Estou com algumas dificuldades em organizar esta parte da frase:

**not as the concentration quantified, if it exceeds the range of fortified matrix calibration curves used for validation.


The lab reported non-compliant results of e.g. clenbuterol, **not as the concentration quantified, if it exceeds the range of fortified matrix calibration curves used for validation. Instead, the result is reported as higher than the concentration of the last point of the calibration curve (e.g. for clenbuterol detected > 0.6 μg/kg).

Obrigada!
