Hi Ohlbe,
Really? Let’s assume that the subject with concentrations >ULOQ is observed in the last batch and we are already close to the validated long-term stability. Even if we revalidate with a higher dilution, we may exhaust the storage interval – resulting in unacceptable results as well. In such a case we have to exclude the subject.
❝ You can't exclude subjects or data points because they are ULOQ: the ULOQ result would be the Cmax for that subject. If you exclude the data, you will bias the outcome of the study.
