry,
Please examine the HL7 messages of the outbound results, and determine how many OBX’s are generated and example answers are available. Also have at hand the package insert of the assays. Are you asking about result level or order level LOINC or both?
Looking forward to the discussion, Pam
