The phrase "assay level" is correct and usable in written English.
It can be used in contexts related to scientific testing, particularly in fields like chemistry or biology, where it refers to the concentration or amount of a substance being tested.
Example: "The assay level of the compound was found to be significantly higher than expected, indicating a potential error in the initial measurements."
Alternatives: "testing concentration" or "analysis level".
