We are discussing possible LOINC codes for a test described here: https://intermountainhealthcare.org/services/genomics/providers/rxmatch/
We think LOINC code 78046-0 might be appropriate for the order and 51969-4 might be appropriate for the result. But those both use system of Bld/Tiss. The test uses a buccal swab. Would system Bld/Tiss be appropriate or should a code with a more specific system buccal be requested. (As seen on 55198-6.)
We appreciate any input.
