thanks for the information! I didn't realize it's gonna be a standardized process... Is there a way to avoid a systematic checkup and still get the certification? or any place to make it possible?

I have searched the whole forum before I asked, but couldn't find relevant info.
actually it's just hard for me to understand why I need to show such certificate in order to work in another EU 17 country, after living and working in CH for a long time... scientifically speaking

,my cells (or molecules) are all Swiss made already...
