# Function: computeFlag()

> **computeFlag**(`input`): `"unknown"` | `"in"` | `"low"` | `"high"`

Defined in: [packages/core/src/domain/lab/lab-flag.ts:33](https://github.com/pablo-albaladejo/kaiord/blob/3eacbe62ef72342d970523967cc5155b5935bb85/packages/core/src/domain/lab/lab-flag.ts#L33)

Classify a canonical value against the effective reference range.
Priority: report canonical bounds > report `refText` > catalog fallback
(sex-aware when `refBySex` and `sex` are present) > `"unknown"`. A `refText`
that does not parse to numeric bounds yields `"unknown"` (not highlighted).

## Parameters

### input

[`ComputeFlagInput`](../type-aliases/ComputeFlagInput.md)

## Returns

`"unknown"` | `"in"` | `"low"` | `"high"`
