Not really. Sure, statistics on whole populations favor whites and asians when it comes to test scores. But any doctor you may come in contact with has passed many tests of knowledge and ability at all levels of their education and career. They have seen many patients, have not had their medical license revoked, can still receive medical insurance, so on and so forth. Such a selection of individuals will not follow the distribution of intelligence one sees in the general population. At this point you are just as likely to have a crackpot white doctor as a crackpot black doctor.
