Hi Ohlbe,

❝ 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.

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.
