Point of care testing (POCT)


My insitutions offer some POC tests like blood gas, gluscose, electrolytes, Hgb ad PT. We have received some requests asking if it is possible to differentiate the tests done from the lab and bedside in a data level.

As I know, the LOINC manual (section 1.2) states that the place of testing is explicitly excluded from the fully specified name.

My suggestion is, can we treat POCT is a kind of method for those blood tests?

It seems to me that POCT is kind of method of mesaurement worthwhile mentioning.

Any comment or idea?


One possible way is to identify that type of testing as a clinic. That is, give each it’s own name and location.

Perhaps your clinic name is now 892SST. Many facilities have multiple locations, such as 892 South Street and 992 South Street. The lab identifies these as ordering locations. You can request that the lab add 892POCT as an ordering location. You would use that on your lab requisitions and they would send results to the ordering provider from that clinic, as usual. All results could possibly be viewed for 892POCT, depending on your interface.

Another option: does the specimen type segregate them? Capillary or whole blood specimens vs serum/plasma? This would work for chemistries, but not hematologies.

what if only test name is given with result for example only glucose-positive is given. so how we map these test without any system,scale,unit etc

Hello Pavan,

It’s imperative to begin mapping with an extract that contains specific data requirement. See RELMA User’s Guide for requirements in creating your local file (LMOF). Mapping from only a display name won’t help you make progress. Ask the end user what is being reported? Does it chart to the clinician? It may be their positive glucose control, for example. If you have access to example reports to clinicians, more information can be gleaned.

All the best,

Glucose-124 how we code this ??

is there any default code in loinc and how should it given and when

Hello Pavan,

Have you watched the videos at https://loinc.org/learn/ ? There is a learning curve for the mapper, in addition to assuring you’ve got the best possible extract for your local terms to work from.

For the question on how to map Glucose-124, you need to have the information of specimen type (serum, urine, csf, etc) along with the units of measure. I also like to see the orderable test information, to assure we’re not dealing with a challenge test.

For the question of a default LOINC term, having a “one size fits all” term defeats the purpose of creating a computer-understood label or tag to accompany local terms in electronic data exchange. There are instances where a specialist review is used across multiple assays; there are role specific terms such as clinical biochemist review, coagulation specialist review, etc. You can find them by entering ’ review imp xxx ’ in RELMA

Would you like to share a portion of your mapping extract for adequacy review? You can email me at pdbanning@mmm.com.

Hope some of this helps you,


can you give an example of default loinc code ??

As mentioned yesterday, having default LOINC terms defeat the purpose of interoperability. The use case of identifying laboratory assays would not be met if all assays are tagged with the same term.

I would like to help you make traction in your project, even if it is only in initial stages. Please email me at pdbanning@mmm.com

when we import lab data in relma and then we process terms in Lab Auto Mapper after complete this we go to map to result in that we start maping. the relma show the accurate loinc code.

For example : In Local lab data there is lab test Leukocytes bld x 1000/ul . we import this in relma and then we open Lab Auto Mapper in that we process terms after this we go to map to result in that relma suggest loinc code 26464-8 Leukocytes [#/​volume] in Blood which is exact code.


so my question is that how relma software show such accurate result or suggestion to us. what is approach or logic behind this? how the relma software is able to give such a accurate out come. if there is any information regards this please give and any paper or websites about this software please give in attachment.


Hi Pavan,

RELMA is using your test name, specimen, and units of measure to find the correct code. You can find more information about how it works in the RELMA manual (https://loinc.org/download/relma-manual/).

The reason there is an appropriate LOINC match for “Leukocytes bld x 1000/ul” and not for “Glucose -124” is because the first one includes information about the specimen and units, as well as the analyte, while the second only includes the analyte.

CBC WO diff Bld panel there is 10 test so if CBC WO diff Bld panel was performed so we code CBC WO diff Bld panel or code 10 test separately And what if only 7 test was performed in CBC WO diff Bld panel so how we code this.

Hello Pavan,

Our team has found success in mapping all results of all panels/tests first. All orderables that are single result fields get the same LOINC for the order side. Returning to the panels/groups will allow you to choose the best LOINC term with the Required, Optional, Conditional, Reflex w/alternative of that panel. You’ll notice some panels only have suggested components, but none required. With none required, be sure the display and intent of the local panel fits the display and intent of the LOINC term.

The one strict rule we adhere to are the required fields of a panel. If there is not a good fit amongst the LOINC panels, you are encouraged to provide feedback to Regenstrief under the Content / Request New / Request Edit to Existing section.

Have a great week,


Sodium 136, potassium 4.6, how we code this lab data??

what is different between SI units and traditional units in lab ??

ABG pO2 was performed 2 time on one day then we give two code of ABG pO2 or one code ??
