1278309610 96 My father in law is legally blind how can he obtain a glucose testing machine that will talk to him? his wife has alzheimers and can not really help him with his testing. they are on a very very tight fixed income. is there a machine that talks the results so he can hear the test number. would the blind association be able to help him get a machine at no cost.
