calcuLabIndicatorFn(value, lowerValue, upperValue)

Calculates the indicator (high, low, or normal) for a lab test result.

value — string, required: test result value (supports comparison operators)

lowerValue — string, optional: lower limit value (supports comparison operators)

upperValue — string, optional: upper limit value (supports comparison operators)

string/null:

calcuLabIndicatorFn2

calcuLabIndicatorFn2(value, lowerValue, upperValue, referValue, config)

Calculates the indicator for a lab test result (enhanced version, supports ratio and multiple evaluation strategies).

value — string, required: test result value

lowerValue — string, optional: absolute lower limit value

upperValue — string, optional: absolute upper limit value

referValue — string, conditional: reference value (required for Ratio mode)

config — string/object, required: configuration (JSON or object) with:
