Dear Ohlbe,

❝ The guideline does not ask for any statistical outlier test to be performed. If you have a subject with very low concentrations, calculate the geometric mean of the AUC of the reference without that subject. If the AUC of the subject for the reference product is lower than 5 % of that mean you have a possibility to exclude him. That's all.

It is stated that we have to remove outlier subjects for reference auc before making th geometric mean calculation. So I think that we have to include all the subjects inckuding the one we want to check and check for the outlier first and in case there is no outlier we then calculate the geometric mean and check for 5 %.
