    Great question, we have been challenged in the past to sort through this. This is the way we would look at it:

    When mapping, we would not consider a result on a urine sediment as something that might be ‘orderable’ either by the lab or by the physician, the only reason it gets reported is because it was identified in the urine microscopic during reporting process. The bacteria in synovial fluid, on the other hand, might be something that is specifically requested, so would be able to be ordered and reported (the order might be WBC’s and Bacteria for example).

    Hope that helps,

    Interesting comments. In Canada we use the 24 hour clock as our standard for these tests and it does eliminate any confusion. For the tests listed we provide:

    58645-3 Cortisol 1200h
    58643-8 Cortisol 2400h

    I agree that incorporating the 24 hour clock into the Long Common Name makes sense, so revised names would appear as:

    58645-3 Cortisol [Moles/volume] in Saliva (oral fluid) –1200h specimen
    58643-8 Cortisol [Moles/volume] in Saliva (oral fluid) –2400h specimen

    I wonder if it would be appropriate to correct the specimen type for LOINC 32133-1 to Plasma (from venus plasma). As there is no LOINC code for Lactate on Plasma, it seems redundant to specify venus plasma in this case. This would align with other LOINC codes that specify specific specimen types (BldA) when the generic type (Bld) is not sufficient. In this case there would be a code for Plasma and a code for arterial plasma. If LOINC code 32133-1 should not change, then perhaps a new code request for Lactate on Plasma based on the product Insert Karen references would be more appropriate.

    Appreciate any comments from other submitters or the folks at Regenstrief!

    Hi,

    The website that was provided at the meeting was:
    http://ivdconnectivity.org/

    I am not sure if that will contain all of the information you are looking for, but it does list the vendors that are participating.

    Hi Dan,

    Just wondering what the cost is for the training (if any?) and if I can post this information on our Canadian forum for labs? Is there a restriction in who can attend?

    Hi,

    In Canada we use LOINC to ask the question, so would map our Urine Culture to 630-4 as you have identified. For the result value of e coli, we would map to SNOMED CT and would put the concept ID from SNOMED CT in the Organism dictionary if possible.

    LOINC coding is for the purpose of the lab question and is not used for the lab answer or result value.

    If the dictionary won’t accept SNOMED CT codes, then at best you could create an internal coding system by identifying each possible result value with a code identifier of your own, and set that up in your table. I am not sure if that would make resulting any easier?
