    55134-1  Influenza virus A neuraminidase RNA [Identifier] in Isolate by Probe and target amplification method

    Is flagged as “Discouraged”.  And I find no comparable code for the Hemagglutinin RNA.

    A use-case I see coming is for H/N subtyping.  We currently have labs report each H and N tested for as a distinct Ct value and POS/NEG interpretation.  While this is the most complete way of reporting, it varies from what is normally reported out.  “H5N2” etc.  A single Identity code wouldn’t work because of mixed infections.  “H5N2 and N3”.  But a repeating sequence of codes similar to 55134-1 would convey what was found.  (It would leave it to the lab to look for the right Hs and Ns.)
