The phrase "a final assay" is correct and usable in written English.
It can be used in contexts related to testing, analysis, or evaluation, particularly in scientific or technical fields.
Example: "Before we proceed with the project, we need to conduct a final assay to ensure all components meet the required standards."
Alternatives: "a final analysis" or "a conclusive test".
