Dear all,

the draft guideline states in Section 4.1.5 Accuracy, lines 196-198:

To enable evaluation of any trends over time within one run, it is recommended to demonstrate accuracy of QC samples over at least one of the runs with a size equivalent to a prospective analytical run.

According to the EUFEPS/EBF-workshop last April I would expect that this statement will 'make it' to the final version.

We have one validated method (GC/MS stable isotope IS) which is in routine use for numerous years. Until now we have analyzed ~8300 samples and had not a single batch rejected (86 batches, size 72-108 study samples/batch, average 96 samples without calibrators/QCs). What do you think? Will regulators insist in performing a new validation run in ~110 samples or would it be sufficient to refer to historical data?
