Dear Members,

We determine the medium QC in our method validations by using the geometric mean of LLOQ and ULOQ to be in the range of concentration levels in study samples.

But in EMEA bioanalytical method validation guideline, medium QC is described to be around 50% of the calibration curve range.

Does using the geometric mean instead of the 50% of calibration curve range for calculating medium QC pose a problem during an EMEA audit?

Regards,

Haydonat
