Clarification: LOINC for Sample Identifier

Hi,
Clarification - if states are already receiving the PLT in lineage reports that contains the specimen ID, Quest would like to not have to change that. We had to have that change for our state, but Wendy tells me they would to leave states as is due to resource limitations on the Quest side. Thanks!

Hello,
Quest let us know they are expanding their sending of variant results in HL7, and were including a PLT code in an OBX|2| to record the original specimen ID/accession number. Coding to add a PLT is possible but labor intensive for us. Riki found from Regenstrief that this LOINC could be used
LOINC 89873-4 — Unique identifier [Identifier] of Initial sample

We have asked Quest to start using this LOINC in those variant messages for the reporting of the original specimen ID to CT. So it would be available for others as well.
Thanks!

LOINC !!! BUT, at least in PA, we would have to then map this LOINC to "COVID-19" condition or it will fail to process and end up in our Error Queue. This presents an issue if the LOINC is ever used for anything but COVID, without a significant amount of side coding to make it 'smart'. Not a fan.

Can I assume - we should ask Quest - that like everything else for Covid, states may need to have a choice? It worked better for us, but not for others. So Quest could accommodate in their set ups for each agency?

Maybe a broader question to consider is which piece of information should be sent as the specimen ID versus in an additional OBX. In FL, Quest is the only CDC-contracted lab in production ELR that uses the lab-assigned sequence ID as the specimen ID, which means the additional OBX provides the original specimen ID/accession number (PLT221 or LOINC 89873-4). If Quest were to use the original specimen ID/accession number as the specimen ID, the additional OBX would instead reflect the lab-assigned sequence ID/sequencing study identifier (PLT2397 or LOINC 98062-3). While both options still require the use of an additional OBX to provide both pieces of information, I think the latter option provides additional benefits to jurisdictions (e.g., greater standardization in reporting structure, supports surveillance systems’ ability to group related lab results based on the specimen ID/accession number without additional coding).

This might be an agenda item for our upcoming conversations regarding sequencing reporting standards, but I figured it was worth a mention here 😊

NY does not have any issues with this as we can map the LOINC to an "Additional piece of information" for any disease.



Thanks.
