With chemical characterization of medical devices being first and foremost in medical device safety evaluations, it's more important than ever to make sure you're using the right lab. Lab capabilities range from the basic to the very full resource and we want to know what you look for in a lab when making the very important selection. We will publish the results about a week or two after posting to make sure everyone gets the chance to contribute. We aim to be a free and open medical device biocompatibility resource and give you the most honest and real content you can get anywhere! Thank you for completing this short survey, your contributions WILL help other biocompatibility professionals and may help shape future regulations and guidance documents.
