I am going to submit for a LOINC for a new panel for the above. It will include LOINC 22312-3 and 22315-6 as well as a new LOINC being requested as an interp for the previous LOINCs. This is a test message, but still true.
Your test message came through; all is well At first glance, there is one panel established, 53775-3, with three required elements (53776-1 is an interpretation element of IgM and total). Might it be suitable for your use?
