Calculation method
Calculation method
Known status coverage (%)
Count declared present, absent and unknown cells in a rectangular supplied allergen matrix; unknown is never treated as absent.
Unknown cells (count)
Count declared present, absent and unknown cells in a rectangular supplied allergen matrix; unknown is never treated as absent.
Present counts by allergen column (JSON)
Count declared present, absent and unknown cells in a rectangular supplied allergen matrix; unknown is never treated as absent.

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- Record coverage only; does not establish allergen absence, cross-contact controls or legal label compliance. Supported limits: Finite numeric values bounded to 1e9 magnitude; lists and tables contain 1–100 records unless a stricter bound is stated. Inputs use the units shown. Lists explicitly paired by a method must have matching lengths; independent polynomial coefficient vectors may differ. Respect stated physical, interpolation, policy and computational domain limits.
