Where does “immunoassay” come from?
I appreciate the detailed instructions, but I need to flag an issue: the etymology chain provided traces "assay" backwards, but the headword is "immunoassay," which is a compound word formed from "immuno-" (from immunity/immune) + "assay."
The chain you've given doesn't account for the "immuno-" component. To write an accurate one-sentence origin summary for "immunoassay," I would need:
1. The etymology chain for the "immuno-" prefix, OR
2. Confirmation that I should treat this as "assay" only and note that immunoassay is a modern compound
Could you clarify which approach you'd like, or provide the complete chain for immunoassay?
