I asked my dentist about doing a bio-compadability test and he told me that he would do one for me , but all the test he had done on his past patients ,most if not all result came back as the same as every other pateint , so in my opinion what he just told me is he dosen't have to much faith in bio-compadability testing I am glad he is being honest with me , I trust him alot and take him at his word.
