At this point in time in the world of biocompatibility, there still are slight differences between what is expected depending on where you plan on marketing your medical device. So please select from below what best describes where you intend to market. If you plan to market in a country that isn't a choice, you can choose European Notified Body which will give you straight up ISO 10993-1 recommendations. Or, choose US FDA which tends to be the most comprehensive panel of testing as noted in their "Use of ISO 10993-1...". As time moves forward, more and more countries fall into just flat out acceptance of ISO 10993 test methods and methodologies. Japan may require different test methods and the USFDA may require additional tests or evaluations to be conducted.
