Dear Shuja
In some cases Ohlbe's suggestion to perform the incurred sample reanalyis from replicate samples could be right. I made the bad experience that the incurred sample reanalyis from the same samples failed but the incurred sample reanalyis from replicate samples passed. It was impossible to find out the reason for this observation but the difference was significant. We suspected additional metabolizing steps due to freeze and thaw. This was not observed during method validation.
Kind regards
Dan
